  *
  * MIB compiler (code generator):
  * ------------------------------
- * - Provided in lwIP contrib repository.
- * - Written in C#. MIB viewer used Windows Forms.
+ * - Provided in contrib dir.
+ * - Written in C#. MIB viewer using Windows Forms.
  * - Developed on Windows with Visual Studio 2010.
  * - Can be compiled and used on all platforms with http://www.monodevelop.com/.
  * - Based on a heavily modified version of of SharpSnmpLib (a4bd05c6afb4)
  *   (https://sharpsnmplib.codeplex.com/SourceControl/network/forks/Nemo157/MIBParserUpdate).
+ *   This has been the last known revision of that code before being converted to
+ *   closed source. The new code on github has completely changed, so we can not
+ *   just update :-(
  * - MIB parser, C file generation framework and LWIP code generation are cleanly
  *   separated, which means the code may be useful as a base for code generation
  *   of other SNMP agents.
