Sorry Robert, there is one more issue here. You're doing "do_%s*" but
this can match multiple tasks, e.g. do_package* would also wipe out
do_package_write_ipk, do_package_write_rpm etc.
The easiest way to handle this is probably in the for loop, making sure
that do_<task>. or do_<task>_setscene. are in the filename.
It might be worth putting some comments in the code about these
subtleties.
Cheers,
Richard
