{-| HsConstants contains the Haskell constants

This is a transitional module complementary to 'Ganeti.Constants'.  It

is intended to contain the Haskell constants that are meant to be

generated in Python.

Do not write any definitions in this file other than constants.  Do

not even write helper functions.  The definitions in this module are

automatically stripped to build the Makefile.am target

'ListConstants.hs'.  If there are helper functions in this module,

they will also be dragged and it will cause compilation to fail.

Therefore, all helper functions should go to a separate module and

imported.
