add a recursive target?

[Matthew R. MacIntyre]

Hi,

Is there an easy way to add a new recursive target to a top-level
Makefile.am?

For instance, I have a number of different directories with an "html"
target in them.  I'd like to have an easy way to run "make html" from
the top-level without having to maintain a special target at the
top-level.  Is this possible?

Thanks,
