This isn't a plugin, just an updated installation process.
No more editing or renaming of files, just copy all the contents to your traq folder, and open the install in your browser.
* System checks (php & mysql version, folder permissions)
* Database Details
* System Details
* Error handling
* Automatically creates configuration file
* Checks if traq is already installed. If it is, disable installation
* If configuration file doesn't exist, automatically navigate to installation folder
This update requires an override of the default index.php (in the root directory), but if you don't want to override the core file, just navigate to http://www.YOURSITE.com/traq/install (or where ever you installed traq)
