Bug 1390916 - Always use --track instead of --no-remove for install manifests; r=gps The --track flag provides a more accurate accounting of what files were installed by the manifest, so they can be appropriately removed. For example, test files are now removed from _tests if an entry in a test file is deleted. The --no-remove flag is removed as an alternative, and the --track flag is now mandatory.

#!/bin/bash
# this script creates a wrapper shell script for an executable.  The idea is the actual executable cannot be
# executed natively (it was cross compiled), but we want to run tests natively.  Running this script
# as part of the compilation process will move the non-native executable to a new location, and replace it
# with a script that will run it under qemu.
