Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

	* @file
	* Helper class for encoding images as Base64.
	* Has support for the Drupal module ImageCache, just provide it with your
	* preset name if you'd like the class to use that version of an image instead.
	* Is by no means dependent on Drupal though. Just a nice feature.
	* Feel free to use it as you like.
