# This script allows you to create a Universal Binary of VLC.app. It requires
# pre-compiled binaries for Intel-, Intel64- and PowerPC-based Macs; no sources.
# PPC64 is not supported right now, but could be added with little effort.
# Using different OS X SDKs for both platforms is absolutely fine of course.
# All you need to do is CHANGE THE ROOTS and READ THE COMMENTS.
# Happy releasing!

# INTELROOT == path to VLC.app compiled on an Intel-based Mac (e.g. jones).
# INTEL64ROOT == path to VLC.app compiled in 64bit mode (e.g. on jones with -m64).
# PPCROOT   == path to VLC.app compiled on a PowerPC-based Mac (e.g. veda).
# PPCROOT=/Volumes/vlc-1.0.2/VLC.app
# Note that these roots only require read-access and won't be changed at all.

# UBROOT    == path to a VLC.app bundle which will contain the Universal Binary.
