#
# = Usage notes =
#
# * You need to have XCode and git installed
# * Builds from current repository, current revision. So you should manually checkout the desired revision to build
# * If no repository found - then  sources fetched into ~/src/synfig and the latest master branch is built
# * Executing script without arguments makes a full clean build and produces dmg package
# * You can pass arguments to the script to invoke particular stage.
#	Available stages: mkmacports, mkdeps, mketl, mksynfig, mksynfigstudio, mkapp, mkdmg
#	Example:
#		synfigstudio-osx-build.sh mkdeps
# * You can pass a custom command to be invoked in the build environment.
#	Example (uninstalls glibmm package from the buildroot):
#		synfigstudio-osx-build.sh port uninstall glibmm
# * If you suspect something is wrong with your macports installation you can always start from scratch by removing ~/src/macports dir

# TODO: Don't build into /tmp/skl
# TODO: Disable 32bit?
