+    Mangle an absolute filename when the file happens to be in a

+
+      <dotted package name>/<base filename>.
+
+    For example, let's take Five's configure.zcml as an example.  We
+    assemble it in an OS-independent way so this test works on all
+    platforms:

+      >>> def filesystemPath(*elements):

+
+    We see that the filename is now mangled:

+      ...     '', 'path', 'to', 'Products', 'Five', 'configure.zcml'))
+      'Products.Five/configure.zcml'
+
+    The name of a file that's not in a package is returned unchanged:
+
+      >>> not_in_a_package = filesystemPath('', 'path', 'to', 'configure.zcml')
