Multiple repositories
=====================

   In some situations it is a good idea to have more than one
repository, for instance if you have two development groups that work
on separate projects without sharing any code.  All you have to do to
have several repositories is to specify the appropriate repository,
using the `CVSROOT' environment variable, the `-d' option to CVS, or
(once you have checked out a working directory) by simply allowing CVS
to use the repository that was used to check out the working directory
(Note: Specifying a repository).

   The big advantage of having multiple repositories is that they can
reside on different servers.  With CVS version 1.10, a single command
cannot recurse into directories from different repositories.  With
development versions of CVS, you can check out code from multiple
servers into your working directory.  CVS will recurse and handle all
the details of making connections to as many server machines as
necessary to perform the requested command.  Here is an example of how
to set up a working directory:

     cvs -d server1:/cvs co dir1
     cd dir1
     cvs -d server2:/root co sdir
     cvs update

   The `cvs co' commands set up the working directory, and then the
`cvs update' command will contact server2, to update the dir1/sdir
subdirectory, and server1, to update everything else.
