00006    Version Matching
00007 
00008    This module takes a matching string and a type and locates the version
00009    record that satisfies the constraint described by the matching string.
00010 
00011      Version: 1.2*
00012      Release: o=Debian,v=2.1*,c=main
00013      Release: v=2.1*
00014      Release: a=testing
00015      Release: n=squeeze
00016      Release: *
00017      Origin: ftp.debian.org
00018 
00019    Release may be a complex type that can specify matches for any of:
00020       Version (v= with prefix)
00021       Origin (o=)
00022       Archive (a=) eg, unstable, testing, stable
00023       Codename (n=) e.g. etch, lenny, squeeze, sid
00024       Label (l=)
00025       Component (c=)
00026       Binary Architecture (b=)
00027    If there are no equals signs in the string then it is scanned in short
00028    form - if it starts with a number it is Version otherwise it is an
00029    Archive or a Codename.
00030 
00031    Release may be a '*' to match all releases.
