DESCRIPTION
This module provides several functions to configure and to maintain an
AFS cell. It is used to maintain the configuration directory. Any
function required must by explicitly listed by the "use" statement to
be exported into the calling package.
Some of these functions have the optional argument FOLLOW. FOLLOW
determines which file should be used should PATH be a symbolic link.
If FOLLOW be set to 1, then the symbolic link is followed to its
target. If FOLLOW is set to 0, then the function applies to the
symbolic link itself. If not specified FOLLOW defaults to 1.
COMPATIBILITY

1.
