1. Create a directory called "tcpXX", where XX is the topology number assigned
to you in the first project. E.g., if you were assigned topology 13, the directory name should be
"tcp13".

2. Copy to the directory your source files, including:

    - tcpXX/Makefile. Typing "make" should compile the router binary called
      "sr"; typing "make clean" should clean up the binary and the object files.

    - source code. everything needed to compile the binary.

    - tcpXX/README.txt. If there's anything you want me to know in grading your
      project, put it in this file.
       
3. Create a tarball 

   cd tcpXX
   make clean
   cd ..
   tar -zcf tcpXX.tgz tcpXX

4. Email tcpXX.tgz to me before the deadline.
