Portable Gimp places the Gimp(GNU Image Manipulion Program) with its configuration files in a folder to utilize it without installation in the Puppy space(pupsave).
The Gimp is a large application. The Gimp makes large cash and saves new brushes and patterns consuming your pupsave.
The Portable Gimp has the Gimp code as a sfs, and mounts the sfs and launch. The sfs is unmounted at the application finished so that the loop back devices to be free. The Portable Gimp also holds the Gimp settings, cache and additionals in the same 'gimp-portable' folder, not to consume your pupsave.
Tested on Precise-571JP and on TahaPup 6.0.5 CE. Works on Precise Puppy and TahrPup.
