#  Instructions:
#  -------------
#  Copy ths file (ns-2.28_install.sh)
#  to your $HOME directory and "cd" to your $HOME 
#  directory
# 
# % chmod 700 ns-2.28_install.sh
# % sh ns-2.28_install.sh
#
# This will create a directory by name "ns-allinone-2.28" in your home
# directory, and create links to the main NS-2 source directories.  
#
# The "ns" executable is in the directory ~/ns-allinone-2.28/ns-2.28
#
# You can now proceed with any changes to the source in your 
# directory. To make changes to an existing file 
# (say tcp-reno.cc) you will have to
# first delete the link from your <$HOME>/ns-allinone-2.28/<subdir> 
# directory, copy the file
# from the original source into your <$HOME>/ns-allinone-2.28/<subdir>
# directory and then work on it.
#
# After you are done with your changes, run "make" and a 
# new "ns" will be created in your ~/ns-allinone-2.28/ns-2.28 directory.
# Use this to run your test tcl scripts
#
# For example, if you want to modify tcp-reno.cc, you would do
#
# % cd ~/ns-allinone-2.28/ns-2.28/<subdir>
# % rm tcp-reno.cc
# % cp <SOURCE_LOCATION>/tcp-reno.cc .
# % vi tcp-reno.cc ;# make changes to the file
# % cd ~/ns-allinone-2.28/ns-2.28
# % make
