Rmarkdown looks cool. But I think you might want to use a different tool to 
generate PDFs... they already support fonts! My plan is to use this for my UI 
framework called fidget ( 
[https://github.com/treeform/fidget](https://github.com/treeform/fidget) ). It 
turns out UI's are like 80% fonts by difficulty.
