* Gimptool rewritten in C, originally for Win32, where end-users who
* might want to build and install a plug-in from source don't
* necessarily have any Bourne-compatible shell to run the gimptool
* script in. Later fixed up to replace the gimptool script on all

*
* Yes, this program leaks dynamically allocated strings without
* hesitation. So what, it runs only for a minimal time.

Usage: gimptool-2.0 [OPTION]...\n\

General options:\n\
--help print this message\n\
--quiet, --silent don't echo build commands\n\
--version print the version of GIMP associated with this script\n\
-n, --just-print, --dry-run, --recon\n\
don't actually run any commands; just print them\n\
Developer options:\n\
--cflags print the compiler flags that are necessary to\n\
compile a plug-in\n\
--libs print the linker flags that are necessary to link a\n\
plug-in\n\
--prefix=PREFIX use PREFIX instead of the installation prefix that\n\
GIMP was built when computing the output for --cflags\n\
and --libs\n\
--exec-prefix=PREFIX use PREFIX instead of the installation exec prefix\n\
that GIMP was built when computing the output for\n\
--cflags and --libs\n\
--msvc-syntax print flags in MSVC syntax\n\
\n\
Installation directory options:\n\
--prefix --exec-prefix --bindir --sbindir --libexecdir --datadir --sysconfdir\n\
--sharedstatedir --localstatedir --libdir --infodir --mandir --includedir\n\
--gimpplugindir --gimpdatadir\n\
\n\
The --cflags and --libs options can be appended with -noui to get appropriate\n\
settings for plug-ins which do not use GTK+.\n\
\n\
User options:\n\
--build plug-in.c build a plug-in from a source file\n\
--install plug-in.c same as --build, but installs the built\n\
plug-in as well\n\
--install-bin plug-in install a compiled plug-in\n\
--install-script script.scm install a script-fu script\n\
\n\
--uninstall-bin plug-in remove a plug-in again\n\
--uninstall-script plug-in remove a script-fu script\n\
\n\
The --install and --uninstall options have \"admin\" counterparts (with\n\
prefix --install-admin instead of --install) that can be used instead to\n\
install/uninstall a plug-in or script in the machine directory instead of a\n\
user directory.\n\
\n\
For plug-ins which do not use GTK+, the --build and --install options can be\n\
appended with -noui for appropriate settings. For plug-ins that use GTK+ but\n\
not libgimpui, append -nogimpui.\n");
