erin.el: Emacs editing mode for TWiki pages

erin.el is an Emacs editing mode for the Wiki markup of TWiki. The current version of erin.el mostly just does semi-WYSIWYG fontifying and heading renumbering.

To install, put file erin.el into one of the directories that's listed in your Emacs load-path, (optionally) byte-compile `erin.el', and add the following expression to your .emacs file:

(require 'erin)

Files named with the extension .twiki will be opened in erin-mode automatically. You can see a sampler of fontified TWiki markup with the key sequence: M-x erin-sampler RET

Headings can be renumbered with the erin-renumber-headings command (key sequence C-c C-r). The number of pluses in the TWiki markup denotes the level of the heading. Headings with TWiki !! markup after the pluses are unnumbered. For an example of unnumbered and numbered headings:

---+!! My Important Wiki Paper
---+ 1 Introduction
---+ 2 Theory
---++ 2.1 Pretty Pictures View of Theory
---++ 2.2 Cryptic Equations View of Theory
---+++ 2.2.1 Integral Symbol
---+ 3 Practice

Unless and until a future version of erin.el talks to a TWiki server directly, you need to interface them manually: select all the text in a TWiki page edit form, cut it, paste it into an Emacs buffer (in erin-mode), edit the text, cut it from Emacs, and paste it back into the TWiki form. It's still a win for nontrivial pages.

Just as TWiki is not named after Twiki, erin.el is not named after Twiki's arguably more attractive co-star, Erin Gray.
