# 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.
