-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory. The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run. This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-# fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-# fails if $ac_aux_dir is absolute,
-# fails when called from a subdirectory in a VPATH build with
-# a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir. In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
-# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-# MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a
-# configured tree to be moved without reconfiguration.
