Info files in Windows and Mac distributions

Recently I installed Linux on my desktop.  I discovered that R for Linux ships with info files of manuals.  R for Windows and Mac only ship with html and pdf files of manuals.

Why not include info files in R distributions for Windows and Mac?  These are very convenient with emacs.  Using pandoc , I tried converting from html to info.  The results were nowhere near as good as the originals.

I think the answer to the question is just that there isn't much demand 
for them:  emacs is mainly used by Linux users these days.

But the source to the manuals is available, so presumably you could 
produce these pretty easily yourself.  The R-devel versions are here:

I don't know whether the .texi files are sufficient for emacs or whether 
you need to process them first; I'm not an emacs user.
