now let's try to catch the whole site, because my FreeBSD is installed in VMware, and NO x is installed at all. Usually I use Putty to connect to the FreeBSD in VMware through SSH, freeBSD in VMware also launched its own ftpd service.
put
Emacs User's Guide address: http://www.cbi.pku.edu.cn/chinese/documents/csdoc/emacs/
in the file get, upload the FTP file to BSD and execute
% wget -- input-file get-M
in a short time, complete the 10 HTML files.
