# ===================================================
# 
# This script will install a version of ruby-1.9.2-p180 for [rbenv][] that's 
# patched with RVM's [gcdata][] patch.
# 
# CAVEAT
# ------
# 
# Keep in mind that this is for **ruby-1.9.2-p180**. Update the version numbers 
# for whichever Ruby you're using. You'll also want to make sure the versions 
# for the supporting libraries are correct, too. For guidance, take a look at 
# the appropriate [ruby-build script][].
