anchor.diff:  session doesn't crash if icewm does (should never happen). You can
   restart icewm from there or start some other window manager. The
   session will close if you close the xterm.
  -
  -The above should work for most Linux systems.
  -If you are running xdm or some other login program
  -check it's manpage for the correct place to start the window manager
  -(usually `~/.xsession`, `~/.Xsession` or `~/.xinitrc`).

  This document is the documentation for the *IceWM* X11 window manager.
  It is still incomplete. IceWM and its documentation is
  
negative.code: `icewm-session` binary instead of pure `icewm`. Note that this is
  not a complete Session Manager but it helps to automate the startup.
  
  First make sure that you choose the correct
  http://www.tldp.org/HOWTO/XWindow-User-HOWTO/runningx.html[X startup]
  script in your home directory.
  For most distributions either the file `$HOME/.xsession`
  or `$HOME/.xinitrc` is honored by startx and X display managers like KDM.
  On RedHat, the `$HOME/.Xclients` may be used instead.
  In all cases, choose the one
  recommended by your distribution and make sure that there
  is no concurrency between the X startup scripts.
  Ensure that the script is executable. 
  Mine looks something like this:
  
  ....
  #!/bin/bash
  # run profile to set $PATH and other env vars correctly
  . $HOME/.bash_profile
  # setup touchpad and the external mouse
