+# A Multi-Framework [Composer](http://getcomposer.org) Library Installer
+
+[![Build Status](http://img.shields.io/travis/composer/installers.svg)](http://travis-ci.org/composer/installers)
+
+This is for PHP package authors to require in their `composer.json`. It will
+install their package to the correct location based on the specified package
+type.
+
+The goal of `installers` is to be a simple package type to install path map.
+Users can also customize the install path per package and package authors can
+modify the package name upon installing.
+
+`installers` isn't intended on replacing all custom installers. If your
+package requires special installation handling then by all means, create a
+custom installer to handle it.
+
+**Natively Supported Frameworks**:
+
+The following frameworks natively work with Composer and will be
+installed to the default `vendor` directory. `composer/installers`
+is not needed to install packages with these frameworks:
+
+* Aura
+* Symfony2
+* Yii
+* Yii2
+
+**Current Supported Package Types**:
+
+> Stable types are marked as **bold**, this means that installation paths
+> for those type will not be changed. Any adjustment for those types would
+> require creation of brand new type that will cover required changes.

+## Example `composer.json` File
+
+This is an example for a CakePHP plugin. The only important parts to set in your
+composer.json file are `"type": "cakephp-plugin"` which describes what your
+package is and `"require": { "composer/installers": "~1.0" }` which tells composer
+to load the custom installers.
+
+```json
+{
+    "name": "you/ftp",
+    "type": "cakephp-plugin",
+    "require": {
+        "composer/installers": "~1.0"
+    }
+}
+```
+
+This would install your package to the `Plugin/Ftp/` folder of a CakePHP app
+when a user runs `php composer.phar install`.
+
+So submit your packages to [packagist.org](http://packagist.org)!
+
+## Custom Install Paths
+
+If you are consuming a package that uses the `composer/installers` you can
+override the install path with the following extra in your `composer.json`:
+
+```json
+{
+    "extra": {
+        "installer-paths": {
+            "your/custom/path/{$name}/": ["shama/ftp", "vendor/package"]
+        }
+    }
+}
+```
+
+A package type can have a custom installation path with a `type:` prefix.
+
+``` json
+{
+    "extra": {
+        "installer-paths": {
+            "your/custom/path/{$name}/": ["type:wordpress-plugin"]
+        }
+    }
+}
+```
+
+This would use your custom path for each of the listed packages. The available
+variables to use in your paths are: `{$name}`, `{$vendor}`, `{$type}`.
+
+## Custom Install Names
+
+If you're a package author and need your package to be named differently when
+installed consider using the `installer-name` extra.
+
+For example you have a package named `shama/cakephp-ftp` with the type
+`cakephp-plugin`. Installing with `composer/installers` would install to the
+path `Plugin/CakephpFtp`. Due to the strict naming conventions, you as a
+package author actually need the package to be named and installed to
+`Plugin/Ftp`. Using the following config within your **package** `composer.json`
+will allow this:
+
+```json
+{
+    "name": "shama/cakephp-ftp",
+    "type": "cakephp-plugin",
+    "extra": {
+        "installer-name": "Ftp"
+    }
+}
+```
+
+Please note the name entered into `installer-name` will be the final and will
+not be inflected.
+
+## Contribute!
+
+* [Fork and clone](https://help.github.com/articles/fork-a-repo).
+* Run the command `php composer.phar install --dev` to install the dev
+  dependencies. See [Composer](https://github.com/composer/composer#installation--usage).
+* Use the command `phpunit` to run the tests. See [PHPUnit](http://phpunit.de).
+* Create a branch, commit, push and send us a
+  [pull request](https://help.github.com/articles/using-pull-requests).
+
+To ensure a consistent code base, you should make sure the code follows the
+[Coding Standards](http://symfony.com/doc/2.0/contributing/code/standards.html)
+which we borrowed from Symfony.
+
+If you would like to help, please take a look at the list of
+[issues](https://github.com/composer/installers/issues).
+
+### Should we allow dynamic package types or paths? No.
+What are they? The ability for a package author to determine where a package
+will be installed either through setting the path directly in their
+`composer.json` or through a dynamic package type: `"type":
+"framework-install-here"`.
+
+It has been proposed many times. Even implemented once early on and then
+removed. `installers` won't do this because it would allow a single package
+author to wipe out entire folders without the user's consent. That user would
+then come here to yell at us.

+PHP_Depend 0.11.0
+-----------------
+
+This release closes a critical bug that let PHP_Depend die with a E_FATAL when
+the used PHP version was 5.4 or greater.
+
+- Fixed #18976391: PHP_Depend's file cache implementation does not work with
+  PHP 5.4. Fixed with commit #06ce51a.
+
+PHP_Depend 0.10.6
+-----------------
+
+This release closes a critical bug in PHP_Depend's parser that produced
+false positiv error messages for classes named like 'True', 'False' or 
+'Null'
+
+- Fixed #5ac3e55: Unexpected token: True, line: 348, col: 49, file:...
+
+PHP_Depend 0.10.5
+-----------------
+
+This release closes two minor bugs in PHP_Depend. One incompatibility
+with PHP 5.2.x versions and one bug related to PHP_Depend's log
+behavior when PHP_Depend analyzes unstructured source code. This release
+was published on May the 20th 2011.
+
+- Fixed #13255437: PHP 5.2 Compatibility Issues. Fixed with commit
+  #8d4a095.
+- Fixed #13405179: PHP Depend report is not generated if all files do
+  not contain a class nor a function. Fixed with commit #554ade1.
+
+PHP_Depend 0.10.4
+-----------------
+
+This release contains an improvement in PHP_Depend's memory consumption.
+We have optimized the internal data structures in such a way that the
+memory footprint was reduced by ~30%. These values were measured for
+currently popular frameworks with a medium to large sized code base. The
+tests were run under ubuntu with PHP 5.2.17 and PHP 5.3.6.
+
+PHP_Depend 0.10.3
+-----------------
+
+This release closes a critial bug in PHP_Depend's analyzer locator code
+that prevents PHP_Depend from running on windows. This release was
+published on March the 02th 2011.
+
+- Fixed #10659085: Analyzer locator code does not work on windows. Fixed
+  with commit #0101798.
+
+PHP_Depend 0.10.2
+-----------------
+
+This release of PHP_Depend closes two bugs. One related to the start and
+end line properties of object property nodes in the syntax tree. The
+second fix closes a bug in PHP_Depend's implementation of the WMCi metric.
+Beside these two fixes this release implements three minor features, one
+design issue in the syntax tree api and the other two other features are
+related to the new metrics CE, CA, CBO and NPM.
+
+Additionally we have restructured PHP_Depend's directory structure from a
+custom, freestyle format to a directory layout that is similar to maven's
+convention. With this change we have fixed several issues and workarounds
+in PHP_Depend's build process.
+
+- Fixed #9936901: WMCi calculation is incorrect for overwritten methods.
+  Fixed with commit #69d079a.
+- Fixed #8927377: Invalid Start/End Line/Column for object property access.
+  Fixed with commit #fc57264.
+- Implemented #9069393: Replace optional NULL argument of setPackage()
+  with separate method. Implemented with commit #1282cdb.
+- Implemented #9069871: Implement efferent- and afferent-coupling for
+  classes. Implemented with commit #07537c2.
+- Implemented #9997915: Implement Number of Public Methods metric.
+  Implemented with commit #2dd3ebf.
+
+PHP_Depend 0.10.1
+-----------------
+
+- Fixed #9634613: Notice: Undefined property $___temp___. Fixed with
+  commit #5fb6900.
+
+PHP_Depend 0.10.0
+-----------------
+
+- Fixed #113: PHP fatal error when an unserialized object graph
+  none NodeI instances. Fixed with commit #c0f4384.
+- Implemented #130: Simplify PHP_Depend's ASTCompoundVariable and skip
+  nested ASTCompoundExpression node instance. Implemented in svn revision
+  number #1344.
+- Implemented #131: Add new method isThis() to PHP_Depend's ASTVariable
+  class. Implemented in svn revision #1291.
+- Implemented #132: Housekeeping: Cleanup the PHP_Depend_Input package test
+  code. Done in svn revision #1366.
+- Implemented #139: Implement Post-/Pre- Increment/Decrement. Implemented
+  in svn revision #1317.
+- Implemented #143: Support PHP's alternative control structure syntax.
+  Done in svn revision #1375.
+- Implemented #146: Implement PHP's declare-statement. Done in subversion

+/**
+ * The php source parser.
+ *
+ * With the default settings the parser includes annotations, better known as
+ * doc comment tags, in the generated result. This means it extracts the type
+ * information of @var tags for properties, and types in @return + @throws tags
+ * of functions and methods. The current implementation tries to ignore all
+ * scalar types from <b>boolean</b> to <b>void</b>. You should disable this
+ * feature for project that have more or less invalid doc comments, because it
+ * could produce invalid results.
+ *
+ * <code>
+ *   $parser->setIgnoreAnnotations();
+ * </code>
+ *
+ * <b>Note</b>: Due to the fact that it is possible to use the same name for
+ * multiple classes and interfaces, and there is no way to determine to which
+ * package it belongs, while the parser handles class, interface or method
+ * signatures, the parser could/will create a code tree that doesn't reflect the
+ * real source structure.

