# The following variables (set by other Makefile components, in the
# environment, or on the command line) are used:
#
# BUILD 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.
#
# 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,
# LIBRARY, CC,
# A, I, O, T Check `config.mk' for details.
# The targets `objects' and `library' are defined at the end of this
# Makefile after all other rules have been included.
