Difference between pkg fetch -a and pkg fetch -d?

[c083d4]

According to the man page, pkg fetch -a fetches all the packages, and pkg fetch -d fetches the packages and its dependencies as well.

So, what is the difference?
Doesn't "all packages" mean that it 'll also fetch the dependencies?
:/

By "all", they might mean every package in the repository, not just any named on the command line.

lol, I didn't think about that. And... Is there a way I can download an entire package category? Like, for example, Emulators? I know I can fetch the folder directly from the ftp, but I'd like to use pkg because it tells me the total size of the download...
P.S.: Yes, I hate compiling from source, and love binary packages.
