I recently started playing with lisp in ubuntu and decided to go with slime for it. So i installed slime through ubuntu software manager, couldn't find it, couldn't start it (i'm totally new to emacs and slime). After that I read some manuals, made changes to .emacs config and eventually installed slime using emacs and its package manager. Now i'm wondering if i have 2 versions of slime where are they located, which one is being actually used etc.
