+# Wrapper script for use of the tsocks(8) transparent socksification library
+#
+# There are three forms of usage for this script:
+#
+# /usr/bin/tsocks program [program arguments...]
+#
+# This form sets the users @LD_PRELOAD@ environment variable so that tsocks(8) 
+# will be loaded to socksify the application then executes the specified 
+# program (with the provided arguments). The following simple example might 
+# be used to telnet to www.foo.org via a tsocks.conf(5) configured socks server:
+#
+# /usr/bin/tsocks telnet www.foo.org
+#
+# The second form allows for tsocks(8) to be switched on and off for a 
+# session (that is, it adds and removes tsocks from the @LD_PRELOAD@ environment
+# variable). This form must be _sourced_ into the user's existing session
+# (and will only work with bourne shell users):
+#
+# . /usr/bin/tsocks on
+# telnet www.foo.org 
+# . /usr/bin/tsocks off
+# 
+# Or
+# 
+# source /usr/bin/tsocks on
+# telnet www.foo.org
+# source /usr/bin/tsocks off
+#
+# The third form creates a new shell with @LD_PRELOAD@ set and is achieved
+# simply by running the script with no arguments 
+# 
+# /usr/bin/tsocks
+#
+# When finished the user can simply terminate the shell with 'exit'
+# 
+# This script is originally from the debian tsocks package by 
+# Tamas Szerb <toma@rulez.org>
