So then it will just pass all the arguments passed to that script to dmd. Cant really tell without more info on how it's called, but that's what it'll do.

Passes '-L.' to the linker. :D I can see that, but what does '-L.' mean exactly? It adds '.' to the list of directories which the linker will search when looking for the required libraries.

Re: Linker command
It compiles the example code and links it with supplied libraries, supposedly dallegro bindings.
