Looking for Unix style 'getopt' command line parsing in a Windows batch file

Question

Can anyone help me find something to parse command line args in a Windows batch file like one would do in a Unix shell script using getopt/getopts? It doesn't have to be all Posix-y; just something that I can specify what switches I expect, which of them require/allow an argument. They don't need to be "long" switches; single characters will work.

It can be an external .exe that the batch file calls. It has to be freely distributable.

You can you something like this (-h has no args, hence no shift after that, -b and -s take additional args, so shift them).

:GETOPTS
 if /I "%1" == "-h" goto Help
 if /I "%1" == "-b" set BASE=%2 & shift
 if /I "%1" == "-s" set SQL=%2 & shift
 shift
if not "%1" == "" goto GETOPTS
