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 multi-
       plicative 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

NAME

       Lire::Sum - Lire class that implements the sum operator

SYNOPSIS

	use Lire::Sum

DESCRIPTION

       Class that implements the sum operator. This operator will compute the field's sum in a group of DLF records.

       It's possible to compute a weighted sum in which each value is first multiplied by the value of another DLF field.

       Its also possible to express the count as a ratio of the total count for the group or table.

METHODS

   new( %params )
       Creates a new Lire::Count object. In addition to the values supported by its parents, the weight and ratio attributes will be initialized
       to the values specified in the %params argument.

   weight( [$new_weight] )
       Returns the DLF field's name by which the values will be multiplied before being summed.

       You can change the weight field by specifying a new name as the $new_weight parameter. Use undef to remove the use of a weighting field.

   ratio([$new_ratio])
       Returns how the sum will be expressed. This can one of three possible values:

       none
	   Default. The absolute sum will be used.

       group
	   The sum will be expressed as a percentage of the group's sum.

       table
	   The sum will be expressed as a percentage of the table's total sum.
