This file contains a summary of what you will find in each of the files that
make up your xp_blowfishencrypt application.

xp_blowfishencrypt.vcproj
    This is the main project file for VC++ projects generated using an Application Wizard. 
    It contains information about the version of Visual C++ that generated the file, and 
    information about the platforms, configurations, and project features selected with the
    Application Wizard.

xp_blowfishencrypt.cpp
    This is the main dll source file.
