+# Neat little script for easy use of lbxproxy with ssh.
+# Based on this: http://www.gelatinous.com/aaron/tips/lbxproxy
+# and adapted by Jonas Smedegaard <dr@jones.dk>
+
+# Changes from original script:
+#  * Instead of another custom script "remote-frame", simply open a
+#    terminal and quit lbxproxy on exit.
+#  * Ssh compression and X forwarding is explicitly enabled.
+#  * Path to lbxinit is not hardcoded - just place this script somewhere
+#    in your path.
+#  * Get rid of "l" and "r" options (more intuitively in my opinion).
+
+# The following is from the web page:
+
+# How do I get lbxproxy to work with xauth/ssh? I can't connect.
+#
+# I kept trying to get lbxproxy to work over ssh, or even just with
+# plain xauth. The only way I could make it work was with 'xhost +'.
+# Finally I found an article by a Ted Rathkopf that showed me a way to
+# make it work. If you are getting access control problems to your X
+# server, here's what you need to do.
+#
+# Instead of just extracting your cookie or attempting to use the ones
+# that ssh creates for you, you must get your real xauth key over to the
+# target and fudge it so that the display entry is adjusted for the
+# proxy (:63 by default).
+#
+# Example:
+#
+# On my DSL host, I use 'lbxinit r ' (r is for remote). This causes an
+# 'lbxinit l ' on the remote host -- (l is for local). Yeah, there are
+# easier ways to do this, but I wanted to have one script I could copy
+# around.
+#
+# [the script itself]
+#
+# Hey, what's remote-frame?
+#
+# You need to start some long-running X app in the local section or else
+# lbxproxy gets huffy and quits after the first client exits, even
+# though the man page says otherwise. So, I open up a frame of my emacs
+# on that host.
+#
+# I turned off compression with -nocomp because ssh does its own stream
+# compression. You might need to enable it with the -C argument to ssh.
+#
+# The last thing I did was make an 'lbx' shell alias that sets my
+# DISPLAY environment to :63.
