The icons in this directory are referenced by the default treeview configuration
article MediaWiki:Treeview. They need to be uploaded to the wiki if they are
to be displayed as icons in the treeview.

One way is to upload images manually one-at-a-time using Special:Upload. A
batch upload script can avoid this tedium - later versions of MediaWiki come
with maintenance/importImages.php and there's also available elsewhere a
Python-based bot framework that supports uploading images[1] that might be of
use. If you have a Perl interpreter installed you might also be able to use the
"upload.pl" script in this directory, but see the CAVEAT top of script.

Some of the icons are fairly rough - contributions of more professional images
would be welcome - PNGs are preferred but GIFs are OK as long as they're
produced using software that legally licences the GIF patent.
