想问一下二进制协议格式说明的注释有没有什么好用的生成工具吗

比如像这种：

gzip 头的格式: +---+---+---+---+---+---+---+---+---+---+ |ID1|ID2|CM |FLG| MTIME |XFL|OS | (more-->) +---+---+---+---+---+---+---+---+---+---+ (if FLG.FEXTRA set) +---+---+=================================+ | XLEN |...XLEN bytes of "extra field"...| (more-->) +---+---+=================================+ (if FLG.FNAME set) +=========================================+ |...original file name, zero-terminated...| (more-->) +=========================================+ (if FLG.FCOMMENT set) +===================================+ |...file comment, zero-terminated...| (more-->) +===================================+ (if FLG.FHCRC set) +---+---+ | CRC16 | +---+---+ +=======================+ |...compressed blocks...| (more-->) +=======================+ 0 1 2 3 4 5 6 7 +---+---+---+---+---+---+---+---+ | CRC32 | ISIZE | +---+---+---+---+---+---+---+---+ 

纯手工感觉有点麻烦，Google 上找了一圈似乎没有现成的工具。
