[slime-devel] Slime and the default pathname basic question

Hi everybody i have some basic slime/lisp question. Normally if i start lisp from the command line in a particular directory, this directory is set as the default path in the lisp interpreter. So i can load any other file in the same directory simple by (load "filename"). In emacs slime, as soon as i start the slime-mode the default path is set to my linux home directory (i checked it in *default-pathname-defaults*). So my question is, what is the most straightforward method to set up slime (or lisp, or my lisp file) in such a way, that the default path is set to the currently loaded file? Many thanks matus
