filters were written to munge written language in amusing ways.  The earliest
and best known were legends such as the Swedish Chef filter and B1FF.

This package contains the following filter commands:
@enumerate
@item b1ff: a satire of a stereotypical Usenet newbie
@item censor: comply with the @acronym{CDA, Communications Decency Act}
@item chef: convert English to Mock Swedish
@item cockney: Cockney English
@item elee: k3wl hacker slang
@item fanboy: a stereotypical fan (supports custom fandoms)
@item fudd: Elmer Fudd
@item jethro: hillbilly text filter
@item jibberish: a random selection of these filters
@item jive: Jive English
@item ken: turn English into Cockney
@item kraut: a bad German accent
@item ky00te: a very cute accent
@item LOLCAT: as seen in Internet GIFs everywhere
@item nethackify: wiped-out text as found in nethack
@item newspeak: à la 1984
@item nyc: Brooklyn English
@item pirate: talk like a pirate
@item rasterman: straight from the keyboard of Carsten Haitzler
@item scottish: fake Scottish (Dwarven) accent
@item scramble: scramble the \"inner\" letters of each word
@item spammer: turn honest text into something liable to be flagged as spam
@item studly: studly caps.
@item uniencode: use glorious Unicode to the fullest possible extent
@item upside-down: flip the text upside down
@end enumerate

It also includes a growing library of built-in effects which showcase the
engine's features, including complex character movement via Paths, Waypoints,
and motion easing, with support for quadratic/cubic bezier curves, complex
animations via Scenes with symbol/color changes, layers, easing, and Path
synced progression, and variable stop/step color gradient generation.  Runs
