/**
|
|
* The web entry point for all %Action API queries, handled by ApiMain
|
|
* and ApiBase subclasses.
|
|
*
|
|
* This is used by bots to fetch content and information about the wiki,
|
|
* its pages, and its users. See <https://www.mediawiki.org/wiki/API> for more
|
|
* information.
|
|
*
|
|
* It begins by constructing a new ApiMain using the parameter passed to it
|
|
* as an argument in the URL ('?action='). It then invokes "execute()" on the
|
|
* ApiMain object instance, which produces output in the format specified in
|
|
* the URL.
