# Copies the regular distribution of the gstreamer framework
# into the libs directory (to be used for creating the Mac OS
# bundle). It also prunes unnecessary files and relocates the
# dynamic libraries.
#
# This script is run by the build process and should not be
# executed manually.
#
# Usage: $script [framework destination path] [app bundle path] [qgc executable name]
#
# destination is usually: ../libs/lib/Frameworks/
# app bundle is something like: /path/qgroundcontrol.app
# executable name is usually: qgroundcontrol
