test of autoprogram with load_into_counting

Not ready for merging.

Procedure:
1) rename script to use underscores instead of dashes
2) make argparse building to a function
3) move documentation from doc/scripts.txt to the tool's argparse. Make a pre-formatted epilog if needed using any ReStructuredText you want to.
