== User Information ==
Extensions are distributed separately. Drop them into this directory and enable
as per the extension's installation instructions.
You can find a list of extensions and documentation at
<https://www.mediawiki.org/wiki/Special:MyLanguage/Category:Extensions>.
== Development Information ==
If you are a developer, you might want to fetch the extension tree in another
directory and make a symbolic link:
mediawiki/extensions$ ln -s ../../extensions-trunk/FooBar
Most extensions are available through Git:
https://gerrit.wikimedia.org/g/mediawiki/extensions
Please note that under POSIX systems (Linux...), parent of a symbolic path
refers to the link source, NOT to the target! You should check the env
variable MW_INSTALL_PATH in case the extension is not in the default location.
The following code snippet lets you override the default path:
$IP = getenv( 'MW_INSTALL_PATH' );
if ( $IP === false ) {
$IP = __DIR__ . '/../..';
}
require_once "$IP/maintenance/Maintenance.php"; // a MediaWiki core file
