==========
Structure:
==========

The library contains five folders:

  Bin
  - Contains library and example program binaries.

  Lib
  - Contains library C and C++ Header and Inline Files.
  
  Sln
  - Contains Visual Studio solutions.

  VTFCmd
  - Contains C example program source code.

  VTFEdit
  - Contains C++ .NET example program source code.

  VTFLib
  - Contains C++ library source code.

The project files are for Visual Studio .NET 2003 and 2005; no .NET extensions
are used except in VTFEdit.  Visual Studio 6.0 project files have also been
included, but nvDXTLib does not come with the correct .lib files to link with.
nvDXTLib is required for VTF creation and can be downloaded from:
