We should consider separating the compile / run front-ends into
separate programs entirely, perhaps by promoting and renaming stpd
("staprun")?  This makes sense further because we will want to make it
possible to install only a small subset of systemtap itself on a
deployment machine in order to run a pre-compiled script.

Actually, not really, with getopt.  A flag must or must not take a parameter,
otherwise it leads to parsing ambiguities.