+
+You can pass a file name or a directory name containing PHP source
+code to PHPMD.
+
+The PHPMD Phar distribution includes the rule set files inside
+its archive, even if the "rulesets/codesize.xml" parameter above looks 
+like a filesystem reference.
+
+Command line options
+====================
+
+- Notice that the default output is in XML, so you can redirect it to
+  a file and XSLT it or whatever
+
+- You can also use shortened names to refer to the built-in rule sets,
+  like this: ::
+
+    phpmd PHP/Depend/DbusUI/ xml codesize
+
+- The command line interface also accepts the following optional arguments:
+
+  - ``--minimumpriority`` - The rule priority threshold; rules with lower
+    priority than they will not be used.
+
+  - ``--reportfile`` - Sends the report output to the specified file, 
+    instead of the default output target ``STDOUT``.
+
+  - ``--suffixes`` - Comma-separated string of valid source code filename 
+    extensions.
+
+  - ``--exclude`` - Comma-separated string of patterns that are used to ignore 
+    directories.
+
+  - ``--strict`` - Also report those nodes with a @SuppressWarnings annotation. 
+
+  An example command line: ::
+
+    phpmd PHP/Depend/DbusUI xml codesize --reportfile phpmd.xml --suffixes .php
+
+Using multiple rule sets
+````````````````````````
+
+PHPMD uses so called rule sets that configure/define a set of rules which will 
+be applied against the source under test. The default distribution of PHPMD is
+already shipped with a few default sets, that can be used out-of-box. You can
+call PHPMD's cli tool with a set's name to apply this configuration: ::
+
+  ~ $ phpmd /path/to/source text codesize
+
+But what if you would like to apply more than one rule set against your source?
+You can also pass a list of rule set names, separated by comma to PHPMD's cli
+tool: ::
+
+  ~ $ phpmd /path/to/source text codesize,unusedcode,naming
+
+You can also mix custom `rule set files`__ with build-in rule sets: ::
+
+  ~ $ phpmd /path/to/source text codesize,/my/rules.xml
+
+__ /documentation/creating-a-ruleset.html
+
+That's it. With this behavior you can specify you own combination of rule sets
+that will check the source code.
+
+Using multiple source files and folders
+```````````````````````````````````````
+
+PHPMD also allowes you to specify multiple source directories in case you want
+to create one output for certain parts of your code ::
+
+ ~ $ phpmd /path/to/code,index.php,/another/place/with/code text codesize
+
+
+Exit codes
+==========
+
+PHPMD's command line tool currently defines three different exit codes.
+
+- *0*, This exit code indicates that everything worked as expected. This means
+  there was no error/exception and PHPMD hasn't detected any rule violation
+  in the code under test.
+- *1*, This exit code indicates that an error/exception occured which has
+  interrupted PHPMD during execution.
+- *2*, This exit code means that PHPMD has processed the code under test
+  without the occurence of an error/exception, but it has detected rule
+  violations in the analyzed source code.
+
+Renderers
+=========
+
+At the moment PHPMD comes with the following three renderers:
+
+- *xml*, which formats the report as XML.
+- *text*, simple textual format.
+- *html*, single HTML file with possible problems.

+                              two new rules. The first one utilizes the Coupling
+                              Between Objects (CBO) metric to detect strongly

+=========================
+PHPMD - PHP Mess Detector
+=========================
+
+This is the project site of *PHPMD*. It is a spin-off project of
+`PHP Depend`__ and aims to be a PHP equivalent of the well known
+Java tool `PMD`__. PHPMD can be seen as an user friendly and easy
+to configure frontend for the raw metrics measured by PHP Depend.
+
+__ http://pdepend.org
+__ http://pmd.sourceforge.net
+
+What PHPMD does is: It takes a given PHP source code base and look 
+for several potential problems within that source. These problems
+can be things like:
+
+- Possible bugs
+- Suboptimal code
+- Overcomplicated expressions
+- Unused parameters, methods, properties
+
+PHPMD is a young project and so it only provides a limited set of
+pre defined rules, compared with it's brother PMD, that detect code
+smells and possible errors within the analyzed source code. Checkout
+the `rules section`__ to learn more about all implemented rules.

+====================
+PHPMD ant task usage
+====================
+
+To ease the usage of PHPMD in your build process we provide an `ant task`__
+that integrates PHPMD into the `ant`__ build tool. The ant task jar file can
+be found in the `download`__ section of the PHPMD homepage.
+
+__ http://ant.apache.org/manual/targets.html
+__ http://ant.apache.org/
+__ /download/extensions#ant-task
+
+To make the task available in your ant build file you have two options.
+The first option is to copy or link the ``*.jar`` file into the ``lib``
+directory of your ant installation. ::
+
+  mapi@arwen ~ $ wget \
+       http://phpmd.org/download/extensions/ant-phpmd-0.1.0.jar
+  ...
+  mapi@arwen ~ $ ln -s ~/ant-phpmd-0.1.0.jar /opt/ant/lib/ant-phpmd.jar
+
+The second option is to call ant with the command line switch ``-lib`` ::
+
+  mapi@arwen ~ $ ant -lib ant-phpmd-0.1.0.jar
+
+
+Now we can start using PHPMD in our ant ``build.xml`` file by adding
+a task definition that informs ant about the new task and registers
+it with a custom identifier. ::
+
+  <?xml version="1.0" encoding="UTF-8" ?>
+  <project name="phpmd.example" default="example" basedir=".">
+
+      <taskdef name="phpmd" classname="org.phpmd.ant.PHPMDTask"/>
+
+  </project>
+
+Now the PHPMD task can be called through an xml element named ``<phpmd />``
+in this build: ::
+
+  <?xml version="1.0" encoding="UTF-8"?>
+  <project name="phpmd.example" default="example" basedir=".">
+
+      <taskdef name="phpmd" classname="org.phpmd.ant.PHPMDTask"/>
+
+      <target name="example">
+          <phpmd rulesetfiles="unusedcode" failonerror="off">
+              <formatter type="xml" toFile="${basedir}/pmd.xml" />
+              <fileset dir="${basedir}/PHPMD">
+                  <include name="*.php" />
+              </fileset>
+          </phpmd>
+      </target>
+
+  </project>
+
+Parameters
+==========
+
+The following attributes can be defined on the PHPMD task xml-element.
+
+===================== ========================================================================================================================= ================================================
+ Attribute             Description                                                                                                               Required
+===================== ========================================================================================================================= ================================================
+ rulesetfiles          A comma delimited list of ruleset files ('rulesets/basic.xml,rulesets/design.xml') or identifiers of build-in rulesets.   Yes, unless the ruleset nested element is used
+ failonerror           Whether or not to fail the build if any errors occur while processing the files                                           No
+ failOnRuleViolation   Whether or not to fail the build if PHPMD finds any problems                                                              No
+ minimumPriority       The rule priority threshold; rules with lower priority than they will not be used                                         No
+===================== ========================================================================================================================= ================================================
+
+Nested xml elements
+===================
+
+The ``<formatter />`` specifies the format of and the output file to
+which the report is written.
+
+**Parameters**
+
+=========== =================================================================== ==========
+ Attribute   Description                                                         Required
+=========== =================================================================== ==========
+ format      The report output format. Supported formats are xml,html and text.  Yes
+ toFile      A filename into which the report is written                         Yes
+=========== =================================================================== ==========
+
+The ``<ruleset />`` xml element is another way to specify rulesets. Here
+is a modified version of the previous example: ::
+
+  <target name="example">
+      <phpmd failonerror="off">
+          <formatter type="text" toFile="${basedir}/pmd.xml" />
+          <ruleset>unusedcode</ruleset>
+          <ruleset>codesize</ruleset
+          <fileset dir="${basedir}/PHPMD">
+              <include name="*.php" />
+          </fileset>
+      </phpmd>
+  </target>
+
+Postprocessing the report file with XSLT
+========================================
+
+There are several XSLT scripts which can be used to transform the XML
+report into some nice html pages. To do this, make sure you use the
+XML formatter in the PHPMD task invocation, i.e.: ::
+
+  <formatter type="xml" toFile="${builddir}/~report.xml"/>
+
+Then, after the end of the PHPMD task, do this: ::
+
+  <xslt in="${builddir}/~report.xml"
+        style="${basedir}/report.xslt"
+        out="${reportdir}/report.html" />
+

