Problem with argument parsing

[lgwe]

I have a python-script: myscript, used to start a program on another
computer and I use OptionParser in optpars.
I use it like this: myscript -H host arg1 -x -y zzz
I would like OptionParser to ignore all arguments after arg1, because
these are options that should be used by the program started on the
oter computer arg1 -x -y zzz.
One solution is to write: myscript -H host "arg1 -x -y zzz"
But is it in some way possible to instruct OptionParser to ignore -x -
y zzz without  the "..."?
