;;; Commentary:
;; This file specifies a form for recording poetry. It is as follows.
;;
;; Title
;;
;;
;; Body of poem
;;
;;
;; Annotations, history, notes, etc.
;;
;; The `muse-poem' module makes it easy to attractively publish and
;; reference poems in this format, using the "memoir" module for LaTeX
;; publishing. It will also markup poems for every other output
;; style, though none are nearly as pretty.
;;
;; Once a poem is written in this format, just publish it to PDF using
;; the "poem-pdf" style. To make an inlined reference to a poem that
;; you've written -- for example, from a blog page -- there is a
;; "poem" tag defined by this module:
;;
;; <poem title="name.of.poem.page">
;;
;; Let's assume the template above was called "name.of.poem.page";
;; then the above tag would result in this inclusion:
;;
;; ** Title
;;
;; > Body of poem
;;
;; I use this module for publishing all of the poems on my website,
;; which are at: http://www.newartisans.com/johnw/poems.html.
