"""
Line Counter
~~~~~~~~~~~~

Count the lines in given files.

Multiple patterns with shell-style wildcards (``*`` for
everything, ``?`` for any single character) are accepted.

Example usage and output::

    $> python linecounter.py /some/path *.php *.html *.css

    *.css:      982 lines
    *.py:     4.739 lines
    *.xhtml:  2.218 lines
    ---------------------
    total:    7.939 lines

It returns the total for each pattern and an overall total.

Be aware that files will be included multiple times if you
specify overlapping patterns and so the result might not be
what you expected.

Python 2.5 is required.
