In my mailbox this AM was a reply from the author of compface saying that he
doesn't have the time to look after the compface routines right now, and that
{un,}compface were intended as "sample" sources to show how to use the library.

See below an initial stab (it was not intended for distributiuon -- I was
expecting James to sanitize it when merging with the master sources!).
The effect of this is that the requirement for "ikon2xbm" (and hence pbmplus,
and all those extra processes, etc) disappears ...

Here are the patches to uncompface to allow it to take "-X" ...
