[Scons-users] Scons understanding existing project

Thu Aug 4 15:44:35 EDT 2016

Pietro,

SCons handles that internally by calling SCons,Util,flatten(), so you could
use this directly in those cases. As Dirk has already mentioned, scons
--tree=<option> <target> will give you the entire dependency tree for said
target which may be much more useful (depending).

V/R,
William
