Manual talk:$wgExtensionFunctions

When are these functions called?
I am trying to determine at what point the extension set up functions in the  array are actually called. Could somebody please clarify? Thanks. --Wikitonic 18:44, 20 June 2008 (UTC) | Update: Nevermind, I thought "setup.php" referred to the setup file for the extension, not the one for MediaWiki itself in . --Wikitonic 18:47, 20 June 2008 (UTC)

When is this preferred over inline setup code?
It would be interesting to read an explanation of when to use this hook vs. simply including the setup code at the top level of MyExtension.php. --Lil Devil 06:51, 29 May 2010 (UTC)
