elisp from CL transition guide

[Tamas Papp]

Hi,

I have some Common Lisp programming experience, and would like to use
Emacs Lisp for simple tasks.  I found introductions to Elisp, but what
I am looking for is some guide that would tell me the differences from
CL, to get started quicker.  I already found that there is no
defparameter or format etc.  Is there some page where these
differences are listed?

Thanks,

Tamas
