This files writes the class files for the Adobe Type 1 fonts.
It uses the information in the font description files (Courier.xml, Helvetica.xml) to this
In these font description files each character is referenced by its adobe 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 charlist.xml and extracts the WinAnsi code.
