Telling CVS where your repository is
====================================

   There are several ways to tell CVS where to find the repository.
You can name the repository on the command line explicitly, with the
`-d' (for "directory") option:

     cvs -d /usr/local/cvsroot checkout yoyodyne/tc

   Or you can set the `$CVSROOT' environment variable to an absolute
path to the root of the repository, `/usr/local/cvsroot' in this
example.  To set `$CVSROOT', `csh' and `tcsh' users should have this
line in their `.cshrc' or `.tcshrc' files:

     setenv CVSROOT /usr/local/cvsroot

`sh' and `bash' users should instead have these lines in their
`.profile' or `.bashrc':

     CVSROOT=/usr/local/cvsroot
     export CVSROOT

   A repository specified with `-d' will override the `$CVSROOT'
environment variable.  Once you've checked a working copy out from the
repository, it will remember where its repository is (the information
is recorded in the `CVS/Root' file in the working copy).

   The `-d' option and the `CVS/Root' file both override the `$CVSROOT'
environment variable.  If `-d' option differs from `CVS/Root', the
former is used.  Of course, for proper operation they should be two
ways of referring to the same repository.
