+/** @defn AliDebug
+ @param N Debug level - always evaluated
+ @param A Argument Form(including paranthesis) - the message to
+ print. Note, that @a A should contain balanced paranthesis, like
+ @verbatim
+ AliDebug(1, Form("Failed to decode line %d of %s", line, filename));
+ @endverbatim
+ The point is, if the current log level isn't high enough, as
+ returned by the AliLog object, then we do not want to evalute the
+ call to Form, since that is an expensive call. We should always
+ put macros like this into a @c do ... @c while loop, since that
+ makes sure that evaluations are local, and that we can safely put
+ a @c ; after the macro call. Note, that @c do ... @c while loop
+ and the call with extra paranthis, are an old tricks used by many
+ C coders (see for example Bison, the Linux kernel, and the like).
