How to change the default install directory

[plueders]

I have installed xampp version 1.8.2 on a server running Redhat 6.5. I was able to successfully install the software in /opt/lampp.
I have a requirement to change the install directory to /app/lampp. When I did a grep and looked for all occurances of /opt, there were way to many responses manually make the changes.
How would I modify the install script to change the install directory from /opt/lampp to /app/lampp

You cannot change it, because it is binary compiled in many modules.

Instead you can install it, rename it and finally create a symbolic link from /opt/lampp and run it from there.
