In the main PyGTK page:

http://www.pygtk.org/index.html

in the right-hand sidebar under the headings:

Documentation
Wiki

There is a link to a wiki page that does not exist:

https://wiki.gnome.org/PyGTK

"This page does not exist yet. You can create a new empty page, or use one of
the page templates."


However, on the same wiki this page exists and is the presumbable original
target of the link from the sidebar, but was perhaps moved in a
reorganization:

https://wiki.gnome.org/Projects/PyGTK
