+:mod:`quopri` --- Encode and decode MIME quoted-printable data
+==============================================================
+
+.. module:: quopri
+   :synopsis: Encode and decode files using the MIME quoted-printable encoding.
+
+
+.. index::
+   pair: quoted-printable; encoding
+   single: MIME; quoted-printable encoding
+
+This module performs quoted-printable transport encoding and decoding, as
+defined in :rfc:`1521`: "MIME (Multipurpose Internet Mail Extensions) Part One:
+Mechanisms for Specifying and Describing the Format of Internet Message Bodies".
+The quoted-printable encoding is designed for data where there are relatively
+few nonprintable characters; the base64 encoding scheme available via the
+:mod:`base64` module is more compact if there are many such characters, as when
+sending a graphics file.
+
+
+.. function:: decode(input, output[,header])
+
+   Decode the contents of the *input* file and write the resulting decoded binary
+   data to the *output* file. *input* and *output* must either be file objects or
+   objects that mimic the file object interface. *input* will be read until
+   ``input.readline()`` returns an empty string. If the optional argument *header*
+   is present and true, underscore will be decoded as space. This is used to decode
+   "Q"-encoded headers as described in :rfc:`1522`: "MIME (Multipurpose Internet
+   Mail Extensions) Part Two: Message Header Extensions for Non-ASCII Text".
+
+
+.. function:: encode(input, output, quotetabs)
+
+   Encode the contents of the *input* file and write the resulting quoted-printable
+   data to the *output* file. *input* and *output* must either be file objects or
+   objects that mimic the file object interface. *input* will be read until
+   ``input.readline()`` returns an empty string. *quotetabs* is a flag which
+   controls whether to encode embedded spaces and tabs; when true it encodes such
+   embedded whitespace, and when false it leaves them unencoded.  Note that spaces
+   and tabs appearing at the end of lines are always encoded, as per :rfc:`1521`.
+
+
+.. function:: decodestring(s[,header])
+
+   Like :func:`decode`, except that it accepts a source string and returns the
+   corresponding decoded string.
+
+
+.. function:: encodestring(s[, quotetabs])
+
+   Like :func:`encode`, except that it accepts a source string and returns the
+   corresponding encoded string.  *quotetabs* is optional (defaulting to 0), and is
+   passed straight through to :func:`encode`.
