questions about dub

[thorstein via Digitalmars-d-learn]

Hi,

I have questions regarding the usage of 'dub'. I'm learning D 
under Win7. I have installed VisualD for the community edition of 
Visual Studio and got some file i/o working.

Next I would like to continue with the mir-tools for matrix 
manipulation. I understood that I have to build them first using 
dub. But I didn't succeed:

C:\..\AppData\Roaming\dub>dub fetch mir-algorithm
Fetching mir-algorithm 0.1.1...
Please note that you need to use `dub run <pkgname>` or add it to 
dependencies of your package to actually use/run it. dub does not 
do actual installation of packages outside of its own ecosystem.

C:\..\AppData\Roaming\dub>dub run mir-algorithm
Building package mir-algorithm in 
C:\..\AppData\Roaming\dub\packages\mir-algorithm-0.1.1\mir-algorithm\
Fetching mir-internal 0.0.5 (getting selected version)...
Main package must have a binary target type, not sourceLibrary. 
Cannot build.

Thats where I stuck.

Beside my specific problem of how to start with the mir-tools I 
wonder how and for what purpose 'dub' is applied when building 
projects in connection with Visual Studio? Or is it just a more 
light-weight command line build tool?

Thanks for shedding some light!
