 Help from: --help-clumping:
 CLUMPING:
    "Clumping" defines a way of taking a stream of input records and rearranging
    them into to groups for consideration. The most common "consideration" for
    such a group of records is the application of one or more aggregators by recs-
    collate and the most common clumpers are those specifiable by recs-collate's
    normal options. However, other recs scripts can use "clumpers" and much more
    complex clumping is possible. A list of clumpers can be found via the --list-
    clumpers option on recs-collate and documentation for individual clumpers can

       --help-more            Larger help documentation
 
 Examples:
    Separate out a stream of text by PID into separate invocations of recs-frommultire.
       recs-fromre '^(.*PID=([0-9]*).*)$' -f line,pid | recs-multiplex -L line -k pid -- recs-frommultire ...
   Tag lines with counts by thread
       recs-multiplex -k thread -- recs-eval '{{nbr}} = ++$nbr'
 
 Cubing:
    Instead of added one entry for each input record, we add 2 ** (number of key
    fields), with every possible combination of fields replaced with the default
    of "ALL". This is not meant to be used with --adjacent or --size. If our key
    fields were x and y then we'd get output for {x = 1, y = 2}, {x = 1, y =
    ALL}, {x = ALL, y = 2} and {x = ALL, y = ALL}.
 
 Domain Lanuage Integration:
    The normal mechanism for specifying keys and aggregators allows one to
