436818 Create Installer Script - PHP

I need a web based installer script written in PHP that would allow me to install Wordpress but with a few changes. This install script will allow a user to install Wordpress on their site, but when installing you can pre-configure options before Wordpress is actually installed, that way once Wordpress is installed the options will already be there. Options (Besides the options Wordpress offers in their setup): - User can choose the permalink structure (Can choose from a drop down list) - User can create categories - User will be able to select a theme to be activated from a drop down list. When a theme is chosen, the script will need to copy certain files for that theme to the root of the Wordpress installation. (Each theme has different files) - User can enter API key for a plugin that will be pre-activated. The API key will be saved to the Wordpress database. - User can pre-select to activate optional plugins. If checked, the script pre-activate those plugins. - User will have an option to select which pages to auto-create. (Check box next to each page). If checked, the script will create that page. Once all the options have been selected, user clicks "Install" and there Wordpress site is installed and setup. Please PM Questions
