If you don't know what it does then it's best you don't install it :)

It is designed to be used by other Mods or PlugIns, so as Enigma mentions, if you don't understand or need it, don't install it...

Its primary purpose is very basic - it is to add hooks to the hook selection list in the PlugIn editor, so that the any new Mod or PlugIn can be created that can be edited in the Plugin Manager without the need to create and upload an XML file describing the hook.

It's secondary purpose is a little more interesting - it allows the content of plugin.php to be edited by a PlugIn prior to execution, thus allowing for code level edits to be performed without the administrator having to edit the php file directly. This is how the hook required for the primary purpose is inserted into the code without a file edit.

thank you!

thanks bro,
