Adding a TrueType font

I needed to add a .ttf font for a presentation I was working on, it turned out to be a lot more hassle than it needed to be.

$ mkdir ~/.font  
$ cp font.ttf ~/.font/
$ mkfontdir ~/.font  
$ fc-cache

I read a lot about editing xorg.conf to change font paths, in the end it was a matter of refreshing the font cache and restarting evince.
