+
+
+# The following variables (set by other Makefile components, in the
+# environment, or on the command line) are used:
+#
+#   BUILD_DIR      The architecture dependent directory,
+#                  e.g. `$(TOP_DIR)/builds/unix'.  Added to INCLUDES also.
+#
+#   OBJ_DIR        The directory in which object files are created.
+#
+#   LIB_DIR        The directory in which the library is created.
+#
+#   DOC_DIR        The directory in which the API reference is created.
+#
+#   INCLUDES       A list of directories to be included additionally.
+#
+#   DEVEL_DIR      Development directory which is added to the INCLUDES
+#                  variable before the standard include directories.
+#
+#   CFLAGS         Compilation flags.  This overrides the default settings
+#                  in the platform-specific configuration files.
+#
+#   FTSYS_SRC      If set, its value is used as the name of a replacement
+#                  file for `src/base/ftsystem.c'.
+#
+#   FTDEBUG_SRC    If set, its value is used as the name of a replacement
+#                  file for `src/base/ftdebug.c'.  [For a normal build, this
+#                  file does nothing.]
+#
+#   FTMODULE_H     The file which contains the list of module classes for
+#                  the current build.  Usually, this is automatically
+#                  created by `modules.mk'.
+#
+#   BASE_OBJ_S
+#   BASE_OBJ_M     A list of base objects (for single object and multiple
+#                  object builds, respectively).  Set up in
+#                  `src/base/rules.mk'.
+#
+#   BASE_EXT_OBJ   A list of base extension objects.  Set up in
+#                  `src/base/rules.mk'.
+#
+#   DRV_OBJ_S
+#   DRV_OBJ_M      A list of driver objects (for single object and multiple
+#                  object builds, respectively).  Set up cumulatively in
+#                  `src/<driver>/rules.mk'.
+#
+#   CLEAN
+#   DISTCLEAN      The sub-makefiles can append additional stuff to these two
+#                  variables which is to be removed for the `clean' resp.
+#                  `distclean' target.
+#

+#   COMPILER_SEP,
+#   LIBRARY, CC,
+#   A, I, O, T     Check `config.mk' for details.
