It is natural, and job control is the most natural way to do it. If you
don't want to use job control for some reason, the `setpgid' loadable
builtin exists, as others have noted.

If you don't want to use the loadable builtin, you can easily write a
standalone program that, when executed, becomes a process group leader
and execs the remaining arguments.
