CVS - adminstration and usage

To start a repository, a suitable directory on the server machine must be initiated. To initiate, run:
#cvs -d /var/cvs init
This will create a directory CVSROOT under /var/cvs.

By default, CVS adds new files to the repository under the default group of the user performing the addition. But in multi-group repositories, this leads to CVS additions that are not readable by other developers. Fortunately CVS makes it easy to automate associating the new file with the proper group for the project. Edit the file /var/cvs/CVSROOT/loginfo:

Add the following lines to the bottom of the file:
module  (chgrp -Rf groupname $CVSROOT/module)
module  (chmod -Rf u+rw,g+rw,o= $CVSROOT/module)
Save the file and exit.
This will make sure any additions to the CVS repository will be automatically associated with the project's default group and permissions of user & group read/write, other with no perms.

Often what I do is add the following in one line:
modulename (somecmds;chgrp -Rf groupname $CVSROOT/modulename;chmod -Rf u+rw,g+rw,o-rwx $CVSROOT/modulename;)
This runs somecmds and then changes the group and read permissions for the whole tree.
