Examples of dub use needed

[Guido via Digitalmars-d]

Dub doesn't really work like other package managers. When I load 
a package:

dub fetch scriptlike

It stores it someplace and doesn't say where. You have to run 
'dub list' to figure out where. That's is very different than 
other packages. It deserves a bigger mention in the meager 
documentation.

I've been trying to init a project using the command

dub -init -f sdl trickproject
-or-
dub -f sdl -init trickproject

and nothing seems to parse.

So, I look at the source code for the format option and see this:
args.getopt("f|format", &m_format, [
     "Sets the format to use for the package description file. 
Possible values:",
     "  " ~ [__traits(allMembers, PackageFormat)].map!(f => f == 
m_format.init.to!string ? f ~ " (default)" : f).join(", ")
]);

It doesn't look straightforward at all. Not sure why there is so 
much complexity on this particular commandline option, but 
shouldn't these command options work the way I have them?

In the interactive mode, I get to make the selection for the 
project file format. I don't see many examples of how to use 
options.
