qp
==

   This library deals with decoding and encoding Quoted-Printable text.

   Very briefly explained, QP encoding means translating all 8-bit
characters (and lots of control characters) into things that look like
`=EF'; that is, an equal sign followed by the byte encoded as a hex
string.  It is defined in RFC 2045.

   The following functions are defined by the library:

 - Command: quoted-printable-decode-region FROM TO &optional
          CODING-SYSTEM
     QP-decode all the encoded text in the region.  If CODING-SYSTEM is
     non-nil, decode bytes into characters with that coding-system.  It
     is probably better not to use CODING-SYSTEM; instead decode into a
     unibyte buffer, decode that appropriately and then interpret it as
     multibyte.

 - Function: quoted-printable-decode-string STRING &optional
          CODING-SYSTEM
     Return a QP-encoded copy of STRING.  If CODING-SYSTEM is non-nil,
     decode bytes into characters with that coding-system.

 - Command: quoted-printable-encode-region FROM TO &optional FOLD CLASS
     QP-encode all the region.  If FOLD is non-NIL, fold lines at 76
     characters, as required by the RFC.  If CLASS is non-`nil',
     translate the characters not matched by that regexp class, which
     should be in the form expected by SKIP-CHARS-FORWARD and should
     probably not contain literal eight-bit characters.  Specifying
     CLASS makes sense to do extra encoding in header fields.

     If variable MM-USE-ULTRA-SAFE-ENCODING is defined and non-`nil',
     fold lines unconditionally and encode `From ' and `-' at the start
     of lines..

 - Function: quoted-printable-encode-string string
     Return a QP-encoded copy of STRING.
