       purity - a general purpose purity test


       /usr/games/purity [ flags ] [ testname ]


       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.

              r      Redraw the current question.

              q      Quit the test, and print the current score.

              ?      Print a help screen for the current prompt.

              k      Kill a section of the test.  This skips all the questions
                     of the test until the next subject heading.

              a      Toggle  answer  mode  between real answers and obfuscated
                     answers.   Real  answers  print  "yes"  and  "no",  while
                     obfuscated  answers  are "Maybe" and "maybe".  Obfuscated
                     answers are preferred if you  are  shy,  and  don’t  want
                     people to be able to read your answers over your shoulder
                     as you take the test.

              d      Toggle dERanGe output.

              s      Print your current score on the test you are taking.

              l      Toggle score logging.

       At the end of the test, your score is printed  out.   For  most  purity
       tests, lower scores denote more "experience" of the test material.


       These are the command line flags for the test.

              -a     Show  real  answers  (i.e.  "yes"  and  "no")  instead of
                     obfuscated ones (i.e. "Maybe" and "maybe") as you  answer
                     the questions.

              -d     PrINt THe tESt in DerANgeD pRInT.

              -f     Take  the  test  in  fast  mode.   Only the questions are
                     printed,  and  not  any  other  text  blocks,  like   the
                     introdution, subject headers, and the conclusion.

              -l     Take the test without having your score logged.

              -p     Print  the  test  without prompting for answers.  This is
                     useful for making hard copies of the tests without having
                     to edit out the prompts by hand.

              -r     Decrypt  the  test  using  the Rot 13 algorithm.  This is
                     done as a form of "protection", such that if you  read  a
                     rot13 test and it offends you, it’s your own fault.

              -z     zoom  through  more  prompts  in  large text blocks.  The
                     default is to prompt the user for more when  a  screenful
                     of text has been printed without any user input.


       The format of the datafiles is a very simple format, intended such that
       new tests can quickly and easily be converted to run with the test.

       There are four types of text in a purity test datafile.  Each  type  is
       contained  in  a  bracket  type of punctuation.  The definitions are as

       the styles of text blocks are:

              { plain text block }

              [ subject header ]

              ( test question )

              and  < conclusion >

       Plain text blocks are printed out character for character.

       Subject headers are preceeded by their subject numbers, starting at  1,
       and then printed as text blocks.

       Questions  are  preceeded by their numbers, and then prompt the user to
       answer the question, keeping track of the user’s current score.

       Conclusions first calculate and print the user’s score  for  the  test,
       then print out the conclusion as a text block.

       If  you  wish to include any of the various bracket punctuation in your
       text, the backslash ("\") character will escape the next character.

       To print a question with  parentheses,  you  would  use  the  following

       (have you ever written a purity test \(like this one\)?)

       the output would be this:

          1.  have you ever written a purity test (like this one)?

       and then it would have asked the user for her/his answer.

       For a generic datafile, use the "sample" datafile for the test.
