+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to ${srcdir}/foo.  In other projects, it is set to `.'.
+# Of course, Automake must honor this variable whenever it call a tool
+# from the auxiliary directory.  The problem is that $srcdir (hence
+# $ac_aux_dir) can be either an absolute path or a path relative to
+# $top_srcdir or absolute, this depends on how configure is run.  This
+# is pretty annoying since it makes $ac_aux_dir quite unusable in
+# subdirectories: on the top source directory, any form will work
+# fine, but in subdirectories relative pat needs to be adapted.
+# - calling $top_srcidr/$ac_aux_dir/missing would success if $srcdir is
+#   relative, but fail if $srcdir is absolute
+# - conversely, calling $ax_aux_dir/missing would fail if $srcdir is
+#   absolute, and success on relative paths.
+#
+# Consequently, we define and use $am_aux_dir, the "always absolute"
+# version of $ac_aux_dir.
