Commands in Eclipse 3.x: the 10 most common patterns

A description of the different ways of using the Command Framework in Eclipse 3.x. I think our group has used them all and I believe we've done so properly. They are:

1. Simple command with a default handler and a simple menu contribution for it.
2. Providing static parameters to commands.
3. Specifying a toggle state for a command.
4. Specifying a radio state for a command.
5. A pulldown command with sub-menu items.
6. Dynamic menu contribution.
7. Using "activeMenuSelection" in an expression.
8. Adding a control to a toolbar - not sure if we've done this but I've seen it.
9. PropertyTester.
10. Calling Command Framework API, e.g. programmatic invocation.
