> We have different forms of quoting in the shell script. We should pick a
> consistent policy and follow that.
> Specific areas of concern around backticks and {{$(...)}}
> Solaris 10 is known to have a true BourneShell which does not understand
> {{$(...)}} but the backtick style is very hard to quote effectively
