       Be warned that the author has only a shallow understanding of the dpkg packaging  system,  so  there  are
       probably tons of bugs in this program.

       This  program  comes  with no warranties.  If running this program causes fire and brimstone to rain down
       upon the earth, you will be on our own.

       This program accesses the dpkg database directly in places, querying for data that cannot be  gotten  via
       dpkg.

dpkg-ruby Parses a dpkg status file(or other similarly formatted file) and outputs the resulting records.
       It can use regex on the field values to limit the returned records, and it can also be told which  fields
       to output.  As another option, it can sort the matched fields.

-ffilename--filefilename
              The file to parse.  The default is /var/lib/dpkg/status.

       -d[#]--debug[#]
              Each time this is specified, it increased the debug level.

       -sfield(s)--sortfield(s)
              A space or comma separated list of fields to sort on.

       -nfield(s)--numericfield(s)
              A space or comma separated list of fields that should be interpreted as numeric in value.

       -rs??--rec_sep??
              Output this string at the end of each output paragraph.

       -h--help Display some help.

       fieldname
              The  fields  from  the  file,  that  are  matched  with  the regex given.  The fieldnames are case
              insensitive.

       out_fieldname
              The fields from the file, that are outputted for each record.  If the first field listed is begins
              with ^, then the list that follows are fields NOT to be outputted.
