You will have to adjust the classpath to the names of the actual JAR files in the lib directory.
avalon-framework.jar is necessary only for versions 0.20.5 or later.
xml-apis.jar, xercesImpl.jar and xalan.jar are not necessary for JDK version 1.4 or later.</note>

+ <note>The tool will construct some values (FontBBox, StemV and ItalicAngle) based on assumptions and calculations which are only an approximation to the real values.
FontBBox and Italic Angle can be found in the human-readable part of the PFB file or in the AFM file.
The PFMReader tool does not yet interpret PFB or AFM files, so if you want to be correct, you may have to adjust the values in the XML file manually.
The constructed values however appear to have no visible influence.</note>

Currently, this embedded font contains only the minimum data needed to be embedded in a pdf document, and does not contain any codepage information.
The PDF document contains indexes to the glyphs in the font instead of to encoded characters.
-While the document will be displayed correctly, the net effect of this is that searching, indexing, and cut-and-paste will not work properly.

- One workaround for this behavior is to use the -ansi option when generating metrics with TTFReader.
