For adding releases
Userscripts generally only work under Firefox with the Greasemonkey extension. Google Chrome support can be very hit-or-miss, Opera compatibility is very sparse. Script compatibility under Google Chrome is greatly increased when using the TamperMonkey extension.
Bandcamp, Beatport, and Local File Parsers (with great assistance comes great responsibility)
These parsers are meant to be run at the command line passing in either a URL (Bandcamp release, or Beatport release), or a directory with a set of files. The local file parsers run on all files in a directory with the same extension, and are intended to output a whole release, suitable for copying / pasting into the tracklist page's Track Parser. They are written in Perl, and require Audio::Scan, and at least Perl v5.10. The local file parsers are also currently format specific.
