"[+DESCRIPTION?\btest\b evaluates expressions and indicates its "
"results based on the exit status. Option parsing is not "
"performed so that all arguments, including \b--\b are processed "
" as operands. The evaluation of the "
"expression depends on the number of operands as follows:]{"
"[+0?Evaluates to false.]"
"[+1?True if argument is not an empty string.]"
"[+2?If first operand is \b!\b, the result is True if the second "
"operand an empty string. Otherwise, it is evaluated "
"as one of the unary expressions defined below. If the "
"unary operator is invalid and the second argument is \b--\b,"
"then the first argument is processed as an option argument.]"
"[+3?If first operand is \b!\b, the result is True if the second "
"and third operand evaluated as a unary expression is False. "
"Otherwise, the three operands are evaluaged as one of the "
"binary expressions listed below.]"
"[+4?If first operand is \b!\b, the result is True if the next "
"three operands are a valid binary expression that is False.]"
