If channel will reliably be set, you can just remove the major and minor
checking here.

I thought about removing it, but it doesn't hurt if we keep it and this change
isn't in all channels (though we'll merge it over at some point).

     print 'Error: Do not run this script from a bleeding_edge checkout.'
     return -1
