;;; Commentary:
;; 
;;    First up, let me say that this would not have been possible if
;;    it weren't for JWZ's jwz-lj.el.  In fact, large portions of
;;    lj.el were lifted directly from jwz-lj.el.  So, thank you very
;;    much, Jamie!
;;
;;; *** IMPORTANT BIT ***
;;
;;    You MUST compose your LJ posts in raw HTML (XHTML 1.0 Transitional
;;    if you plan on validating the markup before you submit the post).
;;    Don't bitch and complain about how hard or inconvenient that is.
;;    I'm not listening.  The buffer where you write your posts is in a
;;    derivative of html-mode so you've got everything you need right at
;;    your fingertips.  And anyway, writing your LJ posts in raw HTML
;;    gives you much more control over what the finished post will look
;;    like.
;;
;;    Another important step before you can use lj.el is to log into
;;    your LiveJournal a/c with your web browser and check the "remember
;;    me" box on the login page.  This is the only way to have your
;;    password stored in your cookies.  Don't worry, it is encrypted.
;;
;;; A Note about validating your markup:
;;
;;    Before you can validate your posts (with psgml) you need to
;;    ensure that...
;;
;;        o You have both, the psgml, and psgml-dtds XEmacs packages
;;          installed.  Well, duh!
;;
;;        o You have a working sgml toolchain.  It is way beyond the
;;          scope of this lib (or my patience) to show you how.
;;          Instead, do what the pros do and see:
;;
;;          http://www.linuxfromscratch.org/blfs/view/svn/pst/sgml.html
;;
;;        o psgml needs to know where your catalog files are.  The
;;          easiest way to do that is to set SGML_CATALOG_FILES in
;;          your shell environment...
;;
;;          export SGML_CATALOG_FILES=/etc/sgml/catalog:/path/to/psgml-dtds/CATALOG
;;
;;; Install/Set Up:
;;
;;    Whack this lib into your load-path somewhere and...
;;     (require 'lj)
;;     (setq lj-user-id "your_lj_id")
;;
;;    When you want to compose a new LJ entry... M-x lj RET
;;
;;    There's nothing hard or overly complicated here.  Take a look at
;;    describe-mode (`C-h m') which will show you the keybindings
;;    available.  All of the "lj-mode specific" interactive commands
;;    have a binding.  There are 3 "global" commands that don't...
;;
;;         #'lj
;;         #'lj-blog-buffer
;;         #'lj-blog-region
;;
;;    The only reason they don't have keybindings is that I think it'd
;;    be bad form on my part to set global keys for you.  Assign them
;;    to keys if you want.
;;
;;    All of the "headers" have completion too.  A couple of tips
;;    about the completion...
;;
;;      - By default iso-left-tab (that's shift-tab for the clueless)
;;        will cycle backwards.
;;
;;      - The trick to getting multiple tags is to type a comma (`,')
;;        plus the first letter or two of the next tag you wanna use
;;        after the last inserted tag.
;;
;;; Twitter: (broken, don't use)
;;
;;    This is currently broken because twitter turned off Basic Auth
;;
;;    You can optionally post the subject header of your blog entry as
;;    a status update to Twitter, along with a URL to the entry on
;;    livejournal.com.  To do so, you must set...
;;
;;        `lj-twitter-flag'
;;        `lj-twitter-username'
;;        `lj-twitter-password'
;;
;;    The down side to this is that your twitter username and password
;;    are stored in clear text.  I'll work on a way to make that safer
;;    later.
;;
;;    Have fun with it!

;;; Todo:
;;
;;    o Make "Writer's Block" a bit friendlier.  Add the ability to
;;      choose different qotd's after one has been selected.  Also, be
;;      able to view older qotd's.
;;
;;    o Rewrite the twitter code to use OAuth.
;;

;;; Bugs:
;;
;;    I've tried to make this compatible with XEmacs 21.5 and 21.4,
;;    but I don't have either of those installed so I'm not 100%
;;    certain.  As for GNU/Emacs... absolutely no idea, but I'd doubt
;;    that this is anywhere near compatible.

Argument BODY, a string, is the body of the post.
Argument USER, a string, is the LJ userid to post as.

Optional argument SECURITY, a string, is the security level this post
will have.  The default is `lj-default-security-level'.

Optional argument TAGS, a string, which is a comma delimited list of
tags to add to this post.

Optional argument COMMUNITY, a string, which is the name of a LJ forum
to send this post to instead of the user's blog.

Optional argument AUTO-FORMAT, when non-nil request that the LJ server
automatically formats the post.  The default is nil, which means the
post should NOT be auto formatted by LJ.

Optional argument NO-COMMENTS, when non-nil means to turn off comments
on the post.

Optional argument MOOD, a string or an integer, is the post's \"mood\"
header.  If it is an integer, it is a \"mood id\" which is mapped to a
string by LJ.

Optional argument LOCATION, a string, free-form text describing your
current location.  Livejournal turns it into a search URL to google
maps.

Optional argument MUSIC, a string, of the currently playing mp3/ogg.

Optional argument PICKW, a string, of the userpic keyword to use.  If
omitted, your default LJ userpic will be used.

Optional argument DATE, an internal time value as returned by
`encode-time'.  Used to set a date/time on a post, if omitted the
current time is used.

Optional boolean argument BACKDATED, causes the \"backdated\" flag to be
set which will prevent the post from showing up on friends pages."

  "Convert the plain text in the region BEG - END to html.

With optional argument, NOPBR, don't add <p>..</p> or <br /> tags.

This is an extremely basic converter.  All it really does is wrap
paragraphs in <p>...</p>, and add <br /> to the end of each non-blank
line.  It will also convert old 70's style text highlighting to the
HTML equivalent.  e.g. _text_ -> <u>text</u>, *text* -> <b>text</b>.
It also converts non-ASCII to HTML entities, and converts URL's and
email addresses to hyperlinks.  Email addresses are obfuscated in an
attempt to protect against spam harvesters.

Apart from the bold, underline, and hyperlink stuff, that's all the
eye-candy you'll get.  Forget fonts, colours, tables, and lists.
That's not what this is about.  The idea is to keep the text as close
to \"as-is\" without resorting to using <pre>...</pre> tags.

Calling this function on text that contains \"<lj*>\" will break those
tags.  So take note of what you are doing."
