Simplified blog markup using "tagblog.awk"
------------------------------------------

tagblog.awk converts more-or-less straight text into valid HTML, and
supplies the document structure used in "Belisarius Blogs!".

What it converts:

"title=" is the title of the blog entry, rendered as an <h2>.  Can
  be multiple lines and include quotes, italics, links, etc.

"keywords=" are the Meta keywords.  Can be multiple lines; cannot
  include any other specials.  Keywords are written to a separate file
  for inclusion at the proper point in the final page.

"bq=" and "=bq" delimit block quotes (<blockquote>).

"link=" begins lines that contain links to other sites (<a href=).
  URL takes up the rest of the line.  Text between that line and a
  line consisting of "=link" becomes the hyperlink.  If "=link"
  immediately follows the last character of the text of the hyperlink,
  the <a> ends there, allowing links to end before punctuation.
  Otherwise, there's always a space after the </a>, and a space never
  ends the hypertext.

  For example:

  link=http://home.earthlink.net/~count_belisarius/starwars1.htm
  In Your Face, North Korea
  =link is the HTML version of ...

  Or:

  link=http://home.earthlink.net/~count_belisarius/starwars1.htm
  what I said recently=link:

Blank lines indicate the end/beginning of paragraphs, including
  paragraphs in block-quotes. 

Double quotes are converted to typographic quotes (&ldquo; and
  &rdquo;).  Apostrophes are converted to right single quotes (&rsquo;).

"---" is converted to an em-dash (&mdash;).

"..." is converted to a horizonal ellipsis (&hellip;).

"_" toggles italic face, except in block-quoted text.  "__" does the
  same for bold face.

"+" toggles citations ("<cite>")

"pre=" and "=pre" delimit preformatted text, which is rendered as is.
  These two tags, like "bq=" and "=bq", must be on separate lines.

All other text, including HTML tags, is passed through.  All text that
  is not inside a "pre=/=pre" is filled to a 70-character margin.

The script adds the current date at the bottom of the entry (if it's
handed a file beginning with the date), and performs other
housekeeping and formatting chores as required by the blog structure.
