/*
When I started programming with Visual C++ v4.0, I missed one of my favorite
tools -- DBWIN.  Finding the code for a simple debug trace utility, DBMON,
on MSDN was a step in the right direction, but it is a console application
and thus has limited features and extensibility.  DBWIN32 is my creation
to solve this problem.

The code is essentially a merging of a stripped down version of the DBWIN code 
from VC 1.5 and DBMON.C with a few 32 bit changes.

As of version 1.2B, DBWIN32 supports both Win95 and NT.  The NT support is 
built into the operating system and works just by running DBWIN32.  The Win95
team decided not to support this hook, so I have provided code that will do
this for you.  See the file WIN95.TXT for instructions on installing this.

If you have questions, problems or suggestions about DBWIN32, I welcome your
feedback and plan to actively maintain the code.
