nuspec file for SMS

Just a trial one... Didn't want to create more than this.... just in case you didn't want to nuget them all!

To get this working you need to build all - use the batch build menu in VS - then pack.bat and then push.bat

To push you need your API key setup from nuget.org `NuGet SetApiKey Your-API-Key` from http://docs.nuget.org/docs/creating-packages/creating-and-publishing-a-package
