content is $-doubled (unless it contains &$- to turn that off)
- Together &:macro and &${...} provide a more reasonable macro
- facility than raw make. They solve the problem that make
- expansions cannot directly generate multiple rules, variable,
- etc.; instead, `$(eval )' must be used, but that re-expands
- the argument, meaning that all the literal text must be
- $-doubled. This applies to the macro text and to the
- arguments. Also `$(eval $(call ...))' is an unfortunate syntax.
- Hence &:macro and &${...}.
