Barrys Pet Page
Pets are tarballs, just like '.tar.gz' files, with a md5sum appended on the end. The in-built md5sum is handy, as the file can be checked for integrity after being downloaded. They are used for packaging programs designed or compiled for Puppy and provide desktop icons, menu info etc specific to Puppy
Pets install to a fixed location. They have no dialogs, and so can also be installed without X.
