Array::Compare is a Perl module which allows you to compare two arrays. It has a number of features which allow you to control the way that the arrays are compared: * white space in array elements can be significant or ignored. * particular columns in the arrays can be ignored. Additionally you can get a simple true/false return value or the number of columns which differ or an array containing the indexes of the differing columns.
