 \section{Standard module \sectcode{uu}}
 \stmodindex{uu}
 
 This module encodes and decodes files in uuencode format, allowing
 arbitrary binary data to be transferred over ascii-only connections.
+Whereever a file argument is expected, the methods accept either a
+pathname (\code{'-'} for stdin/stdout) or a file-like object.
 
-The \code{uu} module defines the following functions:
-
-\renewcommand{\indexsubitem}{(in module uu)}
+Normally you would pass filenames, but there is one case where you
+have to open the file yourself: if you are on a non-unix platform and
+your binary file is actually a textfile that you want encoded
+unix-compatible you will have to open the file yourself as a textfile,
+so newline conversion is performed.
 
-\begin{funcdesc}{encode}{filename\, mode\, in_file\, out_file}
-Uuencode file \var{in_file} into file \var{out_file}. Both are
-file-like objects supporting a \var{read} and \var{write} method
-respectively. The uuencoded file will have the header specifying
-\var{filename} and \var{mode} as the defaults for the results of
-decoding the file.
-\end{funcdesc}
+This code was contributed by Lance Ellinghouse, and modified by Jack
+Jansen.
 
-\begin{funcdesc}{decode}{filename\, mode\, in_file}
-Note that this function uses a non-standard form of variable
-arguments, see below for other variants of argument lists.
+The \code{uu} module defines the following functions:
 
-This call decodes uuencoded file \var{in_file} (an object supporting a
-\var{readline} method), placing the result on a file with name
-\var{filename} and mode \var{mode}.

-\begin{funcdesc}{decode}{in_file\, out_file}
-An alternative form of \var{decode} which writes the resulting data to

+\begin{funcdesc}{encode}{in_file\, out_file\optional{\, name\, mode}}
+Uuencode file \var{in_file} into file \var{out_file}.  The uuencoded
+file will have the header specifying \var{name} and \var{mode} as the
+defaults for the results of decoding the file. The default defaults

-An alternative form of \var{decode} which stores the result in the

+This call decodes uuencoded file \var{in_file} placing the result on
