Thanks for the PR. Some of your edits are very linux (not all shells start their command lines $) or even Debian/Ubuntu centric (apt-get install...). pydeps runs very well on Windows (the only platform where I use it), and if I add the ubuntu/debian command to install graphviz I would probably need to add the yum/pacman/dnf/zypper/emerge commands too -- and none of those would help BSD or Windows users...

[mchlnix]

I thought of that, too and I guess it is your choice how you want to go about it. You can revert some of the changes if you want. While I'm pretty linux centric, I just wanted something to denote, that this is a shell command. I guess you could also use "> " to make it a bit more platform independent. I actually don't know what a windows shell looks like. :)

Edit: And of course apt-get is pretty debian centric, but I think people who are interested in your project can probably figure out, that they have to substitute something. I meant it more as a signal to "package manager install" graphviz however you like. Debian's way just happened to be my default.
