/**
 * This file is the entry point for all API queries.
 *
 * It begins by checking whether the API is enabled on this wiki; if not,
 * it informs the user that s/he should set $wgEnableAPI to true and exits.
 * Otherwise, it constructs a new ApiMain using the parameter passed to it
 * as an argument in the URL ('?action=') and with write-enabled set to the
 * value of $wgEnableWriteAPI as specified in LocalSettings.php.
 * It then invokes "execute()" on the ApiMain object instance, which
 * produces output in the format specified in the URL.
