# 1. Create a new directory to install ns-related software. Make sure that you are in
#    this directory. Save this install script there, set
#    the file permission to executable and run the script. Ex:

#	% chmod +x install-linux.sh
#	% ./install-linux.sh

# 2. It will create a directory tree:


# 3. 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 ns-2 directory, copy the file
#    from the original source into your ns-2 directory
#    and then work on it.

# 4. After you are done with your changes, run "make" and a new ns will be
#    created in your ns-2 directory. Use this to run your test tcl
#    scripts
