Append the access list of

Set the default branch to
.Ar rev .
.It Fl c Ns Ar string
Set comment leader to
.Ar string .
.It Fl e Ns Op Ar users

.It Fl I
Interactive mode.
.It Fl i

Specify the keyword substitution mode.

Enable strict locking on the RCS files.
See
.Xr rcsfile 5
for more details on locking.

Disable mail warnings when breaking a user's lock.
Normally,

will send a mail to the lock owner when his lock is removed by a call
to

Replace revision
.Ar rev Ns 's
log message with
.Ar msg .

Delete one or more revisions.
The specifications of the values or revisions are as follows:
.Bl -tag -width Ds
.It rev
Specific revision.
.It rev1:rev2
Delete all revisions of a branch between
.Ar rev1
and
.Ar rev2 .
.It rev1::rev2
Delete all revisions of a branch between
.Ar rev1
and
.Ar rev2
without deleting revisions
.Ar rev1
and
.Ar rev2 .
.It :rev
Delete all revisions of the branch until revision
.Ar rev .
.It rev:
Delete all revisions of the branch from revision
.Ar rev
until the last revision of the branch.
.El
.It Fl q
Be quiet about reporting.
.Sm off
.It Fl s Ar state Op : Ar rev
.Sm on
Sets the state of revision

.Ar file
specified as argument or from the string

given as argument if it is preceded by the

character.
If no argument is used, the descriptive text is taken from standard input
terminated by end-of-file or by a line containing the
.Sq \&.
character by itself.
.It Fl U
Disable strict locking on the RCS files.
See
.Xr rcsfile 5
for more details on locking.
