+# Minimake
+
+Minimake is a small project written in about a week in C99. Its goal was to reproduce the main features of the well known GNU Make utility.
+
+> **Note** This is a school project, therefore it probably won't interest you if you are looking for something useful.
+
+## Build
+
+```sh
+make
+```
+or even better
+```sh
+minimake
+```
+
+## How it works
+
+If you're not familiar with Make, what it does is that it reads a file named
+`Makefile` in the current directory which contains instructions to build a
+project in the form of recipes. It includes support for variables, dependencies
+, implicit rules and more.
+
+Then depending on the user input it automatically executes a recipe with its dependencies.
+
+
+Here is what a basic one can look like
+```make
+BENCH_FLAGS = --all
+
+test_and_bench:
+  bash ./runtests.sh
+  bash ./runbenchs.sh $(BENCH_FLAGS)
+```
+
+But it will more realisticly look like that
+
+```make
+CC = gcc
+CFLAGS = -std=c99 -pedantic -Werror -Wall -Wextra -Wvla
+LDFLAGS=
+
+DBG_CFLAGS = -fsanitize=address -g
+DBG_LDFLAGS= -fsanitize=address
+
+
+SRC_DIR = src
+LIB_SRCS = lines/lines.c hash_maps/hash_maps.c lists/lists.c files/files.c
+MAIN_SRCS = main.c minimake.c
+
+SRCS = $(MAIN_SRCS:%=$(SRC_DIR)/%) $(LIB_SRCS:%=$(SRC_DIR)/%)
+OBJS = $(SRCS:.c=.o)
+
+TARGET= minimake
+DBG_TARGET = minimake-dbg
+
+$(TARGET): $(OBJS)
+	$(CC) -o $@ $^ $(LDFLAGS) $(LDLIBS)
+	@echo $(OBJS)
+
+debug: CFLAGS += $(DBG_CFLAGS)
+debug: LDFLAGS += $(DBG_LDFLAGS)
+debug: $(OBJS)
+	$(CC) -o $(DBG_TARGET) $^ $(LDFLAGS) $(LDLIBS)
+
+check:
+	dash ./tests/run.sh
+
+clean:
+	$(RM) $(TARGET)
+	$(RM) $(OBJS)
+
+```
