@echo "DESCRIPTION: "
|
|
@echo " This build system is a set of makefile modules for (GNU) Make, to "
|
|
@echo " provide a simple system for building LUFA powered applications. "
|
|
@echo " Each makefile module can be included from within a user makefile, "
|
|
@echo " to expose the build rules documented in the comments at the top of"
|
|
@echo " each build module. "
|
|
@echo " "
|
|
@echo "USAGE: "
|
|
@echo " To execute a rule, define all variables indicated in the desired "
|
|
@echo " module as a required parameter before including the build module "
|
|
@echo " in your project makefile. Parameters marked as optional will "
|
|
@echo " assume a default value in the modules if not user-assigned. "
|
|
@echo " "
|
|
@echo " By default the target output shows both a friendly summary, as "
|
|
@echo " well as the actual invoked command. To suppress the output of the "
|
|
@echo " invoked commands and show only the friendly command output, run "
|
|
@echo " make with the \"-s\" switch added before the target(s). "
