usage: svnbench <subcommand> [options] [args]
Subversion benchmarking tool.

  or 'svnbench --version --quiet' to see just the version number.

on the directories.  If no arguments are supplied to such a
command, it recurses on the current directory (inclusive) by default.

Available subcommands:
   help (?, h)
   null-blame
   null-export
   null-list (ls)
   null-log
   null-info
