Basically, assert does something like:

if(! foo) {
  panic;
}

assert does a test.  If the test fails, the program halts with a hopefully
useful error message.  It should be used liberally for debugging anywhere
in your code where you expect a variable to be a certain value.

That's not very well explained at all...
