  <help>
    Splits a pathset according to a regular expression.

    You can have the tool expand the paths in the pathset by a certain number
    of levels prior to testing whether it matches the regular expression.


    **Note**: you can't use '$' in your regular expression. To anchor the
    expression to the end of the path use the checkbox.


    *Note*: the regular expression must match the path from its beginning.
