NAME

VCS::LibCVS::Datum::TagSpec - A CVS datum for a tag specification

SYNOPSIS

Top

  $string = VCS::LibCVS::Datum::TagSpec->new("Trelease_1_01");

DESCRIPTION

Top

The concatentation of a tag type and value, like:

  Trelease_1_01
  D2002.11.18.05.00.00

These are the tag types for LibCVS:

  VCS::LibCVS::Datum::TagSpec::TYPE_BRANCH      (T)
  VCS::LibCVS::Datum::TagSpec::TYPE_DATE        (D)
  VCS::LibCVS::Datum::TagSpec::TYPE_NONBRANCH   (N)
  VCS::LibCVS::Datum::TagSpec::TYPE_REVISION    (R)

This usage deviates from that in CVS, which is: (This should be validated for accuracy.)

  D  A date tag
  T  In an entry line is any named symbolic or revision tag
     In a directory (CVS/Tag) indicates a branch tag
  N  In a directory (CVS/Tag) indicates a non-branch tag