+==============================
+Howto create a custom rule set
+==============================
+
+If you would like to only pick some of the rules that come with PHPMD and
+you want to customize some of the pre defined thresholds, you can do this
+by creating your own rule set file that references a custom collection of
+rules with an individual configuration.
+
+Starting with an empty ruleset.xml file
+=======================================
+
+The simpliest way to start with a new rule set is to copy one of the 
+existing files and remove all the rule-tags from the document body. 
+Otherwise you can use the following example as a template for your own 
+rule set file. You should change the content of the ``@name`` attribute 
+and ``<description />`` element to something that describes the purpose
+of this set. ::
+
+  <?xml version="1.0"?>
+  <ruleset name="My first PHPMD rule set"
+           xmlns="http://pmd.sf.net/ruleset/1.0.0"
+           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+           xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 
+                       http://pmd.sf.net/ruleset_xml_schema.xsd"
+           xsi:noNamespaceSchemaLocation="
+                       http://pmd.sf.net/ruleset_xml_schema.xsd">
+      <description>
+          My custom rule set that checks my code...
+      </description>
+  </ruleset>
+
+Adding rule references to the new ruleset.xml file
+==================================================
+
+The first thing we would like to do is to add all `unused code`__ rules
+to the new rule set file. This can simply be done with a ``<rule />`` 
+element that references the entire `unused code`__ rule set that comes 
+with PHPMD.
+
+__ /rules/unusedcode.html
+__ /rules/unusedcode.html
+
+::
+
+  <?xml version="1.0"?>
+  <ruleset name="My first PHPMD rule set"
+           xmlns="http://pmd.sf.net/ruleset/1.0.0"
+           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+           xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 
+                       http://pmd.sf.net/ruleset_xml_schema.xsd"
+           xsi:noNamespaceSchemaLocation="
+                       http://pmd.sf.net/ruleset_xml_schema.xsd">
+      <description>
+          My custom rule set that checks my code...
+      </description>
+
+      <!-- Import the entire unused code rule set -->
+      <rule ref="rulesets/unusedcode.xml" />
+  </ruleset>
+
+That's it. Now the custom rule set applies all `unused code`__ rules
+against the analyzed source code.
+
+__ /rules/unusedcode.html
+
+We would also like to use the `cyclomatic complexity`__ rule from the
+existing `codesize`__ set in our custom rule set. To achieve this we can
+reuse the same syntax with a ``<rule />`` element and a ``@ref`` attribute.
+
+__ /rules/codesize.html#cyclomaticcomplexity
+__ /rules/codesize.html
+
+::
+
+  <?xml version="1.0"?>
+  <ruleset name="My first PHPMD rule set"
+           xmlns="http://pmd.sf.net/ruleset/1.0.0"
+           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+           xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 
+                       http://pmd.sf.net/ruleset_xml_schema.xsd"
+           xsi:noNamespaceSchemaLocation="
+                       http://pmd.sf.net/ruleset_xml_schema.xsd">
+      <description>
+          My custom rule set that checks my code...
+      </description>
+
+      <!-- Import the entire unused code rule set -->
+      <rule ref="rulesets/unusedcode.xml" />
+
+      <!-- Import the entire cyclomatic complexity rule -->
+      <rule ref="rulesets/codesize.xml/CyclomaticComplexity" />
+  </ruleset>
+
+Now that the new rule set uses the `cyclomatic complexity`__ rule we would 
+also like to customize some of the rule's properties. First we will 
+increase the rule's priority to the highest possible priority value ``1`` 
+and we also decrease the threshold when the rule reports a violation. This 
+customization can be done with same xml elements that are used to configure
+the original rule, so that you can take a look at one of the original rule 
+set file. 
+
+__ /rules/codesize.html#cyclomaticcomplexity
+
+::
+
+  <?xml version="1.0"?>
+  <ruleset name="My first PHPMD rule set"
+           xmlns="http://pmd.sf.net/ruleset/1.0.0"
+           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+           xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 
+                       http://pmd.sf.net/ruleset_xml_schema.xsd"
+           xsi:noNamespaceSchemaLocation="
+                       http://pmd.sf.net/ruleset_xml_schema.xsd">
+      <description>
+          My custom rule set that checks my code...
+      </description>
+
+      <!-- Import the entire unused code rule set -->
+      <rule ref="rulesets/unusedcode.xml" />
+
+      <!-- 
+          Import the entire cyclomatic complexity rule and 
+          customize the rule configuration.
+      -->
+      <rule ref="rulesets/codesize.xml/CyclomaticComplexity">
+          <priority>1</priority>
+          <properties>
+              <property name="reportLevel" value="5" />
+          </properties>
+      </rule>
+  </ruleset>
+
+You should know that PHPMD handles all custom settings additive. This 
+means that PHPMD keeps the original configuration for every setting that
+isn't customized in a rule reference.
+
+Excluding rules from a rule set
+===============================
+
+Finally we would like to reuse the `naming`__ rule set of PHPMD. But we 
+don't like the two variable naming rules, so that we must exclude them
+from out rule set file. This exclusion can be achieved by declaring an
+``<exclude />`` element within the rule reference. This element has an
+attribute ``@name`` which specifies the name of the excluded rule.
+
+__ /rules/naming.html
+
+
+::
+
+  <?xml version="1.0"?>
+  <ruleset name="My first PHPMD rule set"

+Conclusion
+==========
+
+With PHPMD's rule set syntax it is possible to customize all aspects of 
+rules for your own needs and you can reuse every existing rule set xml file
+in your own set. You should take a look at PHPMD's rule `documentation`__ 
+if it happens that you don't know what rules exist or you don't know 
+exactly, which settings are available for one rule, while you create your 
+own set of rules. Another good source of information are the rule set
+`files`__ that are shipped with PHPMD.

+Command line usage
+==================
+
+Type phpmd [filename|directory] [report format] [ruleset file], i.e: ::
+
+  mapi@arwen ~ $ phpmd PHP/Depend/DbusUI/ xml rulesets/codesize.xml
+  <?xml version="1.0" encoding="UTF-8" ?>

