5 Architecturally, this *is* the scons script, and will likely only be
6 called from the external "scons" wrapper. Consequently, anything here
7 should not be, or be considered, part of the build engine. If it's
8 something that we expect other software to want to use, it should go in
9 some other module. If it's specific to the "scons" script invocation,
10 it goes here.
