You can now use the commands @code{ybuffer-list} and
@code{ysave-buffer} to list and save buffers. The @code{ysave-buffer}
command takes a buffer number (as listed by @code{ybuffer-list}) and a
file name to which to write the buffer contents. You should use a
file name which does not already exist; no backups of the previous
contents of the file will be saved, if any.
Then type the command @code{ybuffer-list} to see which buffers are
available. For each buffer, it lists a buffer number. To save a
buffer, use @code{ysave-buffer}; you specify the buffer number, and
the file name to write that buffer into. You should use a file name
which does not already exist; if the file does exist, the script does
not make make a backup of its old contents.
