"Write current buffer into file FILENAME.
Makes buffer visit that file, and marks it not modified.
If the buffer is already visiting a file, you can specify
a directory name as FILENAME, to write a file of the same
old name in that directory.
This makes the buffer visit that file, and marks it as not modified.
If optional second arg CONFIRM is non-nil,
ask for confirmation for overwriting an existing file.
If you specify just a directory name as FILENAME, that means to use
the default file name but in that directory. You can also yank
the default file name into the minibuffer to edit it, using M-n.
If the buffer is not already visiting a file, the default file name
for the output file is the buffer name.
If optional second arg CONFIRM is non-nil, this function
asks for confirmation before overwriting an existing file.
Interactively, confirmation is required unless you supply a prefix argument."
