I suppose it would theoretically be possible to create a PHPTal-based skin which
pulls its XML template (the .pt file) from a user sub-page rather than a fixed file.

Restored the summary. Timwi completely changed the meaning of the request -- this is about site administrators customizing their wikis' display, not
end-users.

Huh? But site administrators can already customise their wiki (either by
modifying xhtml-slim.pt, or by writing an entirely new skin).

Right now adding a new skin requires hacking up a bunch of code in Language.php, Skin.php, User.php etc. That's a
royal pain in the neck -- and you have to carefully preserve your changes on even minor version upgrades.

It should be as easy as dropping in an extension: copy in a new directory and add an include() to your
LocalSettings.php. Particularly for skins that simply use new styles and/or a new PHPTal template, this should be a
relatively painless affair for a site administrator.

However, it's not that easy yet. That's why we have an enhancement request. :)

Really want this for 1.4 release, skin customization is a very frequently asked-about issue and right now
there's no easy answer.

Added a module "sampleskin" to the extensions package. It documents how to write
a skin extension. Also added the neccessary hooks to the main module.
