CHIPMUNK VERSION 4.1.0 For Ruby
(C) Scott Lembcke

IMPORTANT NOTICE:
This is a fork of Chipmunk 4.1.0 for use with Ruby 1.8.x and 1.9.x. 
The standard version of Chipmunk is only compatible with 1.8.x.
The standalone library of Chipmunk will not be not maintained in 
this branch, at least not for now. 

(1) 1/10/09 Cross-Platform Gem built by John Mair (banisterfiend)
    * Just go: gem install chipmunk  

(2) Patched for 1.9.1 by Beoran (beoran@rubyforge.org)

(3) How to build the gems? (maintainers only)
    * Install rake-compiler (http://github.com/luislavena/rake-compiler)
    * Install 1.9.1 and 1.8.6 mingw ruby versions (instructions above)
    * Type: rake cross native gem RUBY_CC_VERSION=1.8.6:1.9.1
    * Upload new gems to rubyforge and gemcutter.

CHANGES SINCE RELEASE 3:

  * Rational versioning scheme: (major.minor.build) Small changes
    increment the build number. Significant changes that don't affect
    backwards compatibility increment the minor number. Major changes
    that will break backwards compatibility will increment the major
    number.

  * Optimizations: Speed increases of 5-10% should be common.

  * Groove Joint: Similar to a pivot joint, but one of the anchors is
    on a linear slide instead of being fixed.

  * Comments/cleanup. The code should be much more readable now.

  * Official build paths for working on Linux and MSVC.
