Open terminal window from emacs

[Frederik <freak.fred@gmail.com>]

Hey,

I try to open up urxvt from emacs and make the terminal emulator
automatically switch to the current working directory of the current
buffer (i.e. to the value of default-directory).

This is what I've come up with:

(call-process "/usr/bin/urxvt" nil 0 nil
	(concat "-cd" default-directory))

But this doesn't work.

This
(call-process "/usr/bin/urxvt" nil 0 nil
	"-cd ~/test")
doesn't work either, even though the directory exits.

Any pointers?
