NAME

       eancheck - check digit validator for EAN, PLU and UPC barcode numbers

SYNOPSIS

       eancheck [EAN code, PLU code or UPC prefixed with 0]

DESCRIPTION

       eancheck  takes  a 13 digit EAN (European Article Number, aka a barcode number) or a 4 digit PLU code and
       runs some simple maths upon it to discover the "check digit". It then  compares  this  against  the  last
       number  of the inputted EAN to check whether that code; if they match, then the EAN/PLU is valid. If they
       do not, then the opposite applies.

BUGS

       Right now UPC codes need to be prefixed with a zero (i.e turned into EAN codes) to be properly checked.
