NAME
822header - print the header of a mail message

SYNOPSIS
822header

DESCRIPTION
822header reads an 822-format mail message from its standard input, and prints the header of the message. Under 822, the header is terminated by the end of the message or by a blank line. 822header also ends the header if it sees a line that cannot be part of a valid header field. Note that the UUCP-style From_ line placed before a message in an mbox file is not part of the message.
