Greg Beaver - Do you develop a website? It is infinitely better to synchronize live and development sites using the PEAR Installer:

"This is the missing piece of the 4 most common synchronization methods: it's really hard to fix mistakes made. You will still make mistakes when using the PEAR Installer, the difference is that reverting them is a 1-liner and requires no sweat or fear that one will break something else in the process: each release of a package is a known quantity, and it will work the same way as it did last time."
