Is there anything we can do to the autoconf documentation to make this
point more clear?  We do want to support both camps of users - those who
use just autoconf (and edit aclocal.m4), and those who use automake (who
edit acinclude.m4 or dump files in the m4 include directory), and the
documentation should make it clear which approach a developer should use
based on the tools they are currently using.
