I don't pretend to understand all the cross-platform issues and I was 
trying to avoid work :-)

OK, I'll do a very basic page "Show Application Title, Version, and 
Company" i.e. similar to the existing one that somebody's filled with 
code- I don't want to mess around with that until we know where it came 
from.

Somebody was asking about getting version info into the final (i.e. 
executable) filename. I've put date info into filenames on Linux using 
Compilation -> Execute After -> Command (with mv, `date` and so on) but 
if access to the IDE-generated version info is now settling down 
presumably it wouldn't be too difficult to read it out as the final 
stage of the build process- even if this takes a separate 'brand' program.

I suppose the next question is going to be how to sign an executable so 
that collaborating programs can check each others' authenticity. I 
believe that ELF doesn't have provision in the header for anything like 
that, but presumably it could be stuck into the resource info e.g. in 
the FileDescription field.
