That's good.  We actually avoid any binary issues as waf is designed to be 
distributed with the distfiles.  If we need a new version we include it in the 
tarball.  For developers it's trivial to set it up right from the git repo using 
'waf-light' and doing a git pull to update.

I have updated rtems_waf/bsp.py to include all BSPs.  Please note they may not 
work and I have not touched any of the BSPs added in the last year.  If there is 
a BSP you want working let me know.

You only run waf config once, ever.  This sets up config.cfg with the number of 
BSPs you supplied during the first config.  After that you must edit it by hand 
to make changes.  This error is to warn you so you do not delete your config by

Great question.  I suppose patches on the lists are OK for now?
