usage="Usage: R CMD LINK [options] linkcmd

Perform the specified linkcmd by passing it through GNU libtool and

setting a few useful R-related options.  Use in particular when creating

executables linked against the R shared library, in which case linkcmd

must contain '-lR' but need not specify its library path.

Options:

  -h, --help            print short help message and exit

  -v, --version         print version info and exit

Currently only is useful when creating executables, and only works if

the C compiler is used for linking.  If FORTRAN code is to be linked, it

needs to be manually ensured that the linker flags for the FORTRAN 77

intrinsic and run-time libraries are present.  C++ is not supported

(yet).

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