Help from: --help-basic:
Usage: recs-frommultire <args> [<files>]
   Match multiple regexes against each line of input (or lines of <files>). Various parameters control when the accumulated fields
   are flushed to output as a record and which, if any, fields are cleared when the record is flushed.

   By default regexes do not necessarily flush on either side, would-be field collisions cause a flush, EOF causes a flush if any
   fields are set, and all fields are cleared on a flush.

Arguments:
   --no-flush-regex|--regex|--re <regex>  Add a normal regex.
   --pre-flush-regex|--pre <regex>        Add a regex that flushes before interpretting fields when matched.
   --post-flush-regex|--post <regex>      Add a regex that flushes after interpretting fields when matched.
   --double-flush-regex|--double <regex>  Add a regex that flushes both before and after interprettying fields when matched.
   --clobber                              Do not flush records when a field from a match would clobber an already existing field
                                          and do not flush at EOF.
   --keep-all                             Do not clear any fields on a flush.
   --keep <fields>                        Do not clear this comma separated list of fields on a flush.
   --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

   <regex> - Syntax is: '<KEY1>,<KEY2>=REGEX'. KEY field names are optional. The key names may be key specs, see '--help-keyspecs'
   for more. Field names may not be keygroups. If field matches $NUM, then that match number in the regex will be used as the
   field name

Examples:
   Typical use case one: parse several fields on separate lines
      recs-frommultire --re 'fname,lname=^Name: (.*) (.*)$' --re 'addr=^Address: (.*)$'
   Typical use case two: some fields apply to multiple records ("department" here)
      recs-frommultire --post 'fname,lname=^Name: (.*) (.*)$' --re 'department=^Department: (.*)$' --clobber --keep team

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
