NuProj is a Visual Studio project type that lets you create NuGet packages. You can easily build the resulting solution using MSBuild.
NuProj adds a new project type to Visual Studio that let's you build NuGet packages.
Referencing other projects (such as C# and VB projects). This will cause their project outputs to be packaged under the lib folder. NuProj takes care of figuring out the right lib folder name, such as net45. It will also promote any NuGet referenes to proper dependencies in the resulting .nupkg file. You can also reference other NuProj projects which allows you to declare dependencies to packages that are part of the same solution.
Manual mantained content. You can also add content directly to the project. In that case, you'd simply use folders in the Visual Studio project to control how the content is packaged. For example, in order to get an install script, you'd create a tools folder and within that you'd add the install.ps1 file.
Producing symbol packages. You can easily create symbol packages. Optionally, you can also include the sources. In this case, NuProj will use the PDB information to find the source files and embed them in the resulting .nupkg file.
Build servers such as Visual Studio Online. The build integration is also available separately and can be checked in or restored as a NuGet package. For details, check out the documentation.
