CLIENT_HARD_FORK_POINT
    
    this is an empty commit, with the purpose of indicating the fork point,
    at which the '2011-05-30' state of the 'h-client' code in the 'h-source' SVN tree,
    was used as the base of a new distinct 'h-client' SVN tree on 2011-06-01
    
    all commits below this one were made to the 'h-source' repo,
    and all commits above to this one were made to the 'h-client' repo,
    which had the original code, but did not retain the commit history
