This is version 0.99.31 of the GNU Image Manipulation Program. This version is no longer distributed along with the Gtk toolkit; you'll have to grab and install it separately. Please install Gtk before configuring the GIMP for compilation. This GIMP requires GTK 1.0.1 or later. gimp-data-extras contains a bunch of optional extra data files for GIMP. See the files README and NOTES in the archive for more details.
