[Rd] Rscript on Windows

ActivePerl has '-x' switch which tells it to skip all lines in the file till
This allows writing perl scripts in ordinary .bat files.
?shQuote contains a link with the following perl script example:
:: Windows executable Perl script
:: assumes perl.exe is in path
:: otherwise, use absolute path
perl -x -S "%0" %*
print "Hello, World!\n";
:: ------ end of hello.bat ------
" -x " (lower case x): Skip all text until shebang line.
" -S " (upper case S): Look for script using PATH variable. Special meaning
in Windows: appends .bat or .cmd if lookup for name fails and name does not
have either suffix.
" %* " only on WinNT/2K/XP; use %1 %2 . . . %9 on Win9x/DOS
I think the simplest way to implement shebang on windows would be embedding
one more command line switch with similar functionality to perl's '-x'.
