Not sure about that, would need some investigating. From what I 
can tell, dub docs have improved quite a bit in the past year.

Sorry, let me rephrase. What I meant is that, with dub, you can 
add dependencies (e.g. some http library) and define D versions. 
So even tho it's only a single file, the invocation of dmd alone 
is not sufficient to understand the code completely. I guess it 
would be most useful if I created some test cases and documented 
them.

Haven't experimented with it yet so it's all just speculation so 
far. I'm quite interested in a dub linter. As far as I can tell 
from a first glance at your plugin code, it doesn't seem too 
complicated. I think I will investigate whether dub is suitable 
for this endeavor and implement that aspect of the plugin myself. 
If I have enough time in the coming days, of course. Will keep 
you posted!
