 <b>NOTE:</b> +java_compile+ is a hypothetical method that invokes the
 java compiler.
 
+== Importing Dependencies
+
+Any ruby file (including other rakefiles) can be included with a
+standard Ruby +require+ command.  The rules and declarations in the
+required file are just added to the definitions already accumulated.
+
+Because the files are loaded _before_ the rake targets are evaluated,
+the loaded files must be "ready to go" when the rake command is
+invoked.  This make generated dependency files difficult to use.  By
+the time rake gets around to updating the dependencies file, it is too
+late to load it.
+
+The +import+ command addresses this by specifying a file to be loaded
+_after_ the main rakefile is loaded, but _before_ any targets on the
+command line are specified.  In addition, if the file name matches an
+explicit task, that task is invoked before loading the file.  This
+allows dependency files to be generated and used in a single rake
+command invocation.
+
+=== Example:
+
+  require 'rake/loaders/makefile'
+
+  file ".depends.mf" => [SRC_LIST] do |t|
+    sh "makedepend -f- -- #{CFLAGS} -- #{t.prerequisites} > #{t.name}"
+  end
+
+  import ".depends.mf"
+
+If ".depends" does not exist, or is out of date w.r.t. the source
+files, a new ".depends" file is generated using +makedepend+ before
+loading.
+
 == Comments
 
 Standard Ruby comments (beginning with "#") can be used anywhere it is
 legal in Ruby source code, including comments for tasks and rules.
 However, if you wish a task to be described using the "-T" switch,
 then you need to use the +desc+ command to describe the task.
 
-Example:
+=== Example:
 
   desc "Create a distribution package"
   task :package => [ ... ] do ... end

+= Rake 0.5.0 Released
+
+Although it has only been two weeks since the last release, we have
+enough updates to the Rake program to make it time for another
+release.
+
+== Changes
+
+Here are the changes for version 0.5.3 ...
+
+* FileLists have been extensively changed so that they mimic the
+  behavior of real arrays even more closely.  In particular,
+  operations on FileLists that return a new collection (e.g. collect,
+  reject) will now return a FileList rather than an array.  In
+  addition, several places where FileLists were not properly expanded
+  before use have been fixed.
+
+* A method (+ext+) to simplify the handling of file extensions was
+  added to String and to Array.
+
+* The 'testrb' script in test/unit tends to silently swallow syntax
+  errors in test suites.  Because of that, the default test loader is
+  now a rake-provided script.  You can still use 'testrb' by setting
+  the loader flag in the test task to :testrb.  (See the API documents
+  for TestTask for all the loader flag values).
+
+* FileUtil methods (e.g. cp, mv, install) are now declared to be
+  private.  This will cut down on the interference with user defined
+  methods of the same name.
+
+* Fixed the verbose flag in the TestTask so that the test code is
+  controlled by the flag.  Also shortened up some failure messages.
+  (Thanks to Tobias Luetke for the suggestion).
+
+* Rules will now properly detect a task that can generate a source
+  file.  Previously rules would only consider source files that were
+  already present.
+
+* Added an +import+ command that allows Rake to dynamically import
+  dependendencies into a running Rake session.  The +import+ command
+  can run tasks to update the dependency file before loading them.
+  Dependency files can be in rake or make format, allowing rake to
+  work with tools designed to generate dependencies for make.
+
+== What is Rake
+
+Rake is a build tool similar to the make program in many ways.  But
+instead of cryptic make recipes, Rake uses standard Ruby code to
+declare tasks and dependencies.  You have the full power of a modern
+scripting language built right into your build tool.
+
+== Availability
+
+The easiest way to get and install rake is via RubyGems ...
+
+  gem install rake    (you may need root/admin privileges)
+
+Otherwise, you can get it from the more traditional places:
+
+Home Page:: http://rake.rubyforge.org/
+Download::  http://rubyforge.org/project/showfiles.php?group_id=50
+
+== Thanks
+
+As usual, it was input from users that drove a alot of these changes.
+Thanks to ...
+
+* Brian Gernhardt for the rules fix (especially for the patience to
+  explain the problem to me until I got what he was talking about).
+* Stefan Lang for pointing out problems in the dark corners of the
+  FileList implementation.
+* Alexey Verkhovsky pointing out the silently swallows syntax errors
+  in tests.
+* Tobias Luetke for beautifying the test task output.
+* Sam Roberts for some of the ideas behind dependency loading.
