For wikis and wikia, generally if you are trying to get some url mirror, then websucker.py is an excellent option. This script is in the python sources so, to get this tool,
yumdownloader --source python Install the rpm downloaded in current directory and then go to ~/rpmbuild/SOUURCES. You should find a Python-*.tar.xz file here, just extract with
tar xvf Python*.tar.xz and there you go, you should find the tool in Tools/webchecker/websucker.
