This file is in charge of handling the generation of the modules list

file.

Build the modules list.

It is no mistake that the final closing parenthesis is on the

next line -- it produces proper newlines during the expansion

of `foreach'.

define FTMODULE_H_CREATE $(foreach COMMAND,$(FTMODULE_H_COMMANDS),$($(COMMAND)) ) endef

define FTMODULE_H_DONE $(OPEN_MODULE)/ EOF /$(CLOSE_MODULE) @echo done. endef

$(OPEN_DRIVER) & $(CLOSE_DRIVER) are used to specify a given font driver

in the `module.mk' rules file.

OPEN_DRIVER := $(OPEN_MODULE)FT_USE_MODULE( CLOSE_DRIVER := )$(CLOSE_MODULE)

ECHO_DRIVER := @echo "* module:$(space) ECHO_DRIVER_DESC := ( ECHO_DRIVER_DONE := )"

Each module.mk' in thesrc/*' subdirectories adds a variable with

commands to $(FTMODULE_H_COMMANDS). Note that we can't use SRC_DIR here.
