===== Plugin Specific Files =====


==== makelos ====
This is a script that is used for installing, uninstalling and testing your plugin.  Search for ''geo_kit'' in this file for places that will need modification for your plugin.  The installation script, called from this script, is what does the actual installation and uninstallation.  In this example, it is ''plugin_home/installer/geo_kit_installer.php''.

==== init.php ====
Contains code that is executed each time the user's project is started.  In some cases, it may run the plugin.<code php>
<?php

class GeoKitPlugin extends AkPlugin
{
    function load() # Executed when project is started
    {
    }
} // class GeoKitPlugin

?>
</code>



==== geo_kit_installer.php ====
This script will perform the install and uninstall of the plugin.  You will need to modify it for your plugin.  

If you have a neat piece of code for a plugin installer that you've written, please modify this entry to include your well-documented code, even though it doesn't apply to the geo_kit plugin.  

The installer is stored in ''plugin_home/installer/'' and is executed at a command line:<code>
cd project/app/vendor/plugins/geo_kit
makelos install
    or
makelos uninstall
</code>
Following is a listing of ''plugin_dir/installer/geo_kit_installer.php''.  When writing your plugin installer, you may copy, rename and modify this script.  Make sure that your ''makelos'' script points to your installer file.
