+## Step 3: format conversion
+
+The next step is to convert Mediawiki conventions into Ikiwiki ones.
+
+### categories
+
+Mediawiki uses a special page name prefix to define "Categories", which
+otherwise behave like ikiwiki tags. You can convert every Mediawiki category
+into an ikiwiki tag name using a script such as
+
+ import sys, re
+ pattern = r'\[\[Category:([^\]]+)\]\]'
+
+ def manglecat(mo):
+ return '\[[!tag %s]]' % mo.group(1).strip().replace(' ','_')
+
+ for line in sys.stdin.readlines():
+ res = re.match(pattern, line)
+ if res:
+ sys.stdout.write(re.sub(pattern, manglecat, line))
+ else: sys.stdout.write(line)
+
+## Step 4: Mediawiki plugin or Converting to Markdown
+
+You can use a plugin to make ikiwiki support Mediawiki syntax, or you can
+convert pages to a format ikiwiki understands.
+
+### Step 4a: Mediawiki plugin
+
+The [[plugins/contrib/mediawiki]] plugin can be used by ikiwiki to interpret
+most of the Mediawiki syntax.
+
+The following things are not working:
+
+* templates
+* tables
+* spaces and other funky characters ("?") in page names
+
+### Step 4b: Converting pages
+
+#### Converting to Markdown
+
+There is a Python script for converting from the Mediawiki format to Markdown in [[mithro]]'s conversion repository at <http://github.com/mithro/media2iki>. *WARNING:* While the script tries to preserve everything is can, Markdown syntax is not as flexible as Mediawiki so the conversion is lossy!
+
+ # The script needs the mwlib library to work
+ # If you don't have easy_install installed, apt-get install python-setuptools
+ sudo easy_install mwlib
+
+ # Get the repository
+ git clone git://github.com/mithro/media2iki.git
+ cd media2iki
+
+ # Do a conversion
+ python mediawiki2markdown.py --no-strict --no-debugger <my mediawiki file> > output.md

+
+## Scripts
+
+### media2iki
+
+There is a repository of tools for converting MediaWiki to Git based Markdown wiki formats (such as ikiwiki and github wikis) at <http://github.com/mithro/media2iki>. It also includes a standalone tool for converting from the Mediawiki format to Markdown. [[mithro]] doesn't frequent this page, so please report issues on the [github issue tracker](https://github.com/mithro/media2iki/issues).
+
+### mediawiki2gitikiwiki (ruby)
+
+[[Albert]] wrote a ruby script to convert from mediawiki's database to ikiwiki at <https://github.com/docunext/mediawiki2gitikiwiki>
+
+### levitation (xml to git)
+
+[[scy]] wrote a python script to convert from mediawiki XML dumps to git repositories at <https://github.com/scy/levitation>.
+
+### git-mediawiki
+
+There's now support for mediawiki as a git remote:
+
+<https://github.com/moy/Git-Mediawiki/wiki>
+
+### mediawikigitdump
+[[Anarcat]] wrote a python script to convert from a mediawiki website to ikiwiki at git://src.anarcat.ath.cx/mediawikigitdump.git/. The script doesn't need any special access or privileges and communicates with the documented API (so it's a bit slower, but allows you to mirror sites you are not managing, like parts of Wikipedia). The script can also incrementally import new changes from a running site, through RecentChanges inspection. It also supports mithro's new Mediawiki2markdown converter (which I have a copy here: git://src.anarcat.ath.cx/media2iki.git/).

+
+> > You mean a debian package? :) media2iki is actually a submodule, so you need to go through extra steps to install it. mwlib being the most annoying part... I have fixed my script so it looks for media2iki directly in the submodule and improved the install instructions in the README file, but I'm not sure I can do much more short of starting to package the whole thing... --[[anarcat]]
+
+>>> You may have forgotten to push that, I don't see those changes.

+
+> > can you show me exactly which commandline arguments you're using? also, I have made improvements over the converter too, also available here: git://src/anarcat.ath.cx/media2iki.git/ -- [[anarcat]]
