Revision 3229

Second iteration:
- all additional SConscript files reviewed and 'cleaned up'.
- broke compatibility with scons <0.98.1! Why?
   -- 0.98.1 was released April 2008, even Lenny ships 1.0.0
   -- we had a lot of (dirty) workarounds and checks to keep that compatibility
   -- a couple of features in 0.98.1 make life a lot easier (e.g. Glob())
   -- scons is Python-only (no libraries) so very easy to install/update
