The documentation is found in the "doc" subdirectory. To print the manual, print the file "shortsum.ps" (already in postscript format). This is the complete documentation except for the last appendix, which is not necessary for basic understanding. The complete documentation is in the file "sum.ps" (this is also explained in the README file in the directory). All subdirectories have their own private "makefile". The "makefile" at the top level goes into each subdirectory and executes that directory's "makefile". Therefore, to compile the package, or recompile after any change, just run the top level "makefile". All executable files are placed in the "bin" directory. (Make sure you read the manual before trying to use any of the executables !!!!) Example circuits can be found under the "circuits" subdirectory. If you have any problems installing the software contact: mody@poisson.usc.edu or ishwar@poisson.usc.edu
