2.4: The administrative files

The directory `$CVSROOT/CVSROOT' contains some administrative files. See Administrative files, for a complete description. You can use CVS without any of these files, but some commands work better when at least the `modules' file is properly set up.

The most important of these files is the `modules' file. It defines all modules in the repository. This is a sample `modules' file.

modules         CVSROOT modules
cvs             gnu/cvs
rcs             gnu/rcs
diff            gnu/diff
tc              yoyodyne/tc

The `modules' file is line oriented. In its simplest form each line contains the name of the module, whitespace, and the directory where the module resides. The directory is a path relative to $CVSROOT. The last four lines in the example above are examples of such lines.

The line that defines the module called `modules' uses features that are not explained here. See modules, for a full explanation of all the available features.

2.4.1: Editing administrative files

You edit the administrative files in the same way that you would edit any other module. Use `cvs checkout CVSROOT' to get a working copy, edit it, and commit your changes in the normal way.

It is possible to commit an erroneous administrative file. You can often fix the error and check in a new revision, but sometimes a particularly bad error in the administrative file makes it impossible to commit new revisions.
