// The msg parameter should be an RFC 822-style email with headers

// first, a blank line, and then the message body. The lines of msg

// should be CRLF terminated. The msg headers should usually include
|

// fields such as "From", "To", "Subject", and "Cc". Sending "Bcc"

// messages is accomplished by including an email address in the to

// functionality. Higher-level packages exist outside of the standard

// library.
