-/**
- * FontChecker.
- *
- * <PRE>
- * This is a FontChecker program. This class is a "parent" process
- * which invokes a "child" process. The child process will test
- * series of fonts and may crash as it encounters invalid fonts.
- * The "parent" process must then interpret error codes passed to it
- * by the "child" process and restart the "child" process if necessary.
- *
- * usage: java FontChecker [-v] -o outputfile
- *
- *        -o is the name of the file to contains canonical path names of
- *           bad fonts that are identified. This file is not created if
- *           no bad fonts are found.
- *        -v verbose: prints progress messages.
- *
- * </PRE>
