2003-11-04 Sven Neumann <sven@gimp.org> * etc/Makefile.am * etc/gtkrc_user: renamed to gtkrc. * gimp.spec.in: changed accordingly. * app/gui/user-install-dialog.c: don't install the sessionrc, templaterc and unitrc into the personal gimp directory. The files are created when GIMP is quit. * app/core/gimp-templates.c * app/core/gimp-units.c * app/gui/session.c: load sessionrc, templaterc and unitrc from the systemwide config directory. That way you can restore the default setup by removing the respective files from your personal gimp directory.
