+This is an implementation of the basE91 encoder and decoder in Java.
+
+Syntax:
+ java -jar base91.jar [OPTION] infile [outfile]
+
+Options:
+
+-d decode a basE91 encoded file;
+ all non-alphabet characters (such as newlines) are ignored
+
+-u leave encoder output unformatted;
+ i. e., disable line wrapping after 76 characters
+
+-h display short help and exit
+
+-V output version information and exit
+
+
+If no outfile is given for encoding, it defaults to `infile_b91.txt' (or to
+`infile.b91' with the `-u' switch).
+On decoding, the added file extension is removed to generate the name for
+outfile; otherwise, if infile hasn't a default extension, the decoded data is
+written to `infile.bin'.
+
+For further information visit the basE91 home page at
+http://base91.sourceforge.net/
