Quiz tells a correct answer whenever you type a bare newline. At the end of input, upon interrupt, or when questions run out, quiz reports a score and terminates.

The -t flag specifies `tutorial' mode, where missed questions are repeated later, and material is gradually introduced as you learn.

The -i flag causes the named file to be substituted for the default index file. The lines of these files have the syntax:

line = category newline \(bv category `:' line
category = alternate \(bv category `|' alternate
alternate = empty \(bv alternate primary
primary = character \(bv `[' category `]' \(bv option
option = `{' category `}'

The first category on each line of an index file names an information file. The remaining categories specify the order and contents of the data in each line of the information file. Information files have the same syntax. Backslash `\\' is used as with sh (1) to quote syntactically significant characters or to insert transparent newlines into a line. When either a question or its answer is empty, quiz will refrain from asking it.
