    -h 帮助  
    -i 源码目录，input  
    -o 输出文件或目录，output  
    -p 包前缀  
    -x 不包括文件夹或文件，如果你有些源文件不想被编译进去的话，将会用到这个参数  
    -m 编译模式：zip（zip压缩格式）、files（离散文件）  
    -e 加密模式：xxtea_zip（对zip包进行 xxtea 加密）、xxtea_chunk（对.luac 进行加密）  
    -ek 加密密钥  
    -es 加密签名  
    -ex 编译后的文件的后缀名  
    -c 从一个文件加载参数列表  
    -q 生成过程不输出信息  
compile mode:  
    -m zip (default)    package all scripts bytecodes to a ZIP archive file.  
    -m c                package all scripts bytecodes to a C source file.  
    -m files            save bytecodes to separate files. -o specifies output dir.  
encrypt mode:  
    -e xxtea_zip        encrypt ZIP archive file with XXTEA algorithm,  
    -e xxtea_chunk      encrypt every bytecodes chunk with XXTEA algorithm.  
                        * default encrypt sign is "XXTEA"  
                        * output file extension name is "bytes"
