please note that the normal detection of implicit dependencies, e.g. 
Header files (*.h/*.hpp) for C++ projects, works "out-of-the-box" in SCons.

Viktor puts special requirements on his build process, that's why some 
hacking is necessary. If you follow standard C/C++ project setups, there 
shouldn't be anything in your way. Just try SCons out on a very simple 
project, maybe you have a few files/folders that are currently 
controlled by make/autotools.
If you get stuck while rewriting stuff, please ask your questions right 
here and let us help you out.

Best regards,

Dirk
