## This module contains basic filesystem types and interfaces. This
## includes:
## <ul>
##	<li>The concept of different file types including basic
##	files, mount points, tmp files, etc.</li>
##	<li>Access to groups of files and all files.</li>
##	<li>Types and interfaces for the basic filesystem layout
##	(/, /etc, /tmp, /usr, etc.).</li>
## </ul>
## </p>

## <required val="true">
##	Contains the concept of a file.
##	Comains the file initial SID.
