.SH NAME
ezmlm-idx \- create index for mailing list archive
.SH SYNOPSIS
.B ezmlm-idx
[
.B \-dDF

.B \-f\I msg

.I dir
.SH DESCRIPTION
.B ezmlm-idx
reads all archived messages for the list in
.I dir
from
.IR dir\fB/archive/
and creates a message index. The index file format is identical to
that produced by
.B ezmlm-send(1)
(when
.IR dir\fB/indexed
is present).

.B ezmlm-idx
will ignore messages that do not have the owner execute bit set.

.B ezmlm-idx
will create the the index file under a different name and then
move it into place.

If 
.IR dir\fB/indexed
does not exist,
.B ezmlm-idx
will create it to enable the use of the newly created subject and author index.

.B ezmlm-idx
will remove reply-indicators and the prefix from the subject before
entry into the index, as described for
.BR ezmlm-send(1) .
.B ezmlm-idx
will decode rfc2047 encoded subject and author headers. When unfolding
split lines,
.B ezmlm-idx
will remove redundant escape sequences for the character
set specified in
.IR dir\fB/charset .

.B ezmlm-idx
calculates a subject hash based on the normalized subject header. Normalization
removes linear whitespace, case information, and message reply indicators.
The subject hash is used by
.B ezmlm-get(1)
for message threading.
.SH OPTIONS
.TP
.B \-d
Use the ``Date:'' header for date information, rather than the top ``Received:''
header. This is unreliable, but useful when messages have been transferred from
another type of archive by mailing them to ezmlm.
.B ezmlm-idx
converts dates with two-digit years ``xx'' to 19xx if xx is >= 70. Otherwise,
20xx is assumed.
.TP
.B \-D
(Default.)
Use the ``Received:'' header, not the ``Date:'' header. This is more reliable
since this is the header added by the receiving qmail. Also, this results
in always correctly formatted dates in the same time zone (usually UTC).
.TP
.B \-f\fI msg
Start indexing with the archive section containing message
.IR msg .
This is useful if you have removed part of the archive and do not want to
create (empty) directories and index files for these. It also decreases
.B ezmlm-idx
memory use.
.TP
.B \-F
(Default.)
Start indexing from message 1.
