=head1 NAME
-parse-wormedit - WormEdit level data parser
+parse-wormedit - Wormy level data parser
=head1 SYNOPSIS
- parse-wormedit [--raw] <input.lvl>
+ parse-wormedit [--raw|--render] [--output <file.ext>] <input.lvl>
=head1 DESCRIPTION
-Reads WormEdit v0.53 levels from STDIN or given file,
-and outputs contents, summarised or in full.
+Reads Wormy levels (either original WormEdit source or compiled TI-86 string)
+from STDIN or given file, and prints summarised contents to STDOUT.
+
+If an I<output> file name is given, its extension determines the format.
