<!-- 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. -->
