usage="Usage: R CMD SHLIB [options] files|linker options

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

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

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