"""
This is a version of `MiscUtils.Configurable.Configurable`
that provides a customized `setting` method for classes which
have a `serverSidePath` method. If a setting's name ends with
``Filename`` or ``Dir``, its value is passed through
`serverSidePath` before being returned.
In other words, relative filenames and directory names are
expanded with the location of the object, NOT the current
directory.
Application and AppServer are two well known users of this
mix-in. Any class that has a `serverSidePath` method and a
`Configurable` base class, should inherit this class instead.
This is used with for MakeAppWorkDir, which changes the
serverSidePath.

Returns the setting, filtered by
self.serverSidePath(), if the name ends with
``Filename`` or ``Dir``.
