"""
   Usage: rebuild-pot.py <product> <path to products dir>

   If you are lazy you can also use atct, atrbw etc. as shorthands and if you
   set your INSTANCE_HOME correctly it will automagically use the right version.

   So 'rebuilt-pot.py atrbw' is a valid shorthand.
   
   At release time, there is also an easy alias 'rebuild-pot.py all' which will
   rebuilt all pot files for all products. You can only use it, if you have
   specified your INSTANCE_HOME.
