I wouldn't quite bother yet.  unsermake still requires automake AFAIK so 
unless we manage to separate it from that dependency it wouldn't be 
horrifically useful.

It might not be hard to do so however and make it depend on cmake or something 
instead. :)

It would be very nice to get unsermake to work though.  It's output is much 
nicer than make's (although it is certainly possible to get make to output 
the same I suppose), and it supports parallel compilation better.

Also, I believe the really useful part of --compile-jobs=, which no one seems 
to have brought up yet, is that directories full of man pages will break 
under parallel compilation as the build rule seems to involve outputting a 
temporary file with a set name and then renaming the temp file to the correct 
file name.

e.g. maninput-foo -> temp.1 -> foo.1

So when trying to convert multiple files to a man page simultaneously, things 
sometimes would break.

Of course if cmake's build rule is improved in that regard then it's probably 
not a problem.