+      </violation>
+    </file>
+  </pmd>
+
+You can pass a file name or a directory name containing PHP source
+code to PHPMD.
+
+The PHPMD Phar distribution includes the rule set files inside
+its archive, even if the "rulesets/codesize.xml" parameter above looks 
+like a filesystem reference.
+
+Command line options
+====================
+
+- Notice that the default output is in XML, so you can redirect it to
+  a file and XSLT it or whatever
+
+- You can also use shortened names to refer to the built-in rule sets,
+  like this: ::
+
+    phpmd PHP/Depend/DbusUI/ xml codesize
+
+- The command line interface also accepts the following optional arguments:
+
+  - ``--minimumpriority`` - The rule priority threshold; rules with lower
+    priority than they will not be used.
+
+  - ``--reportfile`` - Sends the report output to the specified file, 
+    instead of the default output target ``STDOUT``.
+
+  - ``--suffixes`` - Comma-separated string of valid source code filename 
+    extensions.
+
+  - ``--exclude`` - Comma-separated string of patterns that are used to ignore 
+    directories.
+
+  - ``--strict`` - Also report those nodes with a @SuppressWarnings annotation. 
+
+  An example command line: ::
+
+    phpmd PHP/Depend/DbusUI xml codesize --reportfile phpmd.xml --suffixes .php
+
+
+Using multiple rule sets
+````````````````````````
+
+PHPMD uses so called rule sets that configure/define a set of rules which will 
+be applied against the source under test. The default distribution of PHPMD is
+already shipped with a few default sets, that can be used out-of-box. You can
+call PHPMD's cli tool with a set's name to apply this configuration: ::
+
+  ~ $ phpmd /path/to/source text codesize
+
+But what if you would like to apply more than one rule set against your source?
+You can also pass a list of rule set names, separated by comma to PHPMD's cli
+tool: ::
+
+  ~ $ phpmd /path/to/source text codesize,unusedcode,naming
+
+You can also mix custom `rule set files`__ with build-in rule sets: ::
+
+  ~ $ phpmd /path/to/source text codesize,/my/rules.xml
+
+__ /documentation/creating-a-ruleset.html
+
+That's it. With this behavior you can specify you own combination of rule sets
+that will check the source code.
+
+Exit codes
+==========
+
+PHPMD's command line tool currently defines three different exit codes.
+
+- *0*, This exit code indicates that everything worked as expected. This means
+  there was no error/exception and PHPMD hasn't detected any rule violation
+  in the code under test.
+- *1*, This exit code indicates that an error/exception occured which has
+  interrupted PHPMD during execution.
+- *2*, This exit code means that PHPMD has processed the code under test
+  without the occurence of an error/exception, but it has detected rule
+  violations in the analyzed source code.
+
+Renderers
+=========
+
+At the moment PHPMD comes with the following three renderers:
+
+- *xml*, which formats the report as XML.
+- *text*, simple textual format.
+- *html*, single HTML file with possible problems.

+PHPMD Suppressing Warnings
+==========================
+
+You can use doc comment annotations to exclude methods or classes 
+from PHPMD or to suppress special rules for some software artifacts. ::
+
+  /**
+   * This will suppress all the PMD warnings in
+   * this class.
+   *
+   * @SuppressWarnings(PHPMD)
+   */
+  class Bar {
+      function  foo() {
+          $baz = 23;
+      }
+  }
+
+Or you can suppress one rule with an annotation like this: ::
+
+  /**
+   *
+   */
+  class Bar {
+      /**
+       * This will suppress UnusedLocalVariable
+       * warnings in this method

+       * @SuppressWarnings(PHPMD.UnusedLocalVariable)
+       */
+      public function foo() {
+          $baz = 42;
+      }
+  }
+
+The ``@SuppressWarnings`` annotation of PHPMD also supports some
+wildcard exclusion, so that you can suppress several warnings with
+a single annotation. ::
+
+  /**
+   * Suppress all rules containing "unused" in this
+   * class
+   *
+   * @SuppressWarnings("unused")
+   */
+  class Bar {
+      private $unusedPrivateField = 42;
+      public function foo($unusedFormalParameter = 23)
+      {
+          $unusedLocalVariable = 17;
+      }
+      private function unusedPrivateMethod() {
+      }
+  }
+
+A doc comment can contain multiple ``@SuppressWarnings`` annotations,
+so that you can exclude multiple rules by name. ::
+
+  /**
+   * Suppress all warnings from these two rules.
+   *
+   * @SuppressWarnings(PHPMD.LongVariable)
+   * @SuppressWarnings(PHPMD.UnusedLocalVariable)

