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.
