[Python-checkins] CVS: distutils/distutils/command build.py,1.28,1.29

[Greg Ward]

Update of /cvsroot/python/distutils/distutils/command
In directory slayer.i.sourceforge.net:/tmp/cvs-serv7503

Modified Files:
	build.py 
Log Message:
Changed to use the 'sub-commands' machinery: 
  - added 'sub_commands' class attr
  - added 'has_*()' predicates referenced by the sub-command list
  - rewrote 'run()' so it's a trivial loop over relevant sub-commands
