I think the nearest equivalent for those running Gnome or KDE may be
"xdg-open".  So there would probably need to be a new option for specifying
the appropriate command.

Personally, I am more inclined to use "system" for executing commands,
and "browseURL" for opening documents.  "browseURL" even uses
"xdg-open" in my R installation on my Linux machine.
