The state is
an arbitrary string of characters used to describe a file (or a specific
revision of a file). States can be set or changed using the -s option, for CVS tools which support it. The state
of a file/revision can be modified without having to commit a new file/revision. The default state is ‘ Exp ’ (Experimental).
