45.Sh DESCRIPTION
46The
47.Nm
48utility tests your knowledge of random facts.
49It has a database of subjects from which you can choose.
50With no arguments,
51.Nm
52displays the list of available subjects.
53.Pp
54The options are as follows:
55.Bl -tag -width indent
56.It Fl t
57Use tutorial mode, in which questions are repeated later if you didn't get
58them right the first time, and new questions are presented less frequently
59to help you learn the older ones.
60.It Fl i
61Specify an alternate index file.
62.El
63.Pp
64Subjects are divided into categories.
65You can pick any two categories from the same subject.
66.Nm Quiz
67will ask questions from the first category and it expects answers from
68the second category.
69For example, the command ``quiz victim killer'' asks questions which are
70the names of victims, and expects you to answer with the cause of their
71untimely demise, whereas the command ``quiz killer victim'' works the
72other way around.
73.Pp
74If you get the answer wrong,
75.Nm
76lets you try again.
77To see the right answer, enter a blank line.

MD
79The index and data files have a similar syntax.
80Lines in them consist of several categories separated by colons.
81The categories are regular expressions formed using the following
82meta-characters:
83.Pp
84.Bl -tag -width "pat|pat" -compact -offset indent
85.It pat|pat
86alternate patterns
87.It {pat}
88optional pattern
89.It [pat]
90delimiters, as in pat[pat|pat]pat
91.El
92.Pp
93In an index file, each line represents a subject.
94The first category in each subject is the pathname of the data file for
95the subject.
96The remaining categories are regular expressions for the titles of each
97category in the subject.
98.Pp
99In data files, each line represents a question/answer set.
100Each category is the information for the question/answer for that category.
101.Pp
102The backslash character (``\e'') is used to quote syntactically significant
103characters, or at the end of a line to signify that a continuation line
104follows.
105.Pp
106If either a question or its answer is empty,
107.Nm
108will refrain from asking it.
109.Sh FILES
110.Bl -tag -width /usr/share/games/quiz.db -compact
