Yes I will at some stage - just thinking of how to reply to Stephen's
email on the subject and checking what ones I've already submitted to
libselinux/utils. I have a number of these little
utils/samples/examples that I use to test various bits of
libsepol/libselinux and submit those I use to test my patches.

Before I submit any I'll take your suggestion into acount. All ideas
welcome.
