+ChangeTest - sample code to call DinkeyChange.dll in Dev-C++
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This project is written using Dev C++ 4.9.9.2 but should also work in other
+versions (for olders version you may have to create the project yourself).
+
+The source files in the project are:
+
+File name          Folder                   Description
+changetest.c       Samples\c                main source code file for C
+changetest.h       Samples\c                contains some useful constants
+libDinkeyChange.a  Samples\c\import_libs    contains the function definitions for DinkeyChange.dll
+changetest.rc      Samples\c\Visual Studio 5\DinkeyChange  resource for main dialog 
+
+Note that the source paths are structured to minimise files. If you want to
+move this project the references to these files will probably be no longer valid.
+
+The sample code contains 7 functions. Just use which ever functions are most
+appropriate and customise in your own way. The sample code is just a guide.
+As none of the parameters are sensitive then there is no need to implement
+strong security in calling DinkeyChange.
+
+Note - you will not be able to debug your program after DinkeyChange has been called.
+Our strong anti-debug code will cause the debugger to throw an exception. However,
+if you do need to debug your code you can use our debug module for DinkeyChange:
+DinkeyChangeDebug.dll. So, you can use DinkeyChange.dll for your release build
+and DinkeyChangeDebug.dll for your debug build.
+
+Note - if you are interested in creating the libDinkeyChange.a import library yourself
+then read the notes in the MinGW\Runtime\readme.txt file (Dev-C++ uses the minGW compiler).
