+home :: https://github.com/seattlerb/ruby_parser
+bugs :: https://github.com/seattlerb/ruby_parser/issues
+rdoc :: http://docs.seattlerb.org/ruby_parser
+
+== DESCRIPTION:
+
+ruby_parser (RP) is a ruby parser written in pure ruby (utilizing
+racc--which does by default use a C extension). It outputs
+s-expressions which can be manipulated and converted back to ruby via
+the ruby2ruby gem.
+
+As an example:
+
+    def conditional1 arg1
+      return 1 if arg1 == 0
+      return 0
+    end
+
+becomes:
+
+    s(:defn, :conditional1, s(:args, :arg1),
+      s(:if,
+        s(:call, s(:lvar, :arg1), :==, s(:lit, 0)),
+        s(:return, s(:lit, 1)),
+        nil),
+      s(:return, s(:lit, 0)))
+
+Tested against 801,039 files from the latest of all rubygems (as of 2013-05):
+
+* 1.8 parser is at 99.9739% accuracy, 3.651 sigma
+* 1.9 parser is at 99.9940% accuracy, 4.013 sigma
+* 2.0 parser is at 99.9939% accuracy, 4.008 sigma
+* 2.6 parser is at 99.9972% accuracy, 4.191 sigma
+* 3.0 parser has a 100% parse rate.
+  * Tested against 2,672,412 unique ruby files across 167k gems.
+  * As do all the others now, basically.
+
+== FEATURES/PROBLEMS:
+
+* Pure ruby, no compiles.
+* Includes preceding comment data for defn/defs/class/module nodes!
+* Incredibly simple interface.
+* Output is 100% equivalent to ParseTree.
+  * Can utilize PT's SexpProcessor and UnifiedRuby for language processing.
+* Known Issue: Speed is now pretty good, but can always improve:
+  * RP parses a corpus of 3702 files in 125s (avg 108 Kb/s)
+  * MRI+PT parsed the same in 67.38s (avg 200.89 Kb/s)
+* Known Issue: Code is much better, but still has a long way to go.
+* Known Issue: Totally awesome.
+* Known Issue: line number values can be slightly off. Parsing LR sucks.
+
+== SYNOPSIS:
+
+  RubyParser.new.parse "1+1"
+  # => s(:call, s(:lit, 1), :+, s(:lit, 1))
+
+You can also use Ruby19Parser, Ruby18Parser, or RubyParser.for_current_ruby:
+
+  RubyParser.for_current_ruby.parse "1+1"
+  # => s(:call, s(:lit, 1), :+, s(:lit, 1))
+
+== DEVELOPER NOTES:
+
+To add a new version:
+
+* New parser should be generated from lib/ruby_parser[23].yy.
+* Extend lib/ruby_parser[23].yy with new class name.
+* Add new version number to V2/V3 in Rakefile for rule creation.
+* Add new `ruby_parse "x.y.z"` line to Rakefile for rake compare (line ~300).
+* Require generated parser in lib/ruby_parser.rb.
+* Add new V## = ::Ruby##Parser; end to ruby_parser.rb (bottom of file).
+* Add empty TestRubyParserShared##Plus module and TestRubyParserV## to test/test_ruby_parser.rb.
+* Extend Manifest.txt with generated file names.
+* Add new version number to sexp_processor's pt_testcase.rb in all_versions.
+
+Until all of these are done, you won't have a clean test run.
+
+== REQUIREMENTS:
+
+* ruby. woot.
+* sexp_processor for Sexp and SexpProcessor classes, and testing.
+* racc full package for parser development (compiling .y to .rb).
+
+== INSTALL:
+
+* sudo gem install ruby_parser
