It looks like the "Programming languages and libraries" part of the page currently yearns for encyclopedic completeness (listing any framework ever written and then not maintained for decades) instead of usefulness. Might be something to even move to a separate page.

See T254953: Review & improve bot documentation on meta & mediawiki for the way bigger issue of sorting this out, listing

• https://www.mediawiki.org/wiki/Manual:Creating_a_bot
• https://www.mediawiki.org/wiki/Manual:Bots
• https://en.wikipedia.org/wiki/Help:Creating_a_bot (most useful, IMHO)
• https://en.wikipedia.org/wiki/Wikipedia:Bots
• https://meta.wikimedia.org/wiki/Bot

Interestingly,

• https://meta.wikimedia.org/wiki/Small_wiki_toolkits/Starter_kit/Bots_and_Tools#Bots links to https://en.wikipedia.org/wiki/Wikipedia:Bots and https://wikitech.wikimedia.org/wiki/Help:Toolforge/Developing_successful_tools .
• https://meta.wikimedia.org/wiki/Small_wiki_toolkits itself links for "Learn to use Pywikibot, a tool framework that helps to create bots." to https://www.mediawiki.org/wiki/Manual:Pywikibot though we have no tutorial (see T134495: Create a "my first Pywikibot bot" tutorial for Toolforge about that, or tasks with unclear scope and criteria like T288833: Improve documentation for pywikibot).

Never have seen this page before.

Alert: Much of the content of https://www.mediawiki.org/wiki/Manual:Creating_a_bot is duplicated on https://en.wikipedia.org/wiki/Help:Creating_a_bot.

I made 44 edits on https://www.mediawiki.org/w/index.php?title=Manual:Creating_a_bot&action=history to manually sync its content with https://en.wikipedia.org/w/index.php?title=Help:Creating_a_bot . (Simply diff doesn't work because of all that horrible Translate markup.)

I also made 2 edits on https://en.wikipedia.org/w/index.php?title=Help:Creating_a_bot to correct outdated/wrong stuff.

Also replaced the weird link to en.wp on https://meta.wikimedia.org/w/index.php?title=Small_wiki_toolkits%2FStarter_kit%2FBots_and_Tools&type=revision&diff=23931530&oldid=23458505 with a link to this very wiki page.
