VERSION

       $Revision: 1.23 $

DESCRIPTION

       This module is a Perl mail client interface for sending message that support HTML format and build them for you..  This module provide
       routine to transform a HTML page in MIME::Lite mail.  So you need this module to use MIME-Lite-HTML possibilities

   What's happen ?
       The job done is:

       o   Get the file (LWP) if needed

       o   Parse page to find include images (gif, jpg, flash)

       o   Attach them to mail with adequat header if asked (default)

       o   Include external CSS,Javascript file

       o   Replace relative url with absolute one

       o   Build the final MIME-Lite object with each part found

   Usage
       Did you alread see link like "Send this page to a friend" ?. With this module, you can do script that to this in 3 lines.

       It can be used too in a HTML newsletter. You make a classic HTML page, and give just url to MIME::Lite::HTML.

   Construction
       MIME-Lite-HTML use a MIME-Lite object, and RFC2557 construction:

       If images and text are present, construction use is:

	 --> multipart/alternative
	 ------> text/plain
	 ------> multipart/related
	 -------------> text/html
	 -------------> each images

       If no images but text is present, this is that:

	 ---> multipart/alternative
	 -------> text/plain if present
	 -------> text/html

       If images but no text, this is:

	 ---> multipart/related
	 -------> text/html
	 -------> each images

       If no images and no text, this is:

	 ---> text/html

   Documentation
       Additionnal documentation can be found here:

       o   MIME-lite module

       o   RFC 822, RFC 1521, RFC 1522 and specially RFC 2557 (MIME Encapsulation of Aggregate Documents, such as HTML)

   Clients tested
       HTML in mail is not full supported so this module can't work with all email clients. If some client recognize HTML, they didn't support
       images include in HTML. So in fact, they recognize multipart/relative but not multipart/related.

       Netscape Messager (Linux-Windows)
	   100% ok

       Outlook Express (Windows-Mac)
	   100% ok. Mac work only with Content-Location header. Thx to Steve Benbow for give mr this feedback and for his test.

       Eudora (Windows)
	   If this module just send HTML and text, (without images), 100% ok.

	   With images, Eudora didn't recognize multipart/related part as describe in RFC 2557 even if he can read his own HTML mail. So if images
	   are present in HTML part, text and HTML part will be displayed both, text part in first.  Two additional headers will be displayed in
	   HTML part too in this case.	Version 1.0 of this module correct major problem of headers displayed with image include in HTML part.

       KMail (Linux)
	   If this module just send HTML and text, (without images), 100% ok.

	   In other case, Kmail didn't support image include in HTML. So if you set in KMail "Prefer HTML to text", it display HTML with images
	   broken. Otherwise, it display text part.

       Pegasus (Windows)
	   If this module just send HTML and text, (without images), 100% ok.

	   Pegasus didn't support images in HTML. When it find a multipart/related message, it ignore it, and display text part.

       If you find others mail client who support (or not support) MIME-Lite-HTML module, give me some feedback ! If you want be sure that your
       mail can be read by maximum of people, (so not only OE and Netscape), don't include images in your mail, and use a text buffer too. If
       multipart/related mail is not recognize, multipart/alternative can be read by the most of mail client.

   Install on WinX with ActiveState / PPM
       Just do in DOS "shell":

	 c: ppm
	 > set repository alian http://www.alianwebserver.com/perl/CPAN
	 > install MIME-Lite-HTML
	 > quit

Public Interface
       new(%hash)
	   Create a new instance of MIME::Lite::HTML.

	   The hash can have this key : [Url], [Proxy], [Debug], [IncludeType],
	    [HashTemplate], [LoginDetails], [TextCharset], [HTMLCharset],
	    [TextEncoding], [HTMLEncoding], [remove_jscript]

	   Url ... is url to parse and send. If this param is found, call of parse routine and send of mail is done. Else you must use parse
	       routine of MIME::Lite::HTML and send of MIME::Lite.

	   Proxy
	       ... is url of proxy to use.

		 Eg: Proxy => 'http://192.168.100.166:8080'

	   remove_jscript
	       if set, remove all script code from html source

		 Eg: remove_jscript => 1

	   Debug
	       ... is trace to stdout during parsing.

