How do you store third party libraries in your source control?

Question

How do you store third party libraries that you use in your project in your source control?

When would you store binaries in your source control?

When would

Answer 1

It depends on how big they are. When binaries or installers are too big, it can cause havoc for remote users. The upside of storing binaries and installers is that everything a developer needs to get up and running is in source control and the versions are correct. If you have a separate installation location, versions can get messed up. So, in general I like to store small or moderate binaries in source control, but larger ones I leave out.

Edit: Oh, and I call mine "BinRef" :)
