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.
