AptPkg::Version(3)

NAME
AptPkg::Version - APT package versioning class

SYNOPSIS
use AptPkg::Version;

DESCRIPTION
The AptPkg::Version module provides an interface to APT's package version handling.

  AptPkg::Version
The AptPkg::Version package implements the APT pkgVersioningSystem class.

An instance of the AptPkg::Version class may be fetched using the "versioning" method from an AptPkg::System object.

The following methods are implemented:

label
    Return the description of the versioning system, for example:

        Standard .deb

    for Debian systems.

compare(A, B)
    Compare package version A with B, returning a negative value if A is an earlier version than B, zero if the same or a positive value if A is later.

rel_compare(A, B)
    Compare distribution release numbers.

check_dep(PKG, OP, DEP)
    Check that the package version PKG satisfies the relation OP to the dependency version DEP.

    The relation OP is specified in the Debian syntax regardless of the versioning system:

        <<  strictly earlier
        <=  earlier or equal
        =   exactly equal
        >=  later or equal
        >>  strictly later

upstream(VER)
    Return the upstream component of the given version string.
