2002-12-29 Sven Neumann <sven@gimp.org> * configure.in * etc/Makefile.am * etc/gimprc.in * etc/gimprc_user.in: removed templates for gimprc files. * etc/gimprc: added this file as generated by gimp-config-dump. * app/gui/user-install-dialog.c * data/misc/user_install: don't install an empty user gimprc. * app/config/Makefile.am * app/config/gimpconfig-substitute.[ch]: removed these files. * app/config/gimpconfig-path.[ch]: and added them again with reduced functionality. Paths found in config files are now basically handled like standard strings by the config system. Users of the GimpConfig path variables need to expand the path themselves. * app/config/gimpbaseconfig.c * app/config/gimpconfig-deserialize.c * app/config/gimpconfig-dump.c * app/config/gimpconfig-utils.c * app/config/gimpconfig.c * app/config/gimpcoreconfig.c * app/config/gimprc.c: * app/base/base.c * app/base/temp-buf.c * app/core/gimp.c * app/core/gimpdatafactory.c * app/core/gimpmodules.c * app/gui/user-install-dialog.c * app/plug-in/plug-in.c * app/tools/tools.c * app/widgets/gimppropwidgets.c: changed accordingly.
