   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: *
  15      Origin: ftp.debian.org
  16
  17    Release may be a complex type that can specify matches for any of:
  18       Version (v= with prefix)
  19       Origin (o=)
  20       Archive (a=)
  21       Label (l=)
  22       Component (c=)
  23    If there are no equals signs in the string then it is scanned in short
  24    form - if it starts with a number it is Version otherwise it is an
  25    Archive.
  26
  27    Release may be a '*' to match all releases.
