Xah,

thanks for the helpful links -- also thanks to other folks who have been
helping on this thread.  I think i have two questions, so i'll write
them in two seperate emails.

I have a python script that queries my evolution database and returns a
series of lines, with one address per line:

matt@gont:~$ python evo-query.py matt
 14 matches in 874 entries

(note the not-so-well-maintained duplicates!)

i've written a short function based on one of your examples that grabs
this output -- i imagine it needs some fixing up, but here it is:
(defun query-python-addressbook (name)
  (interactive "s To:" )
  (setq cmd-name "python /home/matt/evo-query.py")
  (setq sh-output (shell-command-to-string (concat cmd-name " " name)))
  (message "%s" sh-output)
  )

(query-python-addressbook "matt") now returns a message with the this
text.  instead i'd like it to return a list of names.  i'm sure someone
will point me to the right info node, but i'm having some difficulty
navigating the immense amounts of documentation -- is there a simple way
to take each line of a text block and turn it into a list of lines?  

thanks much! -- second quesiton to follow...
