"""Create a distribution of ANUGA from latest revision

   This script is assumed to be run in the root directory of anuga
   from a working sandpit connected to svn

   It will create a distribution of ANUGA from the version which is
   currently checked out.

   To use the latest version run

     svn up

   before running this script. To use a specific revision (2187, say) run

     svn up -r 2187

   first assuming that create_distribution.py (this script) and anything
   it depends on still work for that revision.

   This script works only on Linux