+Howto write a Rule for PHPMD
+============================
+
+:Author:       Manuel Pichler
+:Copyright:    All rights reserved
+:Description:  This article describes the how to develop custom rule classes
+               for PHPMD (PHP Mess Detector). You will learn how to develop
+               different rule types and how to configure them in a custom rule
+               set file, so that PHPMD can use those rules for its analysis
+               runs. Additionally you will learn several other aspects about
+               PHPMD, like the violation message template engine and how to
+               write customizable rule classes.
+:Keywords:     NPM, Number of Public Methods, Software Metrics, PHPMD, PMD, rule set, rule, xml, violation, AST, Abstract Syntax Tree
+
+This article describes how you can extend PHPMD with custom rule classes that
+can be used to detect design issues or errors in the analyzed source code.
+
+Let us start with some architecture basics behind PHPMD. All rules in PHPMD
+must at least implement the `PHPMD\Rule`__ interface. You can also extend
+the abstract rule base class `\PHPMD\AbstractRule`__ which already provides
+an implementation of all required infrastructure methods and application logic,
+so that the only task which is left to you is the implementation of the
+concrete validation code of your rule. To implement this validation-code the
+PHPMD rule interface declares the ``apply()`` method which will be invoked by
+the application during the source analysis phase. ::
+
+  require_once 'PHPMD/AbstractRule.php';
+
+  class Com_Example_Rule_NoFunctions extends \PHPMD\AbstractRule
+  {
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          // Check constraints against the given node instance
+      }
+  }
+
+The ``apply()`` method gets an instance of `\PHPMD\AbstractNode`__ as
+argument. This node instance represents the different high level code artifacts
+found in the analyzed source code. In this context high level artifact means
+*interfaces*, *classes*, *methods* and *functions*. But how do we tell PHPMD
+which of these artifacts are interesting for our rule, because we do not want
+duplicate implementations of the descision code in every rule? To solve this
+problem PHPMD uses so-called marker interfaces. The only purpose of these
+interfaces is to label a rule class, which says: Hey I'm interessted in nodes
+of type class and interface, or I am interessted in function artifacts. The
+following list shows the available marker interfaces:
+
+- `\PHPMD\Rule\ClassAware`__
+- `\PHPMD\Rule\FunctionAware`__
+- `\PHPMD\Rule\InterfaceAware`__
+- `\PHPMD\Rule\MethodAware`__
+
+With this marker interfaces we can now extend the previous example, so that
+the rule will be called for functions found in the analyzed source code. ::
+
+  class Com_Example_Rule_NoFunctions
+         extends \PHPMD\AbstractRule
+      implements \PHPMD\Rule\FunctionAware
+  {
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          // Check constraints against the given node instance
+      }
+  }
+
+And because our coding guideline forbids functions every call to the ``apply()``
+method will result in a rule violation. Such a violation can be reported to
+PHPMD through the ``addViolation()`` method. The rule inherits this helper
+method from it's parent class `\PHPMD\AbstractRule`__. ::
+
+  class Com_Example_Rule_NoFunctions // ...
+  {
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          $this->addViolation($node);
+      }
+  }
+
+That's it. The only thing left to do is adding a configuration entry for this
+rule to a rule set file. This ruleset file is an XML document where all settings
+of one or more rules can be configured, so that everyone can customize an
+existing rule without any changes the rule's source. The syntax of the rule set
+file is completly adapted from PHPMD's inspiring example `PMD`__. To get
+started with a custom rule set you should take a look at one of the existing
+`XML files`__ and then adapt one of the rule configurations for a newly created
+rule. The most important elements of a rule configuration are:
+
+- *@name*: Human readable name for the rule.
+- *@message*: The error/violation message that will shown in the report.
+- *@class*: The full qualified class name of the rule.
+- *priority*: The priority for the rule. This can be a value in the range 1-5,
+  where 1 is the highest priority and 5 the lowest priority.
+
+::
+
+  <ruleset name="example.com rules"
+         xmlns="http://pmd.sf.net/ruleset/1.0.0"
+         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
+         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
+
+      <rule name="FunctionRule"
+            message = "Please do not use functions."
+            class="Com_Example_Rule_NoFunctions"
+            externalInfoUrl="http://example.com/phpmd/rules.html#functionrule">
+
+          <priority>1</priority>
+      </rule>
+  </ruleset>
+
+The previous listing shows a basic rule set file that configures all required
+settings for the created example rule. For more details on PHPMD's rule set
+file format you should take a look a the `Create a custom rule set`__ tutorial.
+
+Finally the real world test. Let's assume we have saved the rule class in a
+file ``Com/Example/Rule/NoFunction.php`` that is somewhere in the PHP
+``include_path`` and we have saved the rule set in a file named
+``example-rule.xml``. No we can test the rule from the command line with the
+following command: ::
+
+  ~ $ phpmd /my/source/example.com text /my/rules/example-rule.xml
+
+  /my/source/example.com/functions.php:2    Please do not use functions.
+
+That's it. Now we have a first custom rule class that can be used with PHPMD.
+
+Writing a rule based on an existing Software Metric
+===================================================
+
+Since the root goal for the development of PHPMD was the implementation of a
+simple and user friendly interface for PHP_Depend, we will show you in this
+section how to develop a rule class, that uses a software metric measured by
+`PHP_Depend`__ as input data.
+
+In this section you will learn how to access software metrics for a given
+`\PHPMD\AbstractNode`__ instance. And you will learn how to use PHPMD's
+configuration backend in such a way, that thresholds and other settings can
+be customized without changing any PHP code. Additionally you will see how
+the information content of an error message can be improved.
+
+The first thing we need now is a software metric that we want to use as basis
+for the new rule. A complete and up2date list of available software metrics
+can be found PHP_Depend's `metric catalog`__. For this article we choose the
+`Number of Public Methods (npm)`__ metric and we define an upper and a lower
+threshold for our rule. The upper threshold is ``10``, because we think a class
+with more public methods exposes to much of its privates and should be
+refactored into two or more classes. For the lower threshold we choose ``1``,
+because a class without any public method does not expose any service to
+surrounding application.
+
+The following code listing shows the entire rule class skeleton. As you can
+see, this class implements the `\PHPMD\Rule\ClassAware`__ interface, so that
+PHPMD knows that this rule will only be called for classes. ::
+
+  class Com_Example_Rule_NumberOfPublicMethods
+         extends \PHPMD\AbstractRule
+      implements \PHPMD\Rule\ClassAware
+  {
+      const MINIMUM = 1,
+            MAXIMUM = 10;
+
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          // Check constraints against the given node instance
+      }
+  }
+
+Now that we have the rule skeleton we must access the ``npm`` metric which
+is associated with the given node instance. All software metrics calculated for
+a node object can directly be accessed through the ``getMetric()`` method of the
+node instance. This method takes a single parameter, the abbreviation/acronym
+of the metric as documented in PHP_Depends `metric catalog`__. ::
+
+  class Com_Example_Rule_NumberOfPublicMethods
+         extends \PHPMD\AbstractRule
+      implements \PHPMD\Rule\ClassAware
+  {
+      const MINIMUM = 1,
+            MAXIMUM = 10;
+
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          $npm = $node->getMetric('npm');
+          if ($npm < self::MINIMUM || $npm > self::MAXIMUM) {
+              $this->addViolation($node);
+          }
+      }
+  }
+
+That's the coding part for the metric based rule. Now we must add this class
+to a rule set file.
+
+::
+
+  <ruleset name="example.com rules"
+         xmlns="http://pmd.sf.net/ruleset/1.0.0"
+         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
+         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
+
+      <!-- ... -->
+
+      <rule name="NumberOfPublics"
+            message = "The context class violates the NPM metric."
+            class="Com_Example_Rule_NumberOfPublicMethods"
+            externalInfoUrl="http://example.com/phpmd/rules.html#numberofpublics">
+
+          <priority>3</priority>
+      </rule>
+  </ruleset>
+
+Now we can run PHPMD with this rule set file and it will report us all classes
+that do not fulfill our requirement for the NPM metric. But as promised, we
+will make this rule more customizable, so that it can be adjusted for different
+project requirements. Therefore we will replace the two constants ``MINIMUM``
+and ``MAXIMUM`` with properties that can be configured in the rule set file.
+So let us start with the modified rule set file. ::
+
+  <ruleset name="example.com rules"
+         xmlns="http://pmd.sf.net/ruleset/1.0.0"
+         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
+         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
+
+      <!-- ... -->
+
+      <rule name="NumberOfPublics"
+            message = "The context class violates the NPM metric."
+            class="Com_Example_Rule_NumberOfPublicMethods"
+            externalInfoUrl="http://example.com/phpmd/rules.html#numberofpublics">
+
+          <priority>3</priority>
+          <properties>
+              <property name="minimum"
+                        value="1"
+                        description="Minimum number of public methods." />
+              <property name="maximum"
+                        value="10"
+                        description="Maximum number of public methods." />
+          </properties>
+      </rule>
+  </ruleset>
+
+In PMD rule set files you can define as many properties for a rule as you like.
+All of them will be injected into a rule instance by PHPMD's runtime
+environment and then can be accessed through the ``get<type>Property()``
+methods. Currently PHPMD supports the following getter methods.
+
+- ``getBooleanProperty()``
+- ``getIntProperty()``
+
+So now let's modify the rule class and replace the hard coded constants with
+the configurable properties. ::
+
+  class Com_Example_Rule_NumberOfPublicMethods
+         extends \PHPMD\AbstractRule
+      implements \PHPMD\Rule\ClassAware
+  {
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          $npm = $node->getMetric('npm');
+          if ($npm < $this->getIntProperty('minimum') ||
+              $npm > $this->getIntProperty('maximum')
+          ) {
+              $this->addViolation($node);
+          }
+      }
+  }
+
+Now we are nearly done, but one issue is still left out. When we execute this
+rule, the user will get the message *"The context class violates the NPM
+metric."* which isn't really informative, because he must manually check if the
+upper or lower threshold was exceeded and what the actual thresholds are. To
+provide more information about a rule violation you can use PHPMD's minimalistic
+template/placeholder engine for violation messages. With this engine you can
+define violation messages with placeholders, that will be replaced with actual
+values. The format for such placeholders is ``'{' + \d+ '}'``. ::
+
+  <ruleset name="example.com rules"
+         xmlns="http://pmd.sf.net/ruleset/1.0.0"
+         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0 http://pmd.sf.net/ruleset_xml_schema.xsd"
+         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">
+
+      <!-- ... -->
+
+      <rule name="NumberOfPublics"
+            message = "The class {0} has {1} public method, the threshold is {2}."
+            class="Com_Example_Rule_NumberOfPublicMethods"
+            externalInfoUrl="http://example.com/phpmd/rules.html#numberofpublics">
+
+          <priority>3</priority>
+          <properties>
+              <property name="minimum"
+                        value="1"
+                        description="Minimum number of public methods." />
+              <property name="maximum"
+                        value="10"
+                        description="Maximum number of public methods." />
+          </properties>
+      </rule>
+  </ruleset>
+
+Now we can adjust the rule class in such a manner, that it will set the correct
+values for the placeholders ``{0}``, ``{1}`` and ``{2}`` ::
+
+  class Com_Example_Rule_NumberOfPublicMethods
+         extends \PHPMD\AbstractRule
+      implements \PHPMD\Rule\ClassAware
+  {
+      public function apply(\PHPMD\AbstractNode $node)
+      {
+          $min = $this->getIntProperty('minimum');
+          $max = $this->getIntProperty('maximum');
+          $npm = $node->getMetric('npm');
+
+          if ($npm < $min) {
+              $this->addViolation($node, array(get_class($node), $npm, $min));
+          } else if ($npm > $max) {
+              $this->addViolation($node, array(get_class($node), $npm, $max));
+          }
+      }
+  }
+
+If we run this version of the rule we will get an error message like the one
+shown in the following figure. ::
+
+  The class FooBar has 42 public method, the threshold is 10.
+
+Writing a rule based on the Abstract Syntax Tree
+================================================
+
+Now we will learn how to develop a PHPMD rule that utilizes PHP_Depend's
+abstract syntax tree to detect violations or possible error in the analyzed
+source code. The ability to access PHP_Depend's abstract syntax tree gives you
+the most powerful way to write rules for PHPMD, because you can analyze nearly
+all apects of the software under test. The syntax tree can be accessed through
+the ``getFirstChildOfType()`` and ``findChildrenOfType()`` methods of the
+`\PHPMD\AbstractNode`__ class.
+
+In this example we will implement a rule that detects the usage of the new and
+controversial PHP feature ``goto``. Because we all know and agree that ``goto``
+was already bad in Basic, we would like to prevent our developers from using
+the bad feature. Therefore we implement a PHPMD rule, that searches through
+PHP_Depend's for the ``goto`` language construct.
+
+Because the ``goto`` statement cannot be found in classes and interfaces, but
+in methods and functions, the new rule class must implement the two marker
+interfaces `\PHPMD\Rule\FunctionAware`__ and `\PHPMD\Rule\MethodAware`__.
+
+::
+
+  namespace PHPMD\Rule\Design;
+
+  use PHPMD\AbstractNode;
+  use PHPMD\AbstractRule;
+  use PHPMD\Rule\MethodAware;
+  use PHPMD\Rule\FunctionAware;
+
+  class GotoStatement extends AbstractRule implements MethodAware, FunctionAware
+  {
+      public function apply(AbstractNode $node)
+      {
+          foreach ($node->findChildrenOfType('GotoStatement') as $goto) {
+              $this->addViolation($goto, array($node->getType(), $node->getName()));
+          }
+      }
+  }
+
+As you can see, we are searching for the string ``GotoStatement`` in the
+previous example. This is a shortcut notation used by PHPMD to address concrete
+PHP_Depend syntax tree nodes. All abstract syntax tree classes in PDepend
+have the following format: ::
+
+  \PDepend\Source\AST\ASTGotoStatement
+
+where ::
+
+  \PDepend\Source\AST\AST
+
+is fixed and everything else depends on the node type. And this fixed part of
+the class name can be ommitted in PHPMD when searching for an abstract syntax
+tree node. To implement additional rules you should take a look at PHP_Depend's
+`Code package`__ where you can find all currently supported code nodes.
+
+Conclusion
+==========
+
+In this article we have shown you several ways to implement custom rules for
+PHPMD. If you think one of your rules could be reusable for other projects and
+user, don't hesitate to propose your custom rules on the project's issue tracker
+at `GitHub`__ or open a pull request.

