Steps for compiling the ATM simulator
-------------------------------------

I have assumed here that tcl8.3.2/tk8.3.2, otcl version 6, tclcl version 10
are all previously installed on your current directory.  

1) Untar and unzip the ns-2.1b7 version on to this directory.  
   tar xvzf ns-2.1b7.tar.gz

2) Then cp your atm patch to the directory you have ns-2.1b7 directory.
   Untar and unzip the patch
    tar xvzf ns-2.1b7-atm-patch.tgz

3)cd into ns-2.1b7

4)A simple 

     ./configure
     make
     make install

   should get you going.  If not, check all your paths for the TCL, OTCL
   and TCLCL.

   Read the installation instructions from the NS home page for more details.
