[Scons-users] Deducing dependencies from command lines

Tue Jun 6 12:17:12 EDT 2017

i was looking at it with sconsign, and it's not in there. so I'd imagine it wouldn't turn up with tree=prune (though I hacked things a bit by monkeypatching Scons.Defaults.xxxObjectFile to get an explicit dependency in the build_
