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

ns-2.1b7
-----------

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.

ns-2.1b9
--------

Use the ns-2.1b9-atm.patch for patching the atm module into the
ns-2.1b9 directory.  Follow steps:

    Download the atm patch to a directory in which ns-2.1b9 is a
    subdirectory (place ns-2.1b9 and the patch at the same level in
    the directory tree).

    cd ns-2.1b9
    patch -p1 -i ../ns-2.1b9-atm.patch


2)A simple 

     ./configure
     make
     make install

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