-"""Mimification and unmimification of mail messages.\r
-\r
-Decode quoted-printable parts of a mail message or encode using\r
-quoted-printable.\r
-\r
-Usage:\r
- mimify(input, output)\r
- unmimify(input, output, decode_base64 = 0)\r
-to encode and decode respectively. Input and output may be the name\r
-of a file or an open file object. Only a readline() method is used\r
-on the input file, only a write() method is used on the output file.\r
-When using file names, the input and output file names may be the\r
-same.\r
-\r
-Interactive usage:\r
- mimify.py -e [infile [outfile]]\r
- mimify.py -d [infile [outfile]]\r
-to encode and decode respectively. Infile defaults to standard\r
-input and outfile to standard output.\r
