#  run_tests.py:  test suite for cvs2svn
#
#  Usage: run_tests.py [-v | --verbose] [list | <num>]
#
#  Options:
#      -v, --verbose
#          enable verbose output
#
#  Arguments (at most one argument is allowed):
#      list
#          If the word "list" is passed as an argument, the list of
#          available tests is printed (but no tests are run).
#
#      <num>
#          If a number is passed as an argument, then only the test
#          with that number is run.
#
#      If no argument is specified, then all tests are run.
#
#  Subversion is a tool for revision control.
