PractRand includes several programs that use the library to do useful things:
1. RNG_output
	A command-line driven program.  This takes an RNG name and an number of 
	bytes on the command line and prints out that many raw random bytes to 
	stdout.  For use in unix-like environments where the output might be piped 
	somewhere useful.  It has an optional third parameter to specify the seed 
	to use.  The seed should be a 64 bit integer expressed in hexadecimal.  If 
	no seed is specified it will pick one at random.  
	The number of bytes to output can be replaced with "inf" (without the 
	quotes) to cause it to emit random bytes indefinitely.  This is desirable 
	if the output is being piped to a program and you don't know exactly how 
	many bytes that program will use before closing the pipe.  
		example - using the RNG named "jsf32", generate about 1.1 terabytes, 
		using a randomly generated seed
			./RNG_output jsf32 1234567890000
2. RNG_test
	This command-line driven program applies PractRand statistical tests to an 
	RNG.  Anomalous test results will be reported to the user.  The definition 
	of 'anomalous' for this purpose is adjustable from the command line, as is 
	the choice of which RNG to test and which set of tests to use.  An external 
	RNG can be used if its output is piped in through stdin.  A file can be 
	used if it is piped in through stdin.  
	This program also has alternate modes that allow it to test seeding or 
	entropy pooling quality instead of simple RNG output.  It works by 
	generating a random sequence of seeds with minimal hamming distance from 
	each other, seeding the targetted RNG with them, generating 64 bits of RNG 
	output using each seed, and concatonating those sets of 64 bits in to a 
	stream of data that is tested as if it were produced by an RNG.  
	Sample command lines for use on linux:
		testing a PractRand RNG:
			./RNG_test jsf32
		testing a file:
			cat random_data_file | ./RNG_test stdin
		testing data piped in from RNG_output:
			./RNG_output jsf32 inf | ./RNG_test stdin32
	Sample command lines for use on windows:
		testing a PractRand RNG:
			RNG_test jsf32
		testing a file:
			RNG_test stdin < random_data_file
		testing data piped in from RNG_output:
			RNG_output jsf32 inf | RNG_test stdin32
3. RNG_benchmark
	Measures speeds of all recommended RNGs and all candidate RNGs.  
	Candidate RNGs may get an unfair advantage depending upon how this 
	program gets linked, as they are in the same compilation unit.  
	Non-recommended RNGs are not optimized and are not benchmarked.
4. Test_calibration
	Various bits of code used during calibration of the tests.  Not coherently 
	organized atm.  Not intended for end users, but included as partial 
	documentation for the calibration process used on the tests.
