6 Scanning configure.ac, using aclocal

Automake scans the package’s configure.ac to determine certain information about the package. Some autoconf macros are required and some variables must be defined in configure.ac. Automake will also use information from configure.ac to further tailor its output.

Automake also supplies some Autoconf macros to make the maintenance easier. These macros can automatically be put into your aclocal.m4 using the aclocal program.
