=head1 NAME

Automake::Configure_ac - Locate configure.ac or configure.in.

=head1 SYNOPSIS

  use Automake::Configure_ac;

  # Try to locate configure.in or configure.ac in the current
  # directory.  It may be absent.  Complain if both files exist.
  my $filename = find_configure_ac;

  # Likewise, but bomb out if the file does not exist.
  my $filename = require_configure_ac;

In both cases, the name of the file found is also put in the
C<$configure_ac> global variable.
