# Find Ruby
6+
#
7+
# This module finds if Ruby is installed and determines where the
8+
# include files and libraries are. Ruby 1.8, 1.9, 2.0 and 2.1 are
9+
# supported.
10+
#
11+
# The minimum required version of Ruby can be specified using the
12+
# standard syntax, e.g. find_package(Ruby 1.8)
13+
#
14+
# It also determines what the name of the library is. This code sets
15+
# the following variables:
16+
#
17+
# ``RUBY_EXECUTABLE``
18+
# full path to the ruby binary
19+
# ``RUBY_INCLUDE_DIRS``
20+
# include dirs to be used when using the ruby library
21+
# ``RUBY_LIBRARY``
22+
# full path to the ruby library
23+
# ``RUBY_VERSION``
24+
# the version of ruby which was found, e.g. "1.8.7"
25+
# ``RUBY_FOUND``
26+
# set to true if ruby ws found successfully
27+
#
28+
# Also:
29+
#
30+
# ``RUBY_INCLUDE_PATH``
31+
# same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it
