There is something I'd like to see documented in Automake, or even
with some ``official'' support: the standard way to express computed
dependencies.  I'm very interested in this because, honestly, it's
been a long while since I want to add something like -MD to autom4te.
And I sure for some other frameworks people have similar tools.  We
all have the same issue to address, and therefore there is certainly
something to factor :)
