NAME
         list-rewrites - reads penn treebanks, prints out all rewrites found

SYNOPSIS
         list-rewrites [options] [file ...]

         Options:
            -help        brief help message
            -man         full documentation
           --verbose     more verbose to STDERR
           --directinput allow TTY to STDIN

           --format FORMAT provide a different output format

           --terminal    include (exclude) terminal expansions
           --noterminal  default is --terminal

   Sample output
         $ echo "(S (NP (DET the) (NN dog)) (VP ran))" | ./list-rewrites
         S => NP VP
         NP => DET NN
         DET => the
         NN => dog
         VP => ran

OPTIONS
       --help
       -?  Show this help message.

       --man
           Show the manual page for this script.

       --directinput
           By default, if there is a human-operated TTY on STDIN, this script
           issues a usage message and exits (this is so users can run
           "list-rewrites" and get the usage message).  If you really want to
           type trees by hand on STDIN, add the --directinput flag.

       --verbose
           Repeatable option. Report more of what we're doing.

       --format FORMAT
           provide an alternative output format. The default is "%s =" %s\n>,
           which creates output like the example in "Sample output".

DESCRIPTION
       This program lists all rewrites in all trees presented by file or on
       STDIN to this script.

   CAVEATS
       The trees must be in Penn treebank format.

       The rewrites will not necessarily be unique; if you want them to be
       unique, you will have to pipe the output of this program into (e.g.)
       "sort | uniq".  This is deliberate, so that you can get counts from the
       output of this program as well as a survey of the rewrites in a corpus.

   TO DO
       None that I know of.
