If you are PHP developer you must know that PHP can be used for writing desktop applications. If you have Linux box you can write scripts on PHP and run them without starting browser. That makes this simple programming language even more valuable. Ok, lets imagine that you have created a PHP script with MySQL support and 20-50 classes and include files in different folders. Now, you want to send your script somewhere, sharing it with the world. I hope you dont expect your end users be so advanced that they would have to go into your code to edit your configurations like names of files with data, name of the database used, username and password for MySQL access. You would probably want some more simplicity in installation process of your script. And here it comes a little script that will generate installation script for your PHP software.
