 Vim, set the 'autoread' option.  This doesn't work at the moment you write the
 file though, only when the file wasn't changed inside of Vim.
 
+If you do not want to be asked or automatically reload the file, you can use
+this: >
+	set buftype=nofile
+
+Or, when starting gvim from a shell: >
+	gvim file.log -c "set buftype=nofile"
+
 Note that if a FileChangedShell autocommand is defined you will not get a
 warning message or prompt.  The autocommand is expected to handle this.
