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

Compile the specified files for subsequent collection into a shared
library using 'R CMD SHLIB' or an executable program using 'R CMD
LINK'.  Currently, the following languages with associated source file
extensions are supported (provided that the respective compilers are
available and R was configured to use these): C ('.c'), C++ ('.cc' or
'.cpp'), fixed-form Fortran ('.f'), free-form Fortran ('.f90' or'.f95'),
Objective C ('.m'), and Objective C++ ('.M' or '.mm').

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

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

Report bugs at <https://bugs.R-project.org>."
