Why do I need both AC_INIT and AM_INIT_AUTOMAKE???

[Dr. David Kirkby]

I have a configure.ac file. Unless I have both AC_INIT and
AM_INIT_AUTOMAKE, automake complains

i.e. starting like this is okay, but there seems duplication of the
package name, my email address and version number:

AC_PREREQ(2.57)
AC_INIT(atlc, 4.2.12, address@hidden)
AM_INIT_AUTOMAKE(atlc, 4.2.12, address@hidden)

yet removing 'AM_INIT_AUTOMAKE' prevents the configure script from
being generated - see below, despite the fact I have run 'aclocal',
which is from automake 1.7 and not an old version of automake I have
lying around as the error message suggests. 

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

sparrow /export/home/davek/atlc % automake
configure.ac: `AM_INIT_AUTOMAKE' must be used
automake: your implementation of AM_INIT_AUTOMAKE comes from an
automake: old Automake version.  You should recreate aclocal.m4
automake: with aclocal and run automake again.
