So do I.  What about a facility in the Horde framework to provide this; a
Horde function that could be called to check on a mandatory capability,
produce a suitable error message, and exit.  (Could it check on whether
the headers have been sent or not?)  But that way the code to check would
be clean (a one-liner).
