NAME

       booldnf - converts a boolean expression to the DNF

SYNOPSIS

       echo 'a&(!b|c&!d)' | booldnf > result.txt

DESCRIPTION

       booldnf  is  a program that reads boolean expressions from its standard input and rewrites
       them in Disjunctive Normal Form on its standard output.  It uses the BoolStuff library.

       The Disjunctive Normal Form is an ORing of ANDed terms.  In other  words,  if  the  OR  is
       considered an additive operation and the AND a multiplicative operation, then the DNF is a
       sum of products.

       Each expression must be on its own text line.  Variable names must  be  composed  only  of
       ASCII letters and digits.

       The  AND  operator is &, the OR operator is |, and the NOT operator is !.  Parentheses are
       allowed.

       The command flushes its output buffer after each result or error  message,  to  make  sure
       that  it  can  be  used  with bidirectional pipes.  Results and error messages always take
       exactly one text line.

EXAMPLES

       The command

              echo 'a&(!b|c&!d)' | booldnf

       should display

              a&c&!d|a&!b
