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.
