	#  in test/regression with +filename+. When +create+ is +true+ the file
	#  will be created/overwritten. Otherwise it is tested against returning
	#  whether it has equal or not. When a test fails both test file and new
	#  file exist in the regrssion directory - so you can execute a diff.

	#  Example:
	#    RegressionTest.test `#{cfrubybin} --help`,'cfruby_helptext',$test_create
