-parse-wormedit - WormEdit level data parser
+parse-wormedit - Wormy level data parser
=head1 SYNOPSIS
- parse-wormedit [--raw] <input.lvl>
+ parse-wormedit [--format=<type>] [--levels=<number>] [--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 parsed data to STDOUT.
+
+If an I<output> file name is given, its extension determines the format,
+otherwise explicitly given by the I<format> option:
+
+=over 6
+
+=item txt
+
+Plain text summary of levelpack contents.
+
+=item yaml
+
+All parsed data in YAML syntax.
+
+=item json
+
+Parsed data in JSON syntax.
+
+=item pnm, png, bmp, ...
+
+Image drawing of rendered levels.
+Unrecognised values are interpreted as file type and converted by Imager.
