4.0 engine as an executable shell/cgi

[Bernard Devlin]

The 4.0 engine does not work from a command line at all i.e. as a
shell script processor (at least I can get no output from it).
Somewhere (maybe it was in the text file about the engine) it states
that this new lack of functionality was a side-effect of enabling the
engine to produce revlets.  Seems like a strange explanation, but
there you go...

It means anyone who does use that kind of functionality should keep
old copies of Rev around.  And with Rev version 4+ it will no longer
be possible to use Rev as a cgi program.  Has the apache module been
released so that Rev can be used on one's own server?
