Hi, 

The idea there, is to be able to convert both html (generated by a rich 
text editor)  and markdown (or other similar markup language) file through 
a similar pipeline to a pdf with similar style. Using a different 
templating engine somewhere in the pipeline mean more complexity, so i'm 
considering the idea of using pandoc templating if the html result is okay.

Thanks.
