Shairon Toledo's RGhost [1] is a superb Ruby library for developers
wanting a quick and easy way to generate PDF files.

The latest version of the library has a BWIPP-based adapter called
rghost-barcode [2] that makes it simple to include barcodes into your
documents.

It's a excellent new frontend to our PostScript library which provides
a very powerful and intuitive API that expresses BWIPP's main features
- congratulations and thanks to Shairon!

I sure that many in our PS barcoding community will find it very useful.

Have fun,

Tez
