This is a PWB script which I wrote to automatically create Related Articles subpages for those articles which don't have them, based on Special:WhatLinksHere.

These automatically created pages need checking and editing by a human, and articles for which this has not been done are listed in the Category:Bot-created Related Articles subpages.

This bot automatically creates "Related Articles" subpages for those articles which don't have
them, based on Special:WhatLinksHere.

The following parameters are supported:

-start            Start checking articles alphabetically from this point,
                  instead of starting from the beginning.

-always           Don't ask each time before creating a Related Articles
                  subpage; just create it anyway.

-debug            Don't actually create any Relate Articles subpages; just
                  show what would have been created.
