def main():
    '''Filter sql test case output using pcre expressions.

    The program expects to find a file in the ./patterns directory
    named with the test's name.  This file contains text and pcre
    patterns, the pcre patterns being distinguished from the text
    by being enclosed in delimiters, $$ being the default delimiter.

    The pattern file is used as a template to filter stdin.  Text
    outside of the delimiters must match stdin exactly.  Stdin
    matching the pcre patterns is filtered, not sent to stdout but
    replaced with the replacement text, which is the empty string by default.
    Should either the text in the pattern file or any pcre expression
    fail to match all of stdin is copied to stdout.

    On error nothing is sent to stdout.'''
