+#
+# SYNOPSIS
+#
+#   AC_DEFINE_DIR(VARNAME, DIR [, DESCRIPTION])
+#
+# DESCRIPTION
+#
+#   This macro sets VARNAME to the expansion of the DIR variable,
+#   taking care of fixing up ${prefix} and such.
+#
+#   VARNAME is then offered as both an output variable and a C
+#   preprocessor symbol.
+#
+#   Example:
+#
+#      AC_DEFINE_DIR([DATADIR], [datadir], [Where data are placed to.])
