opts="--restore --save --no-readline"

usage="Usage: R CMD BATCH [options] infile [outfile]

Run R non-interactively with input from infile and place output (stdout

and stderr) to another file.  If not given, the name of the output file

is the one of the input file, with a possible '.R' extension stripped,

and '.Rout' appended.

Options:

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

  -v, --version		print version info and exit

  --			end processing of options

Further arguments starting with a '-' are considered as options as long

as '--' was not encountered, and are passed on to the R process, which

by default is started with '$opts'.

See also help(BATCH) inside R.
