usage="Usage: R SHLIB [options] files

Build a shared library for dynamic loading from the specified source or
object files (which are automagically made from their sources).  If not
given via \`--output', the name for the library is determined from the
first file.

Options:
  -h, --help		print short help message and exit
  -o, --output=LIB	use LIB as (full) name for the built library
  -v, --version		print version info and exit

Report bugs to <R-bugs@lists.r-project.org>."
