       AptPkg::Version - APT package versioning class

       use AptPkg::Version;

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

       The AptPkg::Version package implements the APT pkgVersioningSystem

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

       The following methods are implemented:

	   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

	   Return the upstream component of the given version string.

       AptPkg::Config(3pm), AptPkg::System(3pm), AptPkg(3pm).
