Just be aware that there's a preference file for each configuration profile
in Wireshark, and I don't believe there's a way for Lua to determine the
active Wireshark profile. Plus, the user may choose to override preferences
from the command line with the -o flag, and these overrides are not written
to the preferences file (thus not detectable in Lua); but the -o flag is
probably an advanced feature that most users don't use (or even know
about), so perhaps that's a non-issue.
