+MEMZIP - a simple readonly file system
+
+memzip takes a zip file which is comprised of uncompressed files and
+and presents it as a filesystem, allowing Python files to be imported.
+
+The script make-memzip.py takes a directory name and will create a zip file
+containing uncompressed files found in the directory. It will then generate
+a C file which contains the data from the zip file.
+
+A typical addition to a makefile would look like:
+```
+SRC_C += \
+    lib/memzip/import.c \
+    lib/memzip/lexermemzip.c \
+    lib/memzip/memzip.c \
+
+OBJ += $(BUILD)/memzip-files.o
+
+MAKE_MEMZIP = ../lib/memzip/make-memzip.py
+
+$(BUILD)/memzip-files.o: $(BUILD)/memzip-files.c
+    $(call compile_c)
+
+$(BUILD)/memzip-files.c: $(shell find ${MEMZIP_DIR} -type f)
+    @$(ECHO) "Creating $@"
+    $(Q)$(PYTHON) $(MAKE_MEMZIP) --zip-file $(BUILD)/memzip-files.zip --c-file $@ $(MEMZIP_DIR)
+```
