Textile Takeover (Segfault No More!)

The Textile filter allows you to enter content using Textile, a simple, plain text syntax that is filtered into valid (X)HTML. It was originally developed by Dean Allen of textism.com, and several different versions (in several different programming languages) have been created. It is notably used by 37signals' Basecamp product, among many others.

Brad Choate developed an advanced implementation of Textile in Perl, Textile.pm, which includes extra features beyond those of Dean Allen’s Textile 2 implementation. This module was originally designed by Jim Riggs using TextilePHP, Jim's PHP port of Brad’s Textile.pm Perl module and Movable Type plugin.
