+Create CVS Repository.
+======================
+::

+  $ export CVSROOT=/srv/cvsroot
+  $ cvs init
+
+  $ groupadd cvs
+  $ useradd -m -g cvs -s /bin/sh -c "CVS Repository"  cvs

+CVS workflow.
+=============
+
+Check out sources::
+
+  $ cvs co -P $proj
+
+Status of changes::
+
+  $ cvs status
+
+Compare local changes::
+
+  $ cvs diff -u $path
+
+Creating patch::
+
+  $ cvs diff -N -u -r >$patch
+
+History of changes::
+
+  $ cvs log $file
+
+Remove a file::
+
+  $ rm $file            # must first remove it locally
+  $ cvs rm $file        # schedules it for removal
+
+Add a file::
+
+  $ cvs add $file
+
+Check in local changes::
+
+  $ cvs ci
+
+Update local sources::
+
+  $ cvs update
+
+Move a file can not be done cleanly at the local level. The best way to do this
+with CVS is to go to the cvsroot repository and move the file or directory
+within the repository there. The cvsroot repository keeps all files in their RCS
+form of filename,v . The next cvs update will manifest the file move.
+
+Tagging sources::
+
+  $ cvs tag $name
+  $ cvs rtag $name
+
+Revert file::
+
+  $ rm $file            # remove it from local sources
+  $ cvs update $file    # get a new copy from the repository
+
