+/**
+ * The AtoB class is a utility program designed to "translate" an ASCII
+ * BASE 64 encoded blob into a BINARY BASE 64 encoded blob.  It assumes
+ * that the name of a data file is passed to the program via the command line,
+ * and that the contents contain a blob encoded in an ASCII BASE 64
+ * format.  Note that the data file may contain an optional "-----BEGIN" header
+ * and/or an optional "-----END" trailer.
+ *
+ * <P>
+ * The program may be invoked as follows:
+ * <PRE>
+ *
+ *      AtoB &lt;input filename&gt; &lt;output filename&gt;
+ *
+ *      NOTE:  &lt;input filename&gt;   must contain an ASCII
+ *                                BASE 64 encoded blob
+ *
+ *             &lt;output filename&gt;  contains a BINARY
+ *                                BASE 64 encoded blob
+ * </PRE>
+ *
+ * @version $Revision$, $Date$
