"quopri" --- Encode and decode MIME quoted-printable data
*********************************************************

**Source code:** Lib/quopri.py

======================================================================

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 "base64"
module is more compact if there are many such characters, as when
sending a graphics file.

quopri.decode(input, output, header=False)

   Decode the contents of the *input* file and write the resulting
   decoded binary data to the *output* file. *input* and *output* must
   be *binary file objects*.  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".

quopri.encode(input, output, quotetabs, header=False)

   Encode the contents of the *input* file and write the resulting
   quoted- printable data to the *output* file. *input* and *output*
   must be *binary file objects*. *quotetabs*, a flag which controls
   whether to encode embedded spaces and tabs must be provideda and
   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**.  *header* is
   a flag which controls if spaces are encoded as underscores as per
   **RFC 1522**.

quopri.decodestring(s, header=False)

   Like "decode()", except that it accepts a source "bytes" and
   returns the corresponding decoded "bytes".

quopri.encodestring(s, quotetabs=False, header=False)

   Like "encode()", except that it accepts a source "bytes" and
   returns the corresponding encoded "bytes". By default, it sends a
   False value to *quotetabs* parameter of the "encode()" function.
