# - 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
