A good description of what "re-prebinding" is and why you would want to do it appears here:

http://macusertalk.com/discuss/lofiversion/index.php/t119.html

The basic gist of it is that your applications may launch faster and the system may run better overall if you periodically re-prebind things.

The script below, when executed with administrator permission, will re-prebind all the software on your boot drive, potentially improving performance.

The script was designed for and tested on OS X 10.3.x and may or may not work with earlier or later OS X releases.  As with all my scripts, by downloading and attempting to use them you agree to accept all responsibility and liability for whatever may happen.  That means if you run this script and your system wipes its hard drive, catches fire, and burns down your entire city (highly unlikely) or anything else goes wrong, you agree that I'm not responsible.  I don't support or warranty these scripts in any way. I just share them here in the hope that they'll help others.
