This utility is designed to make it easier for folks to switch back and
forth between Visual Studio 2005, 2008, and 2010.  It edits the
solution (*.sln) and project files (*.csproj, *.vbproj, and *.vcproj) so
that they can be openeded by either version.

This version does not convert C/C++ projects to/from VS2010, as the the
file formats for the project file are completely different.

The installer creates a shell extension which adds an "open with" option
for the solution file.
