-# NOTES FOR UPDATING PORT:
-#
-# We use tarballs from the *stable* branch of the upstream git repository.
-#
-# X264_BUILD is the "core" number, and can be found in x264.h.
-#
-# X264_REV requires a checkout the git revision for the version the port
-# is being updated to. Then run version.sh against it.
-#
-# Bumping PORTREVISION for dependent ports? This is useful:
-#   fgrep -lr --include='*/Makefile*' :multimedia/libx264 $PORTSDIR |
-#   sed 's,/Makefile.*,,' | xargs $PORTSDIR/Tools/scripts/bump-revision.sh
-# or
