# tree2test.py - turn a directory tree into TestSCons code
#
# A quick script for importing directory hierarchies containing test
# cases that people supply (typically in a .zip or .tar.gz file) into a
# TestSCons.py script.  No error checking or options yet, it just walks
# the first command-line argument (assumed to be the directory containing
# the test case) and spits out code looking like the following:
#
#       test.subdir(['sub1'],
#                   ['sub1', 'sub2'])
#
#       test.write(['sub1', 'file1'], """\
#       contents of file1
#       """)
#
#       test.write(['sub1', 'sub2', 'file2'], """\
#       contents of file2
#       """)
#
# There's no massaging of contents, so any files that themselves contain
# """ triple-quotes will need to have their contents edited by hand.
