Slim is a lightweight login manager based on GNUstep's Login.app
It makes a great replacement for XDM for those who want something
that looks good, but still do not want Gnome or KDE.

This package also includes a BSD-style rc.d script to start slim;
you will need to make /etc/rc.d/rc.slim executable:
   chmod 755 /etc/rc.d/rc.slim

Also, you will need to add something like this to /etc/rc.d/rc.local:
  if [ -x /etc/rc.d/rc.slim ]; then
    /etc/rc.d/rc.slim start
  fi

Note that your system should use runlevel 3 for this to work.
I (rworkman) did a bit of tinkering to try and make slim work properly
from runlevel 4 (starting it from rc.4) a few versions ago, but I was
not successful, and it wasn't worth the effort to continue.

Finally, if you have PAM installed and wish to build slim with support
for it, have a look inside the build script for instructions; otherwise,
it will work as is.
