-This file implements the main() function used by the scons script.
-
-Architecturally, this *is* the scons script, and will likely only be
-called from the external "scons" wrapper. Consequently, anything here
-should not be, or be considered, part of the build engine. If it's
-something that we expect other software to want to use, it should go in
-some other module. If it's specific to the "scons" script invocation,
-it goes here.
