# runtest - run an xmlformat test

# Test scripts are located in ./tests, and are run by naming the basename
# of the input XML file. For example, to run the test for tests/abc.xml,
# invoke "runtest abc".

# The test name "all" runs all tests.

# -p = use ./xmlformat.pl rather than xmlformat.rb
# -r = use ./xmlformat.rb (which is the default anyway)
# -u = update the expected-result file from the actual output file
# -v = verbose
