This module contains partial re-implementations of FilePath, pending some
specification of formal interfaces it is a duck-typing attempt to emulate them
for certain restricted uses.

See the constructor for ZipArchive for use.

        Return a new ZipPath representing a path in C{self.archive} which is
        a child of this path.

        @note: Requesting the C{".."} (or other special name) child will not
            cause L{InsecurePath} to be raised since these names do not have
            any special meaning inside a zip archive.  Be particularly
            careful with the C{path} attribute (if you absolutely must use
            it) as this means it may include special names with special
            meaning outside of the context of a zip archive.
