This extension provides an offline viewing mode for Wikipedia dumps, or any other wiki.

Be aware that you will need a Wikipedia dump and the corresponding index, see the project page if you need help:

For a recent English, compressed backup of all article text (6.3Gb
once you build an index):

http://download.wikimedia.org/enwiki/20101011/enwiki-20101011-pages-articles.xml.bz2

For a small testing database (or if you speak Tagalog), try this

http://wikipedia-offline-patch.googlecode.com/files/wiki-splits-tl.zip

or browse many other languages and wiki projects:

http://dumps.wikimedia.org/backup-index.html

The project page has binary distributions for macos, windows, and linux, which include a webserver and supporting libraries. http://code.google.com/p/wikipedia-offline-patch

There is an unusual dependency: the Xapian indexing library and its PHP bindings. Also, you will have to configure some type of revision_text caching by setting $wgRevisionCacheExpiry and $wgCacheType.
