LISP Project...

I've been trying to learn lisp recently, and I've been able to type things into the interpreter and get it to spit out sane results, however...

I don't know how to create any kind of little compiled program using the language.  None of the tutorials I've read show anything about how to get input from the console or any shit like that, none of them show you where the equivalent of void Main () is, (though I think they might just execute linearly...  defun seems to just apply to anything that comes after it) they mostly just describe the language without telling you how to do anything.

Does anyone know where I can download lisp projects that I can compile and pull apart, to examine how they work etc...?

C++ would be so much more useful if it were dynamically typed, dynamically bound, reflexive, garbage collected, and had native heterogeneous lists and dictionaries. If we follow this reasoning we get to Python, Ruby and others, which are as nice to work with as we want, but not yet efficient enough for what we want to do with them :( .
