= CodeRay - Trunk folder structure
== bench - Benchmarking system
All benchmarking stuff goes here.
Test inputs are stored in files named <code>example.<lang></code>.
Test outputs go to <code>bench/test.<encoder-default-file-extension></code>.
Run <code>bench/bench.rb</code> to get a usage description.
Run <code>rake bench</code> to perform an example benchmark.
== bin - Scripts
Executional files for CodeRay.
== demo - Demos and functional tests
Demonstrational scripts to show of CodeRay's features.
Run them as functional tests with <code>rake test:demos</code>.
== etc - Lots of stuff
Some addidtional files for CodeRay, mainly graphics and Vim scripts.
== gem_server - Gem output folder
For <code>rake gem</code>.
== lib - CodeRay library code
This is the base directory for the CodeRay library.
== rake_helpers - Rake helper libraries
Some files to enhance Rake, including the Autumnal Rdoc template and some scripts.
== test - Tests
Tests for the scanners.
Each language has its own subfolder and sub-suite.
Run with <code>rake test</code>.

coderay foo.rb > foo.html # HTML page output to file, based on extension
coderay -ruby < foo.rb # colorized output to terminal, based on lang
coderay -ruby -loc < foo.rb # print LOC count, based on lang
