Ampersand modules
-----------------

   A module definition can refer to other modules by including
`&MODULE' in its definition.
     MNAME [ options ] &MODULE...

   Then getting the module creates a subdirectory for each such module,
in the directory containing the module.  For example, if modules
contains

     ampermod &first-dir

   then a checkout will create an `ampermod' directory which contains a
directory called `first-dir', which in turns contains all the
directories and files which live there.  For example, the command

     $ cvs co ampermod

will create the following files:

     ampermod/first-dir/file1
     ampermod/first-dir/file2
     ampermod/first-dir/sdir/sfile

   There is one quirk/bug: the messages that CVS prints omit the
`ampermod', and thus do not correctly display the location to which it
is checking out the files:

     $ cvs co ampermod
     cvs checkout: Updating first-dir
     U first-dir/file1
     U first-dir/file2
     cvs checkout: Updating first-dir/sdir
     U first-dir/sdir/sfile
     $

   Do not rely on this buggy behavior; it may get fixed in a future
release of CVS.
