The tools module comes with a handful of custom admin tools. Some of these include:
1) A system function you can use to tell where a page is located, differentiating between local pages, system pages, and shared pages.
2) A phpinfo function you can use to view php settings.
3) A script to archive and extract plugin install pages. There are also a couple utilities used to setup the chat engine at the click of a button.
4) A language creator that works with GoogleTranslate to jumpstart creation of additional language packs in 80+ languages.
