Writing code to be copy and pasted is a bad idea anyway. It just invites
unsuspecting users that do not understand what ramifications can come
from running code they don't understand. A simple slip of the mouse
could cause someone great grief. Lets not forget too... some
terminals/web browsers and other forms of text transportation can copy
in different ways, inserting control characters that you don't see the
results before running. But this is an rc.d example soooo $() should be
fine as its reccomended more often than not.
