| # - Find Ruby |
| # This module finds if Ruby is installed and determines where the include files |
| # and libraries are. It also determines what the name of the library is. This |
| # code sets the following variables: |
| # |
| # RUBY_INCLUDE_PATH = path to where ruby.h can be found |
| # RUBY_EXECUTABLE = full path to the ruby binary |