+:Copyright:    All rights reserved
+:Description:  This document describes the news features and bugfixes of the
+               next feature release 1.1.0 of PHPMD. This version provides two
+               new rules, one that utilizes the CBO metric to detect strong
+               coupled classes and a second on that detects the usage of PHP's
+               goto statement. Additionally this release closes a minor bug
+               in the LongVariable rule.
+:Keywords:     Release, Version, Features, Bugfixes, Coupling Between Objects, CBO, Goto Statement, PHPUnit
+
+Version 1.1.0 of PHPMD was released on March the 20th 2011. The key features
+for this release were two new rules. The first one utilizes the `Coupling
+Between Objects (CBO)`__ metric to detect strongly coupled classes. The second
+one detects the usage of PHP's questionable ``goto`` statement. Beside that
+we have closed a minor bug in the LongVariable rule, where also private
+properties with descriptive names were reported. And finally we have replaced
+deprecated PHPUnit features in the PHPMD's test suite, so that PHPMD's tests
+should now work with PHPUnit 3.4.x and 3.5.x without deprecated warnings.
+
+Features
+--------
+
+- Implemented `#10474873`__: Add rule for PHP's goto statement. Implemented
+  with commit `#2745a20`__.
+- Implemented `#10474987`__: Implement rule for CBO metric. Implemented with
+  commit `#14277b4`__.
+- Implemented `#11012465`__: Replace deprecated PHPUnit features in test suite.
+  Implemented with commit `#4adb88d`__.
+
+Bugfixes
+--------
+
+- Fixed `#10096717`__: LongVariable rule should not apply on private
+  properties. Fixed with commit `#f063bc9`__.

+================
+Clean Code Rules
+================
+
+The Clean Code ruleset contains a collection of rules that enforce
+software design principles such as the SOLID Principles and Object
+Callisthenics.
+
+They are very strict and cannot easily be followed without any violations.
+If you use this ruleset you should:
+
+1. Select important packages that should follow this ruleset and others that
+   don't
+2. Set a treshold for failures and not fail at the first occurance.
+
+ElseExpression
+==============
+
+Since: PHPMD 1.5
+
+An if expression with an else branch is never necessary. You can rewrite the
+conditions in a way that the else is not necessary and the code becomes simpler
+to read.  To achieve this use early return statements. To achieve this you may
+need to split the code it several smaller methods. For very simple assignments
+you could also use the ternary operations.
+
+Example: ::
+
+    class Foo
+    {
+        public function bar($flag)
+        {
+            if ($flag) {
+                // one branch
+            } else {
+                // another branch
+            }
+        }
+    }
+
+BooleanArgumentFlag
+===================
+
+A boolean flag argument is a reliable indicator for a violation of
+the Single Responsibility Principle (SRP). You can fix this problem
+by extracting the logic in the boolean flag into its own class
+or method.
+
+Example: ::
+
+    class Foo {
+        public function bar($flag = true) {
+        }
+    }
+
+StaticAccess
+============
+
+Static acccess causes inexchangable dependencies to other classes and leads to
+hard to test code. Avoid using static access at all costs and instead inject
+dependencies through the constructor. The only case when static access is
+acceptable is when used for factory methods.
+
+Example: ::
+
+    class Foo
+    {
+        public function bar()
+        {
+            Bar::baz();
+        }
+    }

