+/* gdbserve.c -- NLM debugging stub for Novell NetWare.
+
+ This is originally based on an m68k software stub written by Glenn
+ Engel at HP, but has changed quite a bit. It was modified for the
+ i386 by Jim Kingdon, Cygnus Support. It was modified to run under
+ NetWare by Ian Lance Taylor, Cygnus Support.
+
+ This code is intended to produce an NLM (a NetWare Loadable Module)
+ to run under Novell NetWare. To create the NLM, compile this code
+ into an object file using the NLM SDK on any i386 host, and use the
+ nlmconv program (available in the GNU binutils) to transform the
+ resulting object file into an NLM. */
