no, there's not. however, rio is a thread-library program and you can't just
exec() out without confusing other processes you're sharing memory with.
rio already has a hook where it will provide an Exit menu option if ".out"
appears somewhere in argv[0]. so, you could have an rc script named rio,
and rename rio to rio.out. the rc script would just need to read something
like
#!/bin/rc
while()
rio.out $*
