ent applies various tests to sequences of bytes stored in files and
reports the results of those tests. The program is useful for evaluating
pseudorandom number generators for encryption and statistical sampling
applications, compression algorithms, and other applications where the
information density of a file is of interest.  Tests performed include
Entropy, Chi-square, Arithmetic Mean, Monte Carlo value for Pi, and
Serial Correlation Coefficient.
