NAME
    regexp - match a regular expression

    SYNOPSIS
    string *regexp(string *array, string pattern)

    DESCRIPTION
    Regexp is short for regular expression and it is a general way of matching string used frequently in unix. The funcion regexp in lpc tries to match all strings in the array against a regular expression contained in the string exp and return all strings that matched. This function can sometimes replace a filter_array() operation and should do so as it is much faster. Here is a short summary of regexps. 

    	ONE CHAR MATCHES:
	'c'	Matches the character c.
	'.'	Matches any character.
	'[abc]'	Matches one of the characters a, b or c.
	'[^ab]' Matches any character _but_ a or b.

	MULTIPLE CHAR MATCHES: ( 'c' can be any of the one char matches. )
	'c*'	Matches a sequence of zero or more of the character c.
	'c+'	Matches a sequence of one or more of the character c.

	MISC
