5 Version Matching
6
7 This module takes a matching string and a type and locates the version
8 record that satisfies the constraint described by the matching string.
9
10 Version: 1.2*
11 Release: o=Debian,v=2.1*,c=main
12 Release: v=2.1*
13 Release: a=testing
14 Release: n=squeeze
15 Release: *
16 Origin: deb.debian.org
17
18 Release may be a complex type that can specify matches for any of:
19 Version (v= with prefix)
20 Origin (o=)
21 Archive (a=) eg, unstable, testing, stable
22 Codename (n=) e.g. etch, lenny, squeeze, sid
23 Label (l=)
24 Component (c=)
25 Binary Architecture (b=)
26 If there are no equals signs in the string then it is scanned in short
27 form - if it starts with a number it is Version otherwise it is an
28 Archive or a Codename.
29
30 Release may be a '*' to match all releases.
