DataWorks Database Format 1.0
==============================================
-Extension should be .dwf
+Extension SHOULD be .dwf
All numbers MUST use big-endiam
Index entry (`indexentry`) MUST be in this format:
flag : 1 byte uint8_t
count : 8 bytes uint64_t
-dbname_len : 8 bytes uint8_t
+dbname_len : 1 byte uint8_t
dbname : 256 bytes ASCII
fields : 4096 bytes ASCII (Separate field names using NUL. Put NUL twice on the last field name.)
.PHONY: all clean
.SUFFIXES: .c .o
-OBJS = parser.o util.o dataworks.o
+OBJS = parser.o database.o util.o dataworks.o
all: $(LIB_PREFIX)dataworks$(LIB_SUFFIX)
