Help from: --help-basic:
Usage: recs-sort <args> [<files>]
   Sorts records from input or from <files>. You may sort on a list of keys,
   each key sorted lexically (alpha order) or numerically

   --key <keyspec>              May be comma separated, May be specified
                                multiple times. Each keyspec is a name or a
                                name=sortType. The name should be a field name
                                to sort on. The sort type should be either
                                lexical or numeric. Default sort type is
                                lexical (can also use nat, lex, n, and l).
                                Additionallly, the sort type may be prefixed
                                with '-' to indicate a decreasing sort order.
                                Additionally, the sort type may be postfixed
                                with '*' to sort the special value 'ALL' to the
                                end (useful for the output of recs-collate --
                                cube). See perldoc for
                                App::RecordStream::Record for more on sort
                                specs. May be a key spec, see '--help-keyspecs'
                                for more. Cannot be a keygroup.
   --reverse                    Reverses the sort order
   --filename-key|fk <keyspec>  Add a key with the source filename (if no
                                filename is applicable will put NONE)

  Help Options:
      --help-all       Output all help for this script
      --help           This help screen
      --help-keyspecs  Help on keyspecs, a way to index deeply and with regexes

Examples:
   Sort on the id field, a numeric
      recs-sort --key id=numeric
   Sort on age, then name
      recs-sort --key age=numeric,name
   Sort on decreasing size, name
      recs-sort --key size=-numeric --key name

Help from: --help-keyspecs:
  KEY SPECS
   A key spec is short way of specifying a field with prefixes or regular
   expressions, it may also be nested into hashes and arrays. Use a '/' to nest
   into a hash and a '#NUM' to index into an array (i.e. #2)

   An example is in order, take a record like this:

     {"biz":["a","b","c"],"foo":{"bar 1":1},"zap":"blah1"}
     {"biz":["a","b","c"],"foo":{"bar 1":2},"zap":"blah2"}
     {"biz":["a","b","c"],"foo":{"bar 1":3},"zap":"blah3"}

   In this case a key spec of 'foo/bar 1' would have the values 1,2, and 3 in
   the respective records.

   Similarly, 'biz/#0' would have the value of 'a' for all 3 records

   You can also prefix key specs with '@' to engage the fuzzy matching logic

   Fuzzy matching works like this in order, first key to match wins
     1. Exact match ( eq )
     2. Prefix match ( m/^/ )
     3. Match anywehre in the key (m//)

   So, in the above example '@b/#2', the 'b' portion would expand to 'biz' and 2
   would be the index into the array, so all records would have the value of 'c'

   Simiarly, @f/b would have values 1, 2, and 3

   You can escape / with a \. For example, if you have a record:
   {"foo/bar":2}

   You can address that key with foo\/bar
