It contains severely outdated information and does us more harm then good.

If you really really want it, then you'll need to look into some archives, but we 
cannot and will not advocate using several years old documentations.

Let me disagree with you. I think it deserves to be placed at least at http://museum.php.net/

Seems like Richard took the trouble and re-implemented the extended CHM into PhD.

We are having some trouble with copying it over to the rsync box so it can be 
synced to the mirrors though.. Looking into it at

The new enhanced chm format includes the user notes, like the old "extended" chm 
file. It does not include ability for the 
end user to create alternative "skins" for the CHM file.

It was also a lot easier to simply incorporate the user notes into the main body 
of the HTML than to have 2 separate CHM 
files (manual and notes) and then to use JavaScript to merge the content like 
the old extended CHM files.

As it stands, there is nothing else to be done new enhanced format with regard 
to the user notes.

When the new PHP website re-styling is complete, the finalised styling will be 
incorporated into the CHM files. This is 
all ready to go. If you are in a position to build your own CHM files, then you 
take a look at 
http://svn.php.net/viewvc/phpdoc/doc-base/trunk/scripts/build-chms.php?
revision=310810&view=markup#l187 to see how to 
include the current styling into the CHM files.

I'd still place it into museum for PHP4. CSS styling was awesome. IIRC comments 
were split, because of CHM size limitations.

I don't think it was CHM size limitations, but the download size issues (though 
broadband is certainly more prevalent now). The underlying technology hasn't 
changed and the user notes only increases the CHM file size by 230%. As for 
including it in the museum, I'd be very worried about including it due to the very 
outdated information contained in it. Also, the mechanism used for styling removed 
any found search results. It wasn't ideal and I was unable to find a solution to 
preserve the found/highlighted search terms as well as allowing the custom 
styling. So, flawed and outdated. Not an ideal candidate for the museum.

Lol. What kind of information do you expect in museum? =)

I believe xCHM manual significantly contributed to making PHP4 popular on Windows. 
Yes, it got heavy and outdated with time, and it is no more actual nowadays. I 
spend a lot of time trying to resurrect it, and for me it would be nice to have it 
zipped online for the history.
