/* ######################################################################
Version Matching
This module takes a matching string and a type and locates the version
record that satisfies the constraint described by the matching string.
Version: 1.2*
Release: o=Debian,v=2.1*,c=main
Release: v=2.1*
Release: a=testing
Release: n=squeeze
Release: *
Origin: ftp.debian.org
Release may be a complex type that can specify matches for any of:
Version (v= with prefix)
Origin (o=)
Archive (a=) eg, unstable, testing, stable
Codename (n=) e.g. etch, lenny, squeeze, sid
Label (l=)
Component (c=)
Binary Architecture (b=)
If there are no equals signs in the string then it is scanned in short
form - if it starts with a number it is Version otherwise it is an
Archive or a Codename.
Release may be a '*' to match all releases.
