%% Bloody useful
-define(IF(Test,True,False), case Test of true -> True; false -> False end).

%% ?WHEN_OPT(Option, Options, Fun) -> ok.
%% ?UNLESS_OPT(Option, Options, Fun) -> ok.
%%  Call Fun when Option is/is not a member of Options.

-define(WHEN_OPT(Opt,Opts,Fun), ?IF(member(Opt, Opts), Fun(), ok)).

%% -define(UNLESS_OPT(Opt,Opts,Fun), ?IF(member(Opt, Opts), ok, Fun())).

-define(DEBUG(Format,Args,Opts),
        ?WHEN_OPT(debug_print, Opts,
                  fun () -> lfe_io:format(Format, Args) end)).
