Agreed, such as --help or --version output. However it looks as though 
it's important to check anything that attempts this on e.g. the system 
text-mode console or over something really crude like telnet... and I 
hope you're doing that for fpGUI since you keep telling us how good it 
is :-)

I think it could probably be done by slipping a unit in just before 
cthreads, provided that this terminated aggressively. That's actually 
less intrusive that the editing I've been doing in the .lpr 
initialisation block, but it would mean splitting out e.g. text-mode 
--help and graphics-mode --about into separate places.
