# Makefile for library building,written by Yu-Cheng Chang
# Date: Tue 03-06-2001
#
# Desc: 1.To change this makefile to build another library ,
#       those MACROs are need to be modified.
#        LIB_F: the file name of library.
#        OBJS: the object files of library.
#        INCS: include files.
#              (one of those files is modified,all objects are rebuild)
#        SRC_DIR: Directoris of source code.
#                 (each directory is seperated with space)
#        INC_DIR: Directoris of include files.
#                 (each directory is seperated with space)
#        OBJ_DIR: Directory to place object code(one directory ONLY)
#        LIB_DIR: Directory to place library file(one directory ONLY)
#
#       2.Modifing MACROs below is according to your requirement.
#        PRE_SYM: The defined symbols for preprocessor.
