It'd be great if the Fontain "Fonts" folder was a seperate folder in your Addons directory rather than being embedded in the Fontain folder. Not sure if this is possible, but by splitting it out, it'd be easier for people to update Fontain without overwriting any custom fonts they've added.

Example:
Fontain includes a new addon folder called "Fontain_Fonts" (or even better, the "Fontain_Fonts" is distributed as a separate package), which contains all the actual fonts files as well as the catalog.lua.
