 Note that this function cannot correctly handle binary files
 (specifically, files containing C<\0> character which is treated
-as end of string).  For those you need to use the C<read_file>
+as end of string).  For those you need to use the C<download>
 function which has a more complex interface.
 
 Because of the message protocol, there is a transfer limit 
 of somewhere between 2MB and 4MB.  To transfer large files you should use
 FTP.
