+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:

+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.
