purity-ng - general purpose purity testing software
]... list| FILE
Purity is an interactive purity test program with a simple, user interface and
datafile format. For each test, questions are printed to the your terminal,
and you are prompted for an answer to the current question. At a prompt, these
are your choices:
y Answer "yes" to the question.
n Answer "no" to the question.
b Backup one question, if you answered it incorrectly, or someone is watching you take the test, and you don't (or do) want to admit a different answer.
s Print your current score on the test you are taking.
q Quit the test, and print the current score.
? Print a help screen for the current prompt.
At the end of the test, your score is printed out. For most purity tests, lower
scores denote more "experience" of the test material.
