+ * There are two main tools here. The first tool is a tool for delaying or
+ * stopping gvim during startup. The second tool is a protocol log tool.
+ *
+ * The startup delay tool is called nbdebug_wait(). This is very important for
+ * debugging startup problems because gvim will be started automatically from
+ * netbeans and cannot be run directly from a debugger. The only way to debug
+ * a gvim started by netbeans is by attaching a debugger to it. Without this
+ * tool all startup code will have completed before you can get the pid and
+ * attach.
+ *
+ * The second tool is a log tool.
+ *
+ * This code must have NBDEBUG defined for it to be compiled into vim/gvim.
