# USAGE NOTES:
#
# This script is meant to be used as follows:
#   user@host ~ $ ./build_bundle.sh ~/tmp 0.3.2 ~/tmp/0.3.1/Bitmask-linux64-0.3.1/ /media/Shared/CHANGELOG ~/tmp/bundle_out/
#
# So we would have:
#    REPOS_ROOT      -> ~/tmp
#    VERSION         -> 0.3.2
#    TEMPLATE_BUNDLE -> ~/tmp/0.3.1/Bitmask-linux64-0.3.1/
#    JOINT_CHANGELOG -> /media/Shared/CHANGELOG
#    DEST            -> ~/tmp/bundle_out/
#
# We need to set different PATHs in order to use a specific version of PySide,
# supposing that we have our compiled pyside in '~/pyside/sandbox', the above command would be:
#   user@host ~ $ PYTHONPATH=~/pyside/sandbox/lib/python2.7/site-packages/ LD_LIBRARY_PATH=~/pyside/sandbox/lib/ PATH=$PATH:~/pyside/sandbox/bin/ ./build_bundle.sh ~/tmp 0.3.2 ~/tmp/0.3.1/Bitmask-linux64-0.3.1/ /media/sf_Shared/CHANGELOG ~/tmp/bundle_out/
