    25 # This module is a simple facade to the functionality used by the

    26 # style package that comes from WebKit modules outside the style

    27 # package.

    28 #

    29 # With this module, the only intra-package references (i.e.

    30 # references to webkitpy modules outside the style folder) that

    31 # the style package needs to make are relative references to

    32 # this module. For example--

    33 #

    34 # > from .. style_references import parse_patch

    35 #

    36 # Similarly, people maintaining non-style code are not beholden

    37 # to the contents of the style package when refactoring or

    38 # otherwise changing non-style code. They only have to be aware

    39 # of this module.
