-# SYNOPSIS
-#
-#   AX_ENABLE_BUILDDIR [(dirstring-or-command [,Makefile.mk [,-all]])]
-#
-# DESCRIPTION
-#
-#   If the current configure was run within the srcdir then we move all
-#   configure-files into a subdir and let the configure steps continue
-#   there. We provide an option --disable-builddir to suppress the move into
-#   a separate builddir.
-#
-#   Defaults:
-#
-#     $1 = $host (overridden with $HOST)
-#     $2 = Makefile.mk
-#     $3 = -all
-#
-#   This macro must be called before AM_INIT_AUTOMAKE. It creates a default
-#   toplevel srcdir Makefile from the information found in the created
-#   toplevel builddir Makefile. It just copies the variables and
-#   rule-targets, each extended with a default rule-execution that recurses
-#   into the build directory of the current "HOST". You can override the
-#   auto-dection through `config.guess` and build-time of course, as in
-#
-#     make HOST=i386-mingw-cross
-#
-#   which can of course set at configure time as well using
-#
-#     configure --host=i386-mingw-cross
-#
-#   After the default has been created, additional rules can be appended
-#   that will not just recurse into the subdirectories and only ever exist
-#   in the srcdir toplevel makefile - these parts are read from the $2 =
-#   Makefile.mk file
-#
-#   The automatic rules are usually scanning the toplevel Makefile for lines
-#   like '#### $host |$builddir' to recognize the place where to recurse
-#   into. Usually, the last one is the only one used. However, almost all
-#   targets have an additional "*-all" rule which makes the script to
-#   recurse into _all_ variants of the current HOST (!!) setting. The "-all"
-#   suffix can be overriden for the macro as well.
-#
-#   a special rule is only given for things like "dist" that will copy the
-#   tarball from the builddir to the sourcedir (or $(PUB)) for reason of
-#   convenience.
