=================

Invocation::
	``$0 <command>``

The file "user.env" is sourced from the current directory. Use it to set
environment specific defaults. For config variables see the start of this script
and any "$<XXXX>" in the "params" array of any command in test_data.yaml
Some variables to note
	- VERBOSE : make the script output more info.
		VERBOSE=$VERBOSE
	- TS_ROOT : Root directory of the TS repo.
		TS_ROOT=$TS_ROOT
	- NUMBER_OF_PROCESSORS: number of processors in the system. Used for setting the number of
		parallel processes during build
		NUMBER_OF_PROCESSORS=$NUMBER_OF_PROCESSORS

Available commands:
	""      - no command/default -> run all test cases
	clean   - remove build directories
	help    - print this text
	<test case> - run a single build
		available test cases:
