title: R help page as object
body: <p>Is there a nice way to extract get the R-help page from an installed package in the form of an R object (e.g a list). I would like to expose help pages in the form of standardized JSON or XML schemas. However getting the R-help info from the DB is harder than I thought.</p>
  
  <p>I hacked together a while ago to get the HTML of an R help manual page. However I would rather have a general R object that contains this information, that I can render to JSON/XML/HTML, etc. I looked into the <code>helpr</code> package from Hadley, but this seems to be a bit of overkill for my purpose.</p>
