   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    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.
