[Scons-dev] How to traverse the graph after files are read

[anatoly techtonik]

Hi,

I am trying to get SCons build graph after files
are read, but before the processing is started.

I want it to be an alternative to build process
and interactive mode:
https://bitbucket.org/scons/scons/src/95b566e4baf0253e1b36b8a9e00a97cd84d22566/src/engine/SCons/Script/Main.py?at=default#cl-1091

How to start traversing nodes without building?
