   Version Matching 
   
   This module takes a matching string and a type and locates the version
   record that satisfies the constraint described by the matching string.

     Version: 1.2*
     Release: o=Debian,v=2.1*,c=main
     Release: v=2.1*
     Release: *
     Origin: ftp.debian.org
   
   Release may be a complex type that can specify matches for any of:
      Version (v= with prefix)
      Origin (o=)
      Archive (a=)
      Label (l=)
      Component (c=)
   If there are no equals signs in the string then it is scanned in short
   form - if it starts with a number it is Version otherwise it is an 
   Archive.
   
   Release may be a '*' to match all releases.
