def extract_from_dir(dirname=os.getcwd(), method_map=DEFAULT_MAPPING,
                     options_map=None, keywords=DEFAULT_KEYWORDS,

    """Extract messages from any source files found in the given directory.

    This function generates tuples of the form:

        ``(filename, lineno, message, comments)``

    Which extraction method is used per file is determined by the `method_map`
    parameter, which maps extended glob patterns to extraction method names.
    For example, the following is the default mapping:

    >>> method_map = [
    ...     ('**.py', 'python')
    ... ]

    This basically says that files with the filename extension ".py" at any
    level inside the directory should be processed by the "python" extraction
    method. Files that don't match any of the mapping patterns are ignored. See
    the documentation of the `pathmatch` function for details on the pattern
    syntax.

    The following extended mapping would also use the "genshi" extraction
    method on any file in "templates" subdirectory:

    >>> method_map = [
    ...     ('**/templates/**.*', 'genshi'),
    ...     ('**.py', 'python')
    ... ]

    The dictionary provided by the optional `options_map` parameter augments
    these mappings. It uses extended glob patterns as keys, and the values are
    dictionaries mapping options names to option values (both strings).

    The glob patterns of the `options_map` do not necessarily need to be the
    same as those used in the method mapping. For example, while all files in
    the ``templates`` folders in an application may be Genshi applications, the
    options for those files may differ based on extension:

    >>> options_map = {
    ...     '**/templates/**.txt': {
    ...         'template_class': 'genshi.template:TextTemplate',
    ...         'encoding': 'latin-1'
    ...     },
    ...     '**/templates/**.html': {
    ...         'include_attrs': ''
    ...     }
    ... }

    :param method_map: a list of ``(pattern, method)`` tuples that maps of
                       extraction method names to extended glob patterns

    :param keywords: a dictionary mapping keywords (i.e. names of functions

                     tuples that specify which of their arguments contain
                     localizable strings
    :param comment_tags: a list of tags of translator comments to search for
                         and include in the results
    :param callback: a function that is called for every file that message are
                     extracted from, just before the extraction itself is
                     performed; the function is passed the filename, the name
                     of the extraction method and and the options dictionary as
                     positional arguments, in that order
    :param strip_comment_tags: a flag that if set to `True` causes all comment
