[R] several package building questions

[Edna Bell]

Dear R Gurus:

I have several package building questions, please:

a.  Where do you find the list of keywords needed for the help files, please?
b.  I'm using a SuSe Linux system at the moment.  How do I download
the help manuals, please?
c.  What is the command (not in R) to compile Fortran code to be used
with R, and eventually be used in a package, please?  It used to be
something like g77 -O2 -c test.f?

Thanks for any help.

Sincerely,
Edna Bell
