iPup is a simplified build of Puppy Linux by Todd Richardson for use in institutional settings. iPup's applications are limited to those typically used in libraries and schools. iPup comes with AbiWord, Firefox, gFTP and mtPaint.

The purpose behind building iPup has been to create a puplet (custom build of Puppy) that is easy for novice users to understand (at least when it comes to getting on the Internet or typing a paper), but not too user friendly when it comes to things like mounting flash drives, CD-ROM's and the like. Instant messaging, CD ripping software and media players have not been included. Having said this, most, but not all, of the library files found in the standard version of Puppy have also been included in iPup. This allows you to add software with minimal headache.
