Mail to to discuss +;; features and additions. All suggestions are more than welcome. + +;; To use it, just switch to the buffer you want HTML-ized and type +;; `M-x htmlize-buffer'. You will be switched to a new buffer that +;; contains the resulting HTML code. You can edit and inspect this +;; buffer, or you can just save it with C-x C-w. `M-x htmlize-file' +;; will find a file, fontify it, and save the HTML version in +;; FILE.html, without any additional intervention. `M-x +;; htmlize-many-files' allows you to htmlize any number of files in +;; the same manner. `M-x htmlize-many-files-dired' does the same for +;; files marked in a dired buffer. + +;; htmlize supports three types of HTML output, selected by setting +;; `htmlize-output-type': `css', `inline-css', and `font'. In `css' +;; mode, htmlize uses cascading style sheets to specify colors; it +;; generates classes that correspond to Emacs faces and uses ... to color parts of text. In this mode, the +;; produced HTML is valid under the 4.01 strict DTD, as confirmed by +;; the W3C validator. `inline-css' is like `css', except the CSS is +;; put directly in the STYLE attribute of the SPAN element, making it +;; possible to paste the generated HTML to other documents. In `font' +;; mode, htmlize uses ... to colorize HTML, +;; which is not standard-compliant, but works better in older +;; browsers. `css' mode is the default. + +;; You can also use htmlize from your Emacs Lisp code. When called +;; non-interactively, `htmlize-buffer' and `htmlize-region' will +;; return the resulting HTML buffer, but will not change current +;; buffer or move the point. + +;; htmlize aims for compatibility with Emacsen 21 and later. Please +;; let me know if it doesn't work on the version of XEmacs or GNU +;; Emacs that you are using. The package relies on the presence of CL +;; extensions, especially for cross-emacs compatibility; please don't +;; try to remove that dependency.

+your documents to render correctly.  Also, the W3C validator requires
+submitted HTML documents to declare a charset.  So if you care about
+validation, you can use this to prevent the validator from bitching.
+
+Needless to say, if you set this, you should actually make sure that

+that is done by ensuring the correct \"file coding system\" for the

+considered Latin 1 and rewritten as \"&#CODE;\".  Characters with codes
+above 255 will be converted to \"&#UCS;\", where UCS denotes the Unicode
+code point of the character.  If the code point cannot be determined,
+the character will be copied unchanged, as would be the case if the
+option were nil.
+
+When the option is nil, the non-ASCII characters are copied to HTML
+without modification.  In that case, the web server and/or the browser
+must be set to understand the encoding that was used when saving the
+buffer.  (You might also want to specify it by setting
+`htmlize-html-charset'.)
+
+Note that in an HTML entity \"&#CODE;\", CODE is always a UCS code point,
+which has nothing to do with the charset the page is in.  For example,
+\"©\" *always* refers to the copyright symbol, regardless of charset
+specified by the META tag or the charset sent by the HTTP server.  In
+other words, \"©\" is exactly equivalent to \"©\".
+
+By default, entity conversion is turned on for Mule-enabled Emacsen and
+turned off otherwise.  This is because Mule knows the charset of
+non-ASCII characters in the buffer.  A non-Mule Emacs cannot tell
+whether a character with code 0xA9 represents Latin 1 copyright symbol,
+Latin 2 \"S with caron\", or something else altogether.  Setting this to
+t without Mule means asserting that 128-255 characters always mean Latin
