Makefile

## NRC Makefile

# This makefile was thrown together by khhs in the span of 10 minutes.
# Due to this, it's not the most well written thing in the world.
# But it still "works", and it does some stuff which I've never tried before.

## LICENSE

# Feel free to use it in your own projects, I do not guarantee any form
# of warranty tho.

# All I'd want you to do is to allow others to also use it, in OSS projects.
# You should also credit me(khhs)

# Just don't be an ass, okay?

## Variable descriptions

# 	BIN - The output/binary directory
# 	EXE - The binary file
# 	MODS - All the source directories(under src)
#	CPY - All ".cgen.py" files, which are python scripts that generate C code
#	HPY - All ".hgen.py" files, which are python scripts that generate C headers
# 	SRC - All the files that should be compiled
# 	HDR - All the header files in the project
#	DEPS - Auto-generated C dependencies
# 	OBJ - The object files
# 	MKDIR - The command used to create a dir(without error)
# 	RM - The command used to delete files/dirs(without errors)
# 	CP - The command used to copy files
# 	CC - The C compiler command
# 	LD - The C linker command
#	CCFLAGS - The C compiler flags
#	LDFLAGS - The C linker flags
#	LIBRARY - The C linker libraries
#	FLAGS - Various flags that may be set for compilation.

## Targets

#	$(BIN) - Makes the build directory
#	buildfiles - Copies C and header files to build dir
#	obj - Builds C files into .o
#	binary - Links the .o files into the $(EXE) file
#	all - Build everything(binary)
#	run - Builds and runs the project
#	clean - Deletes the build directory
#
#		Special targets:
#	%.c: %.cgen.py - Generates a C file from a C generator
#	%.h: %.hgen.py - Generates a H file from a header generator
