Hi all. I'm trying to figure out how to install the wkhtmltopdf application (available through apt-get, homebrew, etc) for generating PNG files from raw HTML (for Plots). I don't want to force the dependency as part of a standard install... if users want to add it then they can output PNG for Plotly, but it should (IMO) be a conditional dependency.
I do, however, want to use it as part of the regression testing on Travis, and that means it should be installed, but not through a standard BinDeps method. For any dependency/travis wizards... what's my best course of action? Thanks, Tom
