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 cvsnt, or (once you have checked out a working directory) by simply allowing cvsnt to use the repository that was used to check out the working directory (the section called “Telling CVS where your repository is”).
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 cvsnt, you can check out code from multiple servers into your working directory. cvsnt 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.
