What is meant by <<! ... ! ??

I tried typing it into google but no results. I don't know what it's called or what it does and when it is used so I must ask:

What does it mean if you have something like...

cmd <!!
cm2
cm3
!

What do those <!! and ! symbols do? When/why do you use them?
I found it inside a bourne shell script.
