Robocode/Package Robot
Once you've created a robot, you can package it up to share with other people. Here's how:
Package Robot for sharing
First, select the Package robot for upload tool:

Next, select the robot you want to package. In this case, I've selected my robot "fnl.Scratch":

Click Next and fill in details about your new robot:

Click Next again, to choose a filename. The default should be fine, but remember what it says here so you can find it when you want to upload it:

Click Package! on the last page, and Robocode will package your robot for you:

That's it! You can now upload your robot's .jar file to e.g. the Robocode Repository.