+===============
+Code Size Rules
+===============
+
+The Code Size Ruleset contains a collection of rules that find code size related problems.
+
+CyclomaticComplexity
+====================
+
+Since: PHPMD 0.1
+
+Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.
+
+
+Example: ::
+
+  // Cyclomatic Complexity = 12
+  class Foo {
+  1   public function example()  {
+  2       if ($a == $b)  {
+  3           if ($a1 == $b1) {
+                  fiddle();
+  4           } else if ($a2 == $b2) {
+                  fiddle();
+              }  else {
+                  fiddle();
+              }
+  5       } else if ($c == $d) {
+  6           while ($c == $d) {
+                  fiddle();
+              }
+  7        } else if ($e == $f) {
+  8           for ($n = 0; $n < $h; $n++) {
+                  fiddle();
+              }
+          } else{
+              switch ($z) {
+  9               case 1:
+                      fiddle();
+                      break;
+  10              case 2:
+                      fiddle();
+                      break;
+  11              case 3:
+                      fiddle();
+                      break;
+  12              default:
+                      fiddle();
+                      break;
+              }
+          }
+      }
+  }
+
+This rule has the following properties:
+
+=================================== =============== ===================================================================
+ Name                                Default Value   Description                                                       
+=================================== =============== ===================================================================
+ reportLevel                         10              The Cyclomatic Complexity reporting threshold                     
+ showClassesComplexity               true            Indicate if class average violation should be added to the report 
+ showMethodsComplexity               true            Indicate if class average violation should be added to the report 
+=================================== =============== ===================================================================
+
+NPathComplexity
+===============
+
+Since: PHPMD 0.1
+
+The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity.
+
+
+Example: ::
+
+  class Foo {
+      function bar() {
+          // lots of complicated code
+      }
+  }
+
+This rule has the following properties:
+
+=================================== =============== ===============================
+ Name                                Default Value   Description                   
+=================================== =============== ===============================
+ minimum                             200             The npath reporting threshold 
+=================================== =============== ===============================
+
+ExcessiveMethodLength
+=====================
+
+Since: PHPMD 0.1
+
+Violations of this rule usually indicate that the method is doing too much. Try to reduce the method size by creating helper methods and removing any copy/pasted code.
+
+
+Example: ::
+
+  class Foo {
+      public function doSomething() {
+          print("Hello world!" . PHP_EOL);
+          print("Hello world!" . PHP_EOL);
+          // 98 copies omitted for brevity.
+      }
+  }
+
+This rule has the following properties:
+
+=================================== =============== =====================================
+ Name                                Default Value   Description                         
+=================================== =============== =====================================
+ minimum                             100             The method size reporting threshold 
+=================================== =============== =====================================
+
+ExcessiveClassLength
+====================
+
+Since: PHPMD 0.1
+
+Long Class files are indications that the class may be trying to do too much. Try to break it down, and reduce the size to something manageable.
+
+
+Example: ::
+
+  class Foo {
+    public function bar() {
+      // 1000 lines of code
+    }
+  }
+
+This rule has the following properties:
+
+=================================== =============== ====================================
+ Name                                Default Value   Description                        
+=================================== =============== ====================================
+ minimum                             1000            The class size reporting threshold 
+=================================== =============== ====================================
+
+ExcessiveParameterList
+======================
+
+Since: PHPMD 0.1
+
+Long parameter lists can indicate that a new object should be created to wrap the numerous parameters. Basically, try to group the parameters together.
+
+
+Example: ::
+
+  class Foo {
+      public function addData(
+          $p0, $p1, $p2, $p3, $p4, $p5,
+          $p5, $p6, $p7, $p8, $p9, $p10) {
+      }
+  }
+
+This rule has the following properties:
+
+=================================== =============== =========================================
+ Name                                Default Value   Description                             
+=================================== =============== =========================================
+ minimum                             10              The parameter count reporting threshold 
+=================================== =============== =========================================
+
+ExcessivePublicCount
+====================
+
+Since: PHPMD 0.1
+
+A large number of public methods and attributes declared in a class can indicate the class may need to be broken up as increased effort will be required to thoroughly test it.
+
+
+Example: ::
+
+  public class Foo {
+      public $value;
+      public $something;
+      public $var;
+      // [... more more public attributes ...]
+  
+      public function doWork() {}
+      public function doMoreWork() {}
+      public function doWorkAgain() {}
+      // [... more more public methods ...]
+  }
+
+This rule has the following properties:
+
+=================================== =============== =====================================
+ Name                                Default Value   Description                         
+=================================== =============== =====================================
+ minimum                             45              The public item reporting threshold 
+=================================== =============== =====================================
+
+TooManyFields
+=============
+
+Since: PHPMD 0.1
+
+Classes that have too many fields could be redesigned to have fewer fields, possibly through some nested object grouping of some of the information. For example, a class with city/state/zip fields could instead have one Address field.
+
+
+Example: ::
+
+  class Person {
+     protected $one;
+     private $two;
+     private $three;
+     [... many more fields ...]
+  }
+
+This rule has the following properties:
+
+=================================== =============== ======================================
+ Name                                Default Value   Description                          
+=================================== =============== ======================================
+ maxfields                           15              The field count reporting threshold  
+=================================== =============== ======================================
+
+TooManyMethods
+==============
+
+Since: PHPMD 0.1
+
+A class with too many methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects.
+
+This rule has the following properties:
+
+=================================== =============== =======================================
+ Name                                Default Value   Description                           
+=================================== =============== =======================================
+ maxmethods                          10              The method count reporting threshold  
+=================================== =============== =======================================
+
+ExcessiveClassComplexity
+========================
+
+Since: PHPMD 0.2.5
+
+The WMC of a class is a good indicator of how much time and effort is required to modify and maintain this class. A large number of methods also means that this class has a greater potential impact on derived classes.
+
+
+Example: ::
+
+  class Foo {
+      public function bar()  {
+          if ($a == $b)  {
+              if ($a1 == $b1) {
+                  fiddle();
+              } else if ($a2 == $b2) {
+                  fiddle();
+              }  else {
+              }
+          }
+      }
+      public function baz()  {
+          if ($a == $b)  {
+              if ($a1 == $b1) {
+                  fiddle();
+              } else if ($a2 == $b2) {
+                  fiddle();
+              }  else {
+              }
+          }
+      }
+      // Several other complex methods
+  }
+
+This rule has the following properties:
+
+=================================== =============== ========================================
+ Name                                Default Value   Description                            
+=================================== =============== ========================================
+ maximum                             50              The maximum WMC tolerable for a class.

+===================
+Controversial Rules
+===================
+
+This ruleset contains a collection of controversial rules.
+
+Superglobals
+============
+
+Since: PHPMD 0.2
+
+Accessing a super-global variable directly is considered a bad practice. These variables should be encapsulated in objects that are provided by a framework, for instance.
+
+
+Example: ::
+
+  class Foo {
+      public function bar() {
+          $name = $_POST['foo'];
+      }
+  }
+
+CamelCaseClassName
+==================
+
+Since: PHPMD 0.2
+
+It is considered best practice to use the CamelCase notation to name classes.
+
+
+Example: ::
+
+  class class_name {
+  }
+
+CamelCasePropertyName
+=====================
+
+Since: PHPMD 0.2
+
+It is considered best practice to use the camelCase notation to name attributes.
+
+
+Example: ::
+
+  class ClassName {
+      protected $property_name;
+  }
+
+CamelCaseMethodName
+===================
+
+Since: PHPMD 0.2
+
+It is considered best practice to use the CamelCase notation to name methods.
+
+
+Example: ::
+
+  class ClassName {
+      public function get_name() {
+      }
+  }
+
+CamelCaseParameterName
+======================
+
+Since: PHPMD 0.2
+
+It is considered best practice to use the camelCase notation to name parameters.
+
+
+Example: ::
+
+  class ClassName {
+      public function doSomething($user_name) {
+      }
+  }
+
+CamelCaseVariableName
+=====================
+
+Since: PHPMD 0.2
+
+It is considered best practice to use the camelCase notation to name variables.
+
+
+Example: ::
+
+  class ClassName {
+      public function doSomething() {
+          $data_module = new DataModule();
+      }
+  }

+Design Rules
+============
+
+The Design Ruleset contains a collection of rules that find software design related problems.
+
+ExitExpression
+==============
+
+Since: PHPMD 0.2
+
+An exit-expression within regular code is untestable and therefore it should be avoided. Consider to move the exit-expression into some kind of startup script where an error/exception code is returned to the calling environment.
+
+
+Example: ::
+
+  class Foo {
+      public function bar($param)  {
+          if ($param === 42) {
+              exit(23);
+          }
+      }
+  }
+
+EvalExpression
+==============
+
+Since: PHPMD 0.2
+
+An eval-expression is untestable, a security risk and bad practice. Therefore it should be avoided. Consider to replace the eval-expression with regular code.
+
+
+Example: ::
+
+  class Foo {
+      public function bar($param)  {
+          if ($param === 42) {
+              eval('$param = 23;');
+          }
+      }
+  }
+
+GotoStatement
+=============
+
+Since: PHPMD 1.1.0
+
+Goto makes code harder to read and it is nearly impossible to understand the control flow of an application that uses this language construct. Therefore it should be avoided. Consider to replace Goto with regular control structures and separate methods/function, which are easier to read.
+
+
+Example: ::
+
+  class Foo {
+      public function bar($param)  {
+          A:
+          if ($param === 42) {
+              goto X;
+          }
+          Y:
+          if (time() % 42 === 23) {
+              goto Z;
+          }
+          X:
+          if (time() % 23 === 42) {
+              goto Y;
+          }
+          Z:
+          return 42;                 
+      }
+  }
+
+NumberOfChildren
+================
+
+Since: PHPMD 0.2
+
+A class with an excessive number of children is an indicator for an unbalanced class hierarchy. You should consider to refactor this class hierarchy.
+
+
+
+This rule has the following properties:
+
+=================================== =============== =============================================
+ Name                                Default Value   Description                                 
+=================================== =============== =============================================
+ minimum                             15              Maximum number of acceptable child classes. 
+=================================== =============== =============================================
+
+DepthOfInheritance
+==================
+
+Since: PHPMD 0.2
+
+A class with many parents is an indicator for an unbalanced and wrong class hierarchy. You should consider to refactor this class hierarchy.
+
+
+
+This rule has the following properties:
+
+=================================== =============== ==============================================
+ Name                                Default Value   Description                                  
+=================================== =============== ==============================================
+ minimum                             6               Maximum number of acceptable parent classes. 
+=================================== =============== ==============================================
+
+CouplingBetweenObjects
+======================
+
+Since: PHPMD 1.1.0
+
+A class with too many dependencies has negative impacts on several quality aspects of a class. This includes quality criteria like stability, maintainability and understandability
+
+
+Example: ::
+
+  class Foo {
+      /**
+       * @var \foo\bar\X
+       */
+      private $x = null;
+  
+      /**
+       * @var \foo\bar\Y
+       */
+      private $y = null;
+  
+      /**
+       * @var \foo\bar\Z
+       */
+      private $z = null;
+  
+      public function setFoo(\Foo $foo) {}
+      public function setBar(\Bar $bar) {}
+      public function setBaz(\Baz $baz) {}
+  
+      /**
+       * @return \SplObjectStorage
+       * @throws \OutOfRangeException
+       * @throws \InvalidArgumentException
+       * @throws \ErrorException
+       */
+      public function process(\Iterator $it) {}
+  
+      // ...
+  }
+
+This rule has the following properties:
+
+=================================== =============== ============================================
+ Name                                Default Value   Description                                
+=================================== =============== ============================================
+ minimum                             13              Maximum number of acceptable dependencies.

