An RCSTag.T represents a symbolic tag in an RCS file. Each tag consists of a name and an associated revision number.

PROCEDURE Compare(READONLY t1, t2: T): [-1..1];
Compares two tags alphabetically by name.

PROCEDURE Equal(READONLY t1, t2: T): BOOLEAN;
Tests whether two tags have the same name.

PROCEDURE IsCVSBranch(READONLY t: T): BOOLEAN;
<=> The revision number of this tag is a CVS branch number (like 1.1.1, 2.1.4) or a magic CVS branch number (like 2.1.0.4, 4.3.3.2.0.8).
END RCSTag.
