                ruby-1.9.3-p125 cumulative performance patch.
              
          
    Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84).
Huge thanks to funny-falcon for the performance patches.
