+============================================================
+OID Converter: OID encoder/decoder
+v1.3 - Matthias Gaertner 1999/2001 - Freeware
+============================================================
+
+The OID converter is a handy little tool to convert ASN.1 OIDs from readable dotted decimal notation to binary hexadecimal Distinguished Encoding Rules (DER) representation and vice versa. 
+If you're into x.509 certificates, this may be useful to you, too.
+
+Usage:
+ OID [-c|-C] [-o] {-i|1.2.3.4}
+   converts dotted form to ASCII HEX DER output.
+ OID -x [-o] {-i|hex-digits}
+   decodes ASCII HEX DER and gives dotted form.
+   
+If you need more information, please refer to Matthias Gaertner's page,
+http://www.rtner.de/software/oid.html
