So, I need to extract the Version and Build numbers from the Chicken
banner.  The banner as given by "chicken -version" is:

$ chicken -version

  /       (/      _ (/_   _ __
 /        / )__(_(__/(___(/_/ (_
(______)
Version 2, Build 3 - windows-mingw32-x86 - [ dload ptables ]
(c)2000-2005 Felix L. Winkelmann


So how do I write a regular _expression_ to rip out the "2" in "Version
2," and the "3" in "Build 3" ?  For simplicity this can be 2 different
regular expressions, it doesn't have to be done in 1 go.  I'm reading
various regex howtos, but there's a learning curve and if anyone knows
how to do it off the top of their head, I'd learn faster.  :-)

    

How about:

% csi -ne '(print (chicken-version))'
Well, I'm not assuming csi is available.  I look for chicken-static.exe and then chicken.exe.

Part of my problem was that CMake didn't take \d, it wanted [0-9]+.  But parentheses still don't seem to work.  I've bugged the CMake guys about it, and meanwhile I've worked around the problem by doing a double regex.

I can now find a previous Chicken installation; next question is what to do with it.
