use AptPkg::Version;

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)

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

<= earlier or equal
= exactly equal
>= later or equal
>> strictly later
upstream(VER): Return the upstream component of the given version string.
