+/*
+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.
