# DO NOT INVOKE THIS MAKEFILE DIRECTLY!  IT IS MEANT TO BE INCLUDED BY

# OTHER MAKEFILES.

# 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//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,

# Makefile after all other rules have been included.
