949/*
950When I started programming with Visual C++ v4.0, I missed one of my favorite
951tools -- DBWIN. Finding the code for a simple debug trace utility, DBMON,
952on MSDN was a step in the right direction, but it is a console application
953and thus has limited features and extensibility. DBWIN32 is my creation
954to solve this problem.
955
956The code is essentially a merging of a stripped down version of the DBWIN code
957from VC 1.5 and DBMON.C with a few 32 bit changes.
958
959As of version 1.2B, DBWIN32 supports both Win95 and NT. The NT support is
960built into the operating system and works just by running DBWIN32. The Win95
961team decided not to support this hook, so I have provided code that will do
962this for you. See the file WIN95.TXT for instructions on installing this.
963
964If you have questions, problems or suggestions about DBWIN32, I welcome your
965feedback and plan to actively maintain the code.
