One word of warning I should have mentioned: if you get a release of
MMDF up to and including release 43 that supports .forward files via the
DOTFORWARD configuration DO NOT use this feature, as it opens a major
security hole.  This problem does not occur in SCO's current MMDF or
the release 43 that they will be shipping.  Hopefully, releases after
43 will fix this (the fix is non-trivial; the easiest solution is to
remove the option).
