+
+ 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.
