NAME
       Affix::Infix2Postfix - Perl extension for converting from infix
       notation to postfix notation.

SYNOPSIS
	 use Affix::Infix2Postfix;

	 $inst=Affix::Infix2Postfix->new(
	   'ops'=>[
		 {op=>'+'},
		 {op=>'-'},
		 {op=>'*'},
		 {op=>'/'},
		 {op=>'-',type=>'unary',trans=>'u-'},
		 {op=>'func',type=>'unary'},
		],
		 'grouping'=>[qw( \( \) )],
		 'func'=>[qw( sin cos exp log )],
		 'vars'=>[qw( x y z)]
		);
	 $rc=$inst->translate($str)
	 || die "Error in '$str': ".$inst->{ERRSTR}."\n";

DESCRIPTION
       Infix2Postfix as the name suggests converts from infix to postfix
       notation. The reason why someone would like to do this is that postfix
       notation is generally much easier to do in computers. For example take
       an expression like: a+b+c*d. For us humans it's pretty easy to do that
       calculation.  But it's actually much better for computers to get a
       string of operations such as: a b + c d * +, where the variable names
       mean put variable on stack.
