== DESCRIPTION:
"It's amazing how hard it is to find problems when caused by developers 
incorrectly modifying framework-generated files."

"i've always wanted to write a rake task to diff framework-generated files 
against their generated default for that very reason"

"I would install that gem/plugin if you released it."

Here you go, Chad!


== FEATURES/PROBLEMS:
See @DESCRIPTION for details on the problem.

The solution is simple, although not very elegant.  The _rails projectname_ command
builds the shell of a rails project with the intended directory structure and assorted files.
Here, we're simply using a diff tool against each of the framework generated files and displaying
the output.  Surely some of the differences that are detected are intentional and correct.  This
tool makes it easy to see what changed, and makes no judgement on the correctness of those changes.


== REQUIREMENTS:
* RubyGems
* diff available in your path
* A rails app you'd like to diff against the framework generated defaults

== INSTALL:

* sudo gem install rails_framework_diff


== ISSUES:
Some framework generated files include some erb syntax which is parsed during generation.  This tool
does not currently deal with that case, so those lines will appear as different.  Examples include
the rails config :session_key, etc.


== USAGE:
To use, make sure that the bin files of installed gems (this one, especially) are accessible via your $PATH
> rails_framework_diff project_name [rails version]
  project_name:  a relative path to the rails project to diff
  rails version: define only to diff against a different version of rails than is specified by the project
