-/*
-   Ripped from the debian text filters package. This filter was originally
-   written by Joey Hess. While this wasn't mentioned clearly I would assume
-   that these two lines were released under the GNU GPL (so now is this
-   file, see the GPL.txt file).
-   (this is mostly reverse-engineered, the perl stuff made no sense to me
-   at all)
-   This implementation uses "J" to replace "r", to make it distinguishable
-   from the transited "f".
-   Good fonts to use with this plugin are sans-serif ones like Arial
-   or Verdana.
