Newcomers often ask "What can I work on in language //foo//". We should have easier way(s) for them to find out.
Most of our extensions are in PHP/JavaScript, so it's not worth adding anything specifically in the {{extension}} infoboxes.
Instead, we should go through the other tools, and make sure they are listed in the existing (or new) per-language sections and pages.
E.g. mw:Huggle should be linked from mw:Python or mw:API:Client_code or similar.
Likely targets:
* https://www.mediawiki.org/wiki/API:Client_code
* https://www.mediawiki.org/wiki/Python , https://www.mediawiki.org/wiki/Perl , and other (?) language-specific pages
Likely sources of info:
* https://www.mediawiki.org/wiki/Manual:Coding_conventions
* https://www.mediawiki.org/wiki/Template:Conventions_navigation
* https://www.mediawiki.org/wiki/How_to_become_a_MediaWiki_hacker
* https://www.mediawiki.org/wiki/Development_statistics -- (is there anything in here (or elsewhere), that is better than openhub? https://www.openhub.net/orgs/wikimedia/projects is in the right direction, but is too simplified and partially inaccurate (e.g. huggle is not written in visual basic, it's in C++ and Python) and is incomplete.)
