- * 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.
