用于抓收到的和回别人的msg, 花了一整天的时间总算写成乐,
贴出来于大家共享.

文件名:
catchmsg.cpp
编译:
g++ catchmsg.cpp -o catchmsg
用法是这样的:
telnet bbs.your.host |catchmsg savefile
祝:
广大的热爱Linux和Unix的GGDD们和JJMM们聊天快乐,
把更多美好回忆留在按ext2格式化的硬盘上和心中.

//catchmsg.cpp
//抓取上bbs时和朋友对发的msg:)
//蜀南血梦.最后修改:1999.6.12 加入对msg镶套的支持.
//Email:blood_dreamer@126.com或BloodDreamer@263.net
//usage:
// telnet bbs.our.host |catchmsg outfile
//bugs: 未对重复的msg加以过滤;
// 抓到的msg按其出现的自然顺序组织;
// ^H和^[[?;?H尚未过滤.
