Usage: recs-totable <args> [<files>]
   Prints out an html table for the records from input or from <files>.

   --keys <keys>                Keys to print in the table. May be specified
                                multiple times, may be comma separated. Default
                                to all fields in the first record. May be a
                                keyspec or a keygroup, see '--help-keys' for
                                more information
   --noheader                   Do not print the header row
   --rowattributes              HTML attributes to put on the tr tags
   --cellattributes             HTML attributes to put on the td and th tag
   --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-keygroups  Help on keygroups, a way of specifying multiple keys
      --help-keys       Help on keygroups and keyspecs

Help from: --help-keygroups:
KEY GROUPS
   SYNTAX: !regex!opt1!opt2... Key groups are a way of specifying multiple
   fields to a recs command with a single argument or function. They are
   generally regexes, and have several options to control what fields they
   match. By default you give a regex, and it will be matched against all first
   level keys of a record to come up with the record list. For instance, in a
   record like this:

   { 'zip': 1, 'zap': 2, 'foo': { 'bar': 3 } }

   Key group: !z! would get the keys 'zip' and 'zap'

   You can have a literal '!' in your regex, just escape it with a \.

   Normally, key groups will only match keys whose values are scalars. This can
   be changed with the 'returnrefs' or rr flag.

   With the above record !f! would match no fields, but !f!rr would match foo
   (which has a value of a hash ref)

   Options on KeyGroups:
      returnrefs, rr  - Return keys that have reference values (default:off)
      full, f         - Regex should match against full keys (recurse fully)
      depth=NUM,d=NUM - Only match keys at NUM depth (regex will match against
                        full keyspec)
      sort, s         - sort keyspecs lexically

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
