[Bioc-devel] System Requirements for imported packages

Hi All,

I'm curious what the preferred method is for dealing with System 
Requirements originating from an imported package. For example, if I had 
a package that imported `biomaRt` which itself imports `XML` which has 
the SystemRequirement `libxml2` how is that dealt with? Are package 
installers expected to troubleshoot this (via install messages), should 
I put this requirement and install instructions for `libxml2` in a 
README for my package?

Thanks for any input,
