- You are not using a Gecko-based web browser. That means that this site does not look as good to you. I recommend following the Firefox link on this page (if you can see it), and downloading a secure, standards-compliant browser. If you're using Internet Explorer, you run a higher risk of getting viruses and putting up with other nonsense. If you're using a good browser, and everything appears swell (including all the rounded corners), then shoot me an email so I can fix this message.
SCP Update Script
This is a console PHP script that takes a directory structure and uploads it, excluding specified files and unchanged files, using scp. Chances are, if you're reading this, you know what scp is. If not, it's a command line utility that can copy (cp) files via a remote ssh connection. To make things simpler, look up how to make ssh bypass passwords by generating a public and private key.
