I don't see how realpath can do what I want. relpath.py gives me the
relative path of a from b. But realpath doesn't do so.

/tmp$ mkdir a b
/tmp$ relpath.py a b
../a
/tmp$ realpath -s a b
/tmp/a
/tmp/b


Also, from the manpage "realpath converts each filename argument to an
absolute pathname, ".

Would you please show me how to use realpath to compute the relative path?
