# 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'.
#
#   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.
#                  Usually empty.
#
#   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.]
#
#   FT_MODULE_LIST The file which contains the list of modules 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.
#
#   TOP_DIR, SEP,
#   COMPILER_SEP,
#   LIBRARY, CC,
#   A, I, O, T     Check `config.mk' for details.
