"""Driver program to test METAL and TAL implementation.

Usage: driver.py [options] [file]
Options:
    -h / --help
        Print this message and exit.
    -H / --html
    -x / --xml
        Explicitly choose HTML or XML input.  The default is to automatically
        select based on the file extension.  These options are mutually
        exclusive.
    -l
        Lenient structure insertion.
    -m
        Macro expansion only
    -s
        Print intermediate opcodes only
    -t
        Leave TAL/METAL attributes in output
    -i
        Leave I18N substitution strings un-interpolated.
    -a
        Enable source annotations
