[Scons-users] Chaining generated sources.

[William Blevins]

Bill,

I made a patch which shows test case proof of concept.

The generalized test case fails as I expected, but I would like to make a
stronger test assumption than "test.up_to_date()".  I am a little uncertain
on how to explicitly test against the "nodes" created by env.Java through
the TestSCons instance.

I may be able to write the node information to a file inside the SConstruct
and check the expected with "test.must_contain_exactly_lines", but this
seems round about.  Any thoughts?

V/R,
William
