usage="Usage: R CMD COMPILE [options] files

Compile the specified files for subsequent collection into a shared
library using 'R CMD SHLIB'.  Currently, C, C++, and FORTRAN files
(with extensions '.c', '.cc' or '.cpp' or '.C', and '.f', respectively),
are supported.

Options:
  -h, --help		print short help message and exit
  -v, --version		print COMPILE version info and exit

Other options of the form '-DMACRO' or 'VAR=VALUE' are passed on to the
compilation.

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