These files are used by a program called aclocal (part of the GNU automake
package).  aclocal uses these files to create aclocal.m4 which is in turn
used by autoconf to create the configure script at the the top level in
this distribution.

The Makefile.am file in this directory is automatically generated
from the template file, Makefile.am.in.  The generation will fail
if you don't have all the right tools.