		 Eg: Debug => 1

	   IncludeType
	       ... is method to use when finding images:

	       location
		   Default method is embed them in mail whith 'Content-Location' header.

	       cid You use a 'Content-CID' header.

	       extern
		   Images are not embed, relative url are just replace with absolute, so images are fetch when user read mail. (Server must be
		   reachable !)

	   $hash{'HashTemplate'}
	       ... is a reference to a hash. If present, MIME::Lite::HTML will substitute <? $name ?> with $hash{'HashTemplate'}{'name'} when
	       parse url to send. $hash{'HashTemplate'} can be used too for include data for subelement.  Eg:

		 $hash{'HashTemplate'}{'http://www.al.com/images/sommaire.gif'}=@data;

	       or

		 $hash{'HashTemplate'}{'http://www.al.com/script.js'}="alert("Hello world");;

	       When module find the image http://www.alianwebserver.com/images/sommaire.gif in buffer, it don't get image with LWP but use data
	       found in $hash{'HashTemplate'}. (See eg/example2.pl)

	   LoginDetails
	       ... is the couple user:password for use with restricted url.

		 Eg: LoginDetails => 'my_user:my_password'

	   TextCharset
	       ... is the character set to use for the text part.

		 Eg: TextCharset => 'iso-8859-7'

	       for Greek. If none specified, the default is used (iso-8859-1).

	   HTMLCharset
	       ... is the character set to use for the html part.

		 Eg:  HTMLCharset => 'iso-8859-7'

	       for Greek. If none specified, the default is used (iso-8859-1).	Take care, as that option does NOT change the character set of the
	       HTML page, it only changes the character set of the mime part.

	   TextEncoding
	       ... is the Encoding to be used for the text part (if such a part exists). If none specified, the default is used(7bit).

		 Eg: TextEncoding => 'base64'

	   HTMLEncoding
	       ... is the Encoding to be used for the html part. If none specified, the default is used (quoted-printable).

		 Eg: HTMLEncoding => 'base64'.

	   Others keys are use with MIME::Lite constructor.

	   This MIME-Lite keys are: Bcc, Encrypted, Received, Sender, Cc, From, References, Subject, Comments, Keywords, Reply-To To, Content-*,
	   Message-ID,Resent-*, X-*,Date, MIME-Version, Return-Path, Organization

       parse($html, [$url_txt], [$url_base])
	   Subroutine used for created HTML mail with MIME-Lite

	   Parameters:

	   $html
	       Url of HTML file to send, can be a local file. If $url is not an url (http or https or ftp or file or nntp), $url is used as a
	       buffer.	Example :

		 http://www.alianwebserver.com
		 file://c|/tmp/index.html
		 <img src=toto.gif>

	   $url_txt
	       Url of text part to send for person who doesn't support HTML mail.  As $html, $url_txt can be a simple buffer.

	   $url_base
	       $url_base is used if $html is a buffer, for get element found in HTML buffer.

	   Return the MIME::Lite part to send

       size()
	   Display size of mail in characters (so octets) that will be send.  (So use it *after* parse method). Use this method for control size
	   of mail send, I personnaly hate receive 500k by mail.  I pay for a 33k modem :-(

	   $txt
	       Buffer of text part

	   @mail
	       List of images attached to HTML part. Each item is a MIME-Lite object.

	   See "Construction" in "Description" for know how MIME-Lite object is build.

Error Handling
       The set_err routine is used privately. You can ask for an array of all the errors which occured inside the parse routine by calling:

       @errors = $mailHTML->errstr;

       If no errors where found, it'll return undef.

CGI Example
	 #!/usr/bin/perl -w
	 # A cgi program that do "Mail this page to a friend";
	 # Call this script like this :
	 # script.cgi?email=myfriend@isp.com&url=http://www.go.com
	 use strict;
	 use CGI qw/:standard/;
	 use CGI::Carp qw/fatalsToBrowser/;
	 use MIME::Lite::HTML;

	 my $mailHTML = new MIME::Lite::HTML
	    From     => 'MIME-Lite@alianwebserver.com',
	    To	     => param('email'),
	    Subject => 'Your url: '.param('url');

	 my $MIMEmail = $mailHTML->parse(param('url'));
	 $MIMEmail->send; # or for win user : $mail->send_by_smtp('smtp.fai.com');
	 print header,"Mail envoye (", param('url'), " to ", param('email'),")<br>
