Export Gui style skins

I have a project with some experimental GUI skins and styles. I wonder what the easiest way is to port this to another project without having to set all the texture2D alll over again?

Select skin in project view, export a package.

Thanks Aras! When you first copy the textures to the project folder and then import the package all Texture2D settings are actually preserved. I was under the impression that the package would include the textures as well.
