DESCRIPTION
       All  of  these  programs are filters to do all sorts of strange things to text.  No personal, racial,
       religious or societal slurs are intended. For amusement only.

       All the filters read input from stdin, change it, and write the filtered text to stdout. Some filters
       also support reading from files and writing to stdout.

       b1ff   The B1FF filter

       lolcat As seen in internet gifs everywhere.

       cockney
              Cockney English

       chef   convert English on stdin to Mock Swedish on stdout

       eleet  K3wl hacker slang

       fanboy Speak  like  a  fanboy.  Filters  out  extraneous  words and focuses on the words fans use. By default, it will speak like a fan of git/Linus/linux development.  To  change  this,  pass  as parameters  the  words that the fanboy typically uses. Alternatively, pass the name of a topic that typically has fanboys to use a predefined word list.

       fudd   Elmer Fudd

       jethro Hillbilly text filter

       jive   Jive English

       jibberish
              Runs text through a random selection of the rest of the filters, to make really weird output.

       ken    English into Cockney, featuring (dubious) rhyming slang for a lot of computer terminology.

       kraut  Generates text with a bad German accent.

       kenny  Generates text as spoken by Kenny on South Park.

       ky00te This program places a very cute (and familiar to FurryMuck fans) accent on any text file.

       newspeak
              A-la-1984

       censor CDA-ize text

       pirate Talk like a pirate.

       rasterman

      scottish
              Fake scottish (dwarven) accent filter, inspired by the character "Durkon" from  Order  of  the
              Stick.

       spammer
              Turns honest text into something that is liable to be flagged as spam.

       scramble
              Scramble  the  "inner"  letters  of each word in the input into a random order.  The resulting
              text is still strangely readable.

       studly Studly caps.

       uniencode
              Use glorious unicode to the fullest possible extent. As seen previously in many man pages.

       upside-down
