Editor: The PalmOS is really nice, but there are some Things that can only be done by supplementing or bypassing it entirely. Unfortunately, writing a system patch is not an easy thing to do, and there are inherent problems with inter-patch conflicts, as many Mac and PC users are familiar with.
Enter HackMaster. This is a system extension manager for your PalmPilot. It utilizes an open standard for separately-downloadable "Hack" files, and provides the means of managing them. It performs the dirty work of installing and uninstalling the patches, and even maintains a proper chain of Hacks that try to patch the same TraP. It allows you to install and uninstall them in any order, instantly, without restarting (ask your desktop computer to do that!). Plus, it records your currently active set of extensions, and gives you the option of automatically reinstalling them after a Soft Reset.
This is as close to a Revolution in the PalmPilot world as you're likely to see. A number of other third-party developers have already embraced the HackMaster protocol as the system patch method of choice.
