Overview

This script converts an ASCII type braille file into a PEF 2008-1 document.

What is PEF?

The Portable Embosser Format (PEF) is a data format for representing braille books, accurately and unambiguously. PEF can be used for braille embossing and archiving anywhere in the world, no matter where nor how it was produced. PEF is a digital braille hardcopy - the PDF of braille books, if you will.

For more information, see Introduction to PEF.

Input Requirements

This script accepts plain text files where each braille character is represented by some other character. The most commonly used representation is "North American Ascii Braille".

In addition to the characters used to represent braille, the file may contain newline and form feed characters.

Output

The output is a PEF 2008-1 document.
