GSL for Microsoft Visual C++ (Windows)

[Brian Gough]

I've built a self-installing version of GSL for Microsoft Visual C++.

It is at http://www.network-theory.co.uk/gsl/ in the file setup.exe if
anyone wants to try it out.

The installation includes a demonstration workspace in the \demo
subdirectory which you can use as a quick check (the default location
is C:\Windows\Program Files\GSL-0.9.1+\demo\).  There is a README.txt
file with the expected output in the same directory.
