 "  encoding type base64 is used:\n"
 "   mailsend -f user@example.com -smtp 10.100.30.1\n"
 "   -t user@example.com -sub \"this is a test\"\n"
 "   -attach \"file.pdf\" -attach \"file.jpg\"\n"

 "  By default, content disposition of all atachments are attachment, use\n"
 "  -disposition \"inline\" to give hint to the mail reader to display it as\n"
 "  mail body. Look at FAQ# 1 for details.\n"
 "\n"
 "  Including a body\n"
 "  ================\n"
 "  Only one file can be included as a body of the mail. If the\n"
 "  file is not us-ascii, the SMTP server has to support it. If you \n"
 "  include a binary file, result is undefined.\n"
 "\n"
 "   mailsend -f user@gmail -t user@example.com -smtp smtp.gamil.com\n"
 "    -port 587 -starttls -auth -user user@gmail.com -pass secret \n"
