[NTLUG:Discuss] A few Debian questions

[Courtney Grimland]

I'm new to Debian, but so far I love it.

1) Where does the 'fortune' program get installed?  I've apt-get'ed
fortunes, fortune-mod, fortunes-off, and I can't seem to find where it
put the actual fortune binary.

2) Is there a way, either with apt-cache or dpkg, to list what files
will be installed from a given package, and where they will go?  I'm
looking for something analogous to "rpm -ql <name>" or "rpm -qlp
<filename>".

3) What is the proper way to specify programs to start when X is
started?  Debain seems to use a SysV-init style mechanism in
/etc/X11/Xsession.d so that both xdm and startx do the same thing.
 But I don't understand what exactly goes in that directory, or in
/etc/X11/Xsession.

4) I'm looking to have xscreensaver start like this:
http://www.jwz.org/xscreensaver/man1.html#8
but I don't understand how to do it in the proper Debian way.  There is
no /usr/lib/X11/xdm/Xsetup file.  Do I create it?  Has it been renamed
or merged with another file?
