  22 ;;; Commentary:
  23
  24 ;; The module facilitates the keeping and publication of a journal.
  25 ;; When publishing to HTML, it assumes the form of a web log, or blog.
  26 ;;
  27 ;; The input format for each entry is as follows:
  28 ;;
  29 ;;   * 20040317: Title of entry
  30 ;;
  31 ;;   Text for the entry.
  32 ;;
  33 ;;   <qotd>
  34 ;;   "You know who you are. It comes down to a simple gut check: You
  35 ;;   either love what you do or you don't. Period." -- P. Bronson
  36 ;;   </qotd>
  37 ;;
  38 ;; The "qotd", or Quote of the Day, is entirely optional.  When
  39 ;; generated to HTML, this entry is rendered as:
  40 ;;
  41 ;;   <div id="entry">
  42 ;;     <div id="entry-qotd">
  43 ;;       <h3>Quote of the Day:</h3>
  44 ;;       <p>"You know who you are. It comes down to a simple gut
  45 ;;         check: You either love what you do or you don't. Period."
  46 ;;         -- P. Bronson</p>
  47 ;;     </div>
  48 ;;     <div id="entry-body">
  49 ;;       <div id="entry-head">
  50 ;;         <div id="entry-date">
  51 ;;           <span class="date">March 17, 2004</span>
  52 ;;         </div>
  53 ;;         <div id="entry-title">
  54 ;;           <h2>Title of entry</h2>
  55 ;;         </div>
  56 ;;       </div>
  57 ;;       <div id="entry-text">
  58 ;;         <p>Text for the entry.</p>
  59 ;;       </div>
  60 ;;     </div>
  61 ;;   </div>
  62 ;;
  63 ;; The plurality of "div" tags makes it possible to display the
  64 ;; entries in any form you wish, using a CSS style.
  65 ;;
  66 ;; Also, an .RDF file can be generated from your journal by publishing
  67 ;; it with the "rdf" style.  It uses the first two sentences of the
  68 ;; first paragraph of each entry as its "description", and
  69 ;; autogenerates tags for linking to the various entries.
