# Notes on depends:
#	app-arch/deb2targz is for converting the OpenShot program's .deb package
#	dev-lang/swig is for compiling the MLT Python bindings
#	media-libs/mlt is so we don't have to depend on OpenShot's rather
#		large (~22M) .deb dependencies package (we only use 1 file from it)
#	Everything else is required by OpenShot or is an optional/USE feature
