This leads to one of the advantages of SCons: because you have a "proper" 
language you can reduce your dependence on commands.

For instance, I've just changed a bit of the Rekall build system that used 
"sed" cos I wan't it to run under Windows (directly, not via Cygwin) and 
"sed" isn't there. So I just recoded it to do the processing in python. Took 
about 30minutes. Probably quick if I'd not had a beer beforehand:)
