I am having trouble understanding what is the difference between "$variable" and
"${variable}".
I have read sh(1) and understand than ${} is a "parameter" and can contain more than
just a variable, but browsing through /etc/rc I see lots of "${variable}" (i.e. "case
${svc_val} in").
Is this just for readability or is there some functional difference?
