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