+"""SCons.Script
+
+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.
