<!-- This file writes the class files for the fonts (Courier.java,
Helvetica.java etc.). It uses the information in the font
description files (Courier.xml, Helvetica.xml) to do this. In these
font description files each character is referenced by its adobe
glyph name:
<char name="A" width="667"/>
To resolve this name and to find the code for this character it looks
up the adobe name in the file encodings.xml and extracts the appropriate
code. -->
