So I have been trying to figure out what #pragma does. It looks like it calls some libraries but I am not sure. If it is calling libraries, what are available libraries for use and what do these libraries do?
Thanks in advance everyone!

pragma is a pre-compiler directive. ie it tells the compiler what to do or how to behave.
eg #strict - "be uptight when you compile this schizzle bro!"
They're also very helpful in optimizing your game.
how are they helpful in optimizing?
by being strict. they won't allow you to do as dirty code.
e.g. when defining a variable without #pragma you can leave out the typing and unity will figure out what the variable 's supposed to be when you use it. But the 'figuring out'-part can take a lot of resources. That's why it's considered bad habit / dirty code to not always type stuff. With #pragma you must tell of what type the variable will be and it will give you an error if you don't comply.
Greta, now I now... the new version of MonoDevelop includes #pragma strict on all new scripts. This will keep me on my toes ;-)
It's Unity 3.5 that includes #pragma strict for new scripts, not MonoDevelop.
