/*
* NetBeans Debugging Tools. What are these tools and why are they important?
* 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 starup 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.
