   3  This file implements the main() function used by the scons script. 
   4   
   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.
