Yes it would be. The only two commands in perl are policy (for mast)
and verify. I'd prefer python for both of them. They could be done
with shell scripting, but in our experience, most embedded systems are
using fairly broken/limited awk/sed/sh versions and usually miss auxiliary
commands (dirname, id, etc) to work properly. So these commands tend to not
work on embedded systems anyway.
