[Scons-users] Get a list of emitted targets from the previous run

[Erik Kazandjian]

Hi Bill

I'm parsing in process using the pyang library. The reason for parsing in
the emitter phase is because other files include the generated headers. The
generated c++files are given as sources to the library builders.  That's is
why I do this in the emitter phase to declare all files that Will je
generated and get the dependency tree right

Cheers

Erik
