smupcheck, which stands for Smart Update Checker, checks Web sites for updates automatically, even if they don't offer an RSS feed. It is a very basic tool, and does not offer advanced features such as checking password-protected Web sites, highlighting changes, or filtering results.
h300goodies consists of a handful of Perl and shell scripts that were written to help manage a user's music collection on an iRiver H320 or H340 digital jukebox. These scripts don't run on the player natively, but are used when the player is mounted on a local file system via a USB connector. The scripts will build M3U playlists that you define, scan your collection and build playlists based on the genre in the MP3/Ogg file ID3 tags, scan your collection for long filenames that cause problems with iRiver's database software, randomize an existing M3U playlist, and so on.
