.SH DESCRIPTION
.PP
The \fB\fC822fields\fR program reads an 822\-format email message from standard input.
For each input header \fB\fC_field_\fR, \fB\fC822fields\fR prints one line containing the
value of the field to standard output. If no \fB\fC_field_\fR appears, \fB\fC822fields\fR
looks for \fB\fC_subject_\fR\&.
.PP
The end of the message or the first line that cannot be part of an 822\-format
header field terminates the message message body.
.SH EXIT STATUS
.PP
If it encounters an error while processing a message, \fB\fC822fields\fR exits 111.
If \fB\fC822fields\fR finds any matching headers, it exits 0\&. Otherwise, \fB\fC822fields\fR
exits 100.
