# Some tests for the library:
#	lines starting with # are comments
#	lines starting with / are a regular expression pattern
#		The pattern must end with / and may be followed by:
#			i -> ignore case
#			n -> create newline sensitive regex
#	lines starting with > are a string input to the last pattern
#		To test newline sensitive matching, add \n to the string.
#	lines starting with a number are the expected result
#		If more than one line, every subsequent line is the
#		value of an "subresult".
#	:NOMATCH means that the string input should not match
