On Windows, there is some POSIX shell functionality, but I have never 
seen anyone use that.  Most people who are doing this kind of thing have 
installed Cygwin or the MKS Toolkit.  For the rest of the Windows 
masses, it would have to be something like (really rusty since I haven't 
done NT or OS/2 programming this millennium):

rem Sweave.cmd
set R_EXE="%R_HOME%\bin\rterm.exe"
echo library("utils"); Stangle("%1%") | %R_EXE% --no-save --no-restore 
--quiet
