-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.
