GDAL RubyMakefile for Ruby 1.9.x SWIG bindings
# This makefile generates 4 Ruby extensions - one each for
# gdal, ogr, osr, and gdalconstants. There are two important
# things to note:
#
# * It makes multiple calls to Ruby to discover the Ruby version,
# location of header files, libraries, etc. Thus Ruby must
# be on your path.
#
# * By convention Ruby method names are lower case with underscores,
# thus methods such as "GetFieldName" need to be mapped to
# "get_field_name." This is done by running the separate
# RenamesMakefile.mk script.
