## returns list of file names.The expand function builds a list of file names in alphabetical order that matches the pattern pat. The pattern is tokenized using / as a delimiter.
match:fn(pat, name: string): int;
## returns 1 on match; 0 if no match.The match function returns 1 if it matches the pattern pat. Otherwise, it returns 0.
The pat passed to match and each token of pat passed to expand may include combinations of the special characters *, ?, [, and ].
The asterisk * matches a string of zero or more characters.
The query ? matches any single character.
The notation [s], where s is a non-empty string, matches any single character in s. A range of characters can be expressed by a string s of the form cstart-cend. The notation [^s], where s is a non-empty string, matches any single character not in s. The characters *, ?, and [ lose their special meaning if they occur in s.
If any character is preceded by the character \, that character loses any special meaning and is interpreted literally.
