5. Strong, Weak or No Locking

CVS is a powerful system and is highly customizable. CVS supports:

• Strong locking with "reserved checkouts" via cvs admin -l or Shell Scripts . Also read the Reserved checkouts. Here is a patch ( http://www.cvshome.org/dev/patches/editf) from Eric Griswold for reserved checkouts.
• Weak locking via 'cvs watch' features. Also see "cvs edit" to give a warning( http://www.cvshome.org/dev/text2/res2) if someone else is already editing the file.
• No locking - the default permitting concurrent editing of files.
