Dan, by "except for the documentation part", I meant generating
.Rd files (the LaTeX-like syntax) automatically from some org-syntax
that does *not* depend on code blocks.  I.e., it would be cool to
specify syntax like I have above for documentation.  Using org-mode
headlines for each section like Description, Usage, Arguments, etc.

Just like exporting to LaTeX generates sections, some process would
use these headlines to generate the .Rd sections.

That way, you don't have to use the .Rd syntax yourself.  No big deal,
just a convenience feature.  I don't know how you'd specify to org-mode
that a particular subtree was to generate .Rd syntax, and I don't know
if it would be on export or tangling.

An alternative is simply just to use code blocks of type Rd within
org-mode and then tangle to .Rd files.  That's what I currently do.

Hope that explains it,
Erik