+Current Rulesets
+================
+
+List of rulesets and rules contained in each ruleset.
+
+- `Code Size Rules`__: The Code Size Ruleset contains a collection of rules that find code size related problems.
+- `Controversial Rules`__: This ruleset contains a collection of controversial rules.
+- `Design Rules`__: The Code Size Ruleset contains a collection of rules that find software design related problems.
+- `Naming Rules`__: The Naming Ruleset contains a collection of rules about names - too long, too short, and so forth.
+- `Unused Code Rules`__: The Unused Code Ruleset contains a collection of rules that find unused code.

+
+Code Size Rules
+===============
+
+- `CyclomaticComplexity`__: Complexity is determined by the number of decision points in a method plus one for the method entry. The decision points are 'if', 'while', 'for', and 'case labels'. Generally, 1-4 is low complexity, 5-7 indicates moderate complexity, 8-10 is high complexity, and 11+ is very high complexity.
+- `NPathComplexity`__: The NPath complexity of a method is the number of acyclic execution paths through that method. A threshold of 200 is generally considered the point where measures should be taken to reduce complexity.
+- `ExcessiveMethodLength`__: Violations of this rule usually indicate that the method is doing too much. Try to reduce the method size by creating helper methods and removing any copy/pasted code.
+- `ExcessiveClassLength`__: Long Class files are indications that the class may be trying to do too much. Try to break it down, and reduce the size to something manageable.
+- `ExcessiveParameterList`__: Long parameter lists can indicate that a new object should be created to wrap the numerous parameters. Basically, try to group the parameters together.
+- `ExcessivePublicCount`__: A large number of public methods and attributes declared in a class can indicate the class may need to be broken up as increased effort will be required to thoroughly test it.
+- `TooManyFields`__: Classes that have too many fields could be redesigned to have fewer fields, possibly through some nested object grouping of some of the information. For example, a class with city/state/zip fields could instead have one Address field.
+- `TooManyMethods`__: A class with too many methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects.
+- `ExcessiveClassComplexity`__: The WMC of a class is a good indicator of how much time and effort is required to modify and maintain this class. A large number of methods also means that this class has a greater potential impact on derived classes.

+
+Controversial Rules
+===================
+
+- `Superglobals`__: Accessing a super-global variable directly is considered a bad practice. These variables should be encapsulated in objects that are provided by a framework, for instance.
+- `CamelCaseClassName`__: It is considered best practice to use the CamelCase notation to name classes.
+- `CamelCasePropertyName`__: It is considered best practice to use the camelCase notation to name attributes.
+- `CamelCaseMethodName`__: It is considered best practice to use the CamelCase notation to name methods.
+- `CamelCaseParameterName`__: It is considered best practice to use the camelCase notation to name parameters.
+- `CamelCaseVariableName`__: It is considered best practice to use the camelCase notation to name variables.

+
+Naming Rules
+============
+
+- `ShortVariable`__: Detects when a field, local, or parameter has a very short name.
+- `LongVariable`__: Detects when a field, formal or local variable is declared with a long name.
+- `ShortMethodName`__: Detects when very short method names are used.
+- `ConstructorWithNameAsEnclosingClass`__: A constructor method should not have the same name as the enclosing class, consider to use the PHP 5 __construct method.
+- `ConstantNamingConventions`__: Class/Interface constant nanmes should always be defined in uppercase.
+- `BooleanGetMethodName`__: Looks for methods named 'getX()' with 'boolean' as the return type. The convention is to name these methods 'isX()' or 'hasX()'.

+CHANGELOG
+=========
+
+2.2.0
+-----
+
+ * added ArrayNodeDefinition::canBeEnabled() and ArrayNodeDefinition::canBeDisabled()
+   to ease configuration when some sections are respectively disabled / enabled
+   by default.
+ * added a `normalizeKeys()` method for array nodes (to avoid key normalization)
+ * added numerical type handling for config definitions
+ * added convenience methods for optional configuration sections to ArrayNodeDefinition
+ * added a utils class for XML manipulations
+
+2.1.0
+-----
+
+ * added a way to add documentation on configuration
+ * implemented `Serializable` on resources
+ * LoaderResolverInterface is now used instead of LoaderResolver for type
+   hinting

+Config Component
+================
+
+Config provides the infrastructure for loading configurations from different
+data sources and optionally monitoring these data sources for changes. There
+are additional tools for validating, normalizing and handling of defaults that
+can optionally be used to convert from different formats to arrays.
+
+Resources
+---------
+
+You can run the unit tests with the following command:
+
+    $ cd path/to/Symfony/Component/Config/
+    $ composer.phar install
+    $ phpunit
+

+ * Container is a dependency injection container.
+ *
+ * It gives access to object instances (services).
+ *
+ * Services and parameters are simple key/pair stores.
+ *
+ * Parameter and service keys are case insensitive.
+ *
+ * A service id can contain lowercased letters, digits, underscores, and dots.
+ * Underscores are used to separate words, and dots to group services
+ * under namespaces:
+ *
+ * <ul>
+ *   <li>request</li>
+ *   <li>mysql_session_storage</li>
+ *   <li>symfony.mysql_session_storage</li>
+ * </ul>
+ *
+ * A service can also be defined by creating a method named
+ * getXXXService(), where XXX is the camelized version of the id:
+ *
+ * <ul>
+ *   <li>request -> getRequestService()</li>
+ *   <li>mysql_session_storage -> getMysqlSessionStorageService()</li>
+ *   <li>symfony.mysql_session_storage -> getSymfony_MysqlSessionStorageService()</li>
+ * </ul>
+ *
+ * The container can have three possible behaviors when a service does not exist:
+ *
+ *  * EXCEPTION_ON_INVALID_REFERENCE: Throws an exception (the default)
+ *  * NULL_ON_INVALID_REFERENCE:      Returns null
+ *  * IGNORE_ON_INVALID_REFERENCE:    Ignores the wrapping command asking for the reference
+ *                                    (for instance, ignore a setter if the service does not exist)

+DependencyInjection Component
+=============================
+
+DependencyInjection manages your services via a robust and flexible Dependency
+Injection Container.
+
+Here is a simple example that shows how to register services and parameters:
+
+```php
+use Symfony\Component\DependencyInjection\ContainerBuilder;
+use Symfony\Component\DependencyInjection\Reference;
+
+$sc = new ContainerBuilder();
+$sc
+    ->register('foo', '%foo.class%')
+    ->addArgument(new Reference('bar'))
+;
+$sc->setParameter('foo.class', 'Foo');
+
+$sc->get('foo');
+```
+
+Method Calls (Setter Injection):
+
+```php
+$sc = new ContainerBuilder();
+
+$sc
+    ->register('bar', '%bar.class%')
+    ->addMethodCall('setFoo', array(new Reference('foo')))
+;
+$sc->setParameter('bar.class', 'Bar');
+
+$sc->get('bar');
+```
+
+Factory Class:
+
+If your service is retrieved by calling a static method:
+
+```php
+$sc = new ContainerBuilder();
+
+$sc
+    ->register('bar', '%bar.class%')
+    ->setFactoryClass('%bar.class%')
+    ->setFactoryMethod('getInstance')
+    ->addArgument('Aarrg!!!')
+;
+$sc->setParameter('bar.class', 'Bar');
+
+$sc->get('bar');
+```
+
+File Include:
+
+For some services, especially those that are difficult or impossible to
+autoload, you may need the container to include a file before
+instantiating your class.
+
+```php
+$sc = new ContainerBuilder();
+
+$sc
+    ->register('bar', '%bar.class%')
+    ->setFile('/path/to/file')
+    ->addArgument('Aarrg!!!')
+;
+$sc->setParameter('bar.class', 'Bar');
+
+$sc->get('bar');
+```
