In this type of projects we need to:
1) perform AOT-compilation
2) install documentation (.xml files, generated .html files)
3) optionally do tests
4) provide an ability to build library with debug symbols
5) install library into file system, and provide the way to reuse library from other packages
6) provide a .pc -file (for pkg-config) to allow to populate monodevelop's "References"->"Packages" tab
7) provide an ability to sign and install into GAC
8) provide an ability to create a local .nupkg (which may require writing .nuspec file)
