 778 dnl
 779 dnl To be used in configure.in of any project using Bakefile-generated mks
 780 dnl
 781 dnl Behaviour can be modified by setting following variables:
 782 dnl    BAKEFILE_CHECK_BASICS    set to "no" if you don't want bakefile to
 783 dnl                             to perform check for basic tools like ranlib
 784 dnl    BAKEFILE_HOST            set this to override host detection, defaults
 785 dnl                             to ${host}
 786 dnl    BAKEFILE_FORCE_PLATFORM  set to override platform detection
 787 dnl
 788 dnl Example usage:
 789 dnl
 790 dnl   AC_BAKEFILE([FOO(autoconf_inc.m4)])
 791 dnl
 792 dnl (replace FOO with m4_include above, aclocal would die otherwise)
 793 dnl (yes, it's ugly, but thanks to a bug in aclocal, it's the only thing
 794 dnl we can do...)
