# Run from any folder to build

# - any local folder (using the -p option)
# Will build a binary archive (tar.bz2 / zip) and source archive.
# The source archive won't be built for local builds. Trunk and

# If the required Qt installation isn't in PATH use --qmake option.

#
# requires python which package (http://code.google.com/p/which/)
