Files:

MANIFEST		this file
makedepend*		used to make dependencies
makefile		makefile
nm.awk			awk file for parsing output of nm
simulate*		simulate binary

Directories:

kernel/			standard set of functions used by REAL
sources/		code for data sources 
router/			code for router nodes
lang/			files for interpreting NetLanguage
scenarios/		scenarios used in proposed benchmark
ecn/			input files for simulation exercises to be used with my book

The two directories below contain non-essential code (i.e.,  not linked
in to the simlator code in the current makefile)

distrib/		files for creating distributed version of REAL
etc/			useful files that are not directly used by REAL
