Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

<title>Description</title>
|
|
|
|
<para><function>sd_journal_get_catalog()</function> retrieves a
|
|
message catalog entry for the current journal entry. This will
|
|
look up an entry in the message catalog by using the
|
|
<literal>MESSAGE_ID=</literal> field of the current journal entry.
|
|
Before returning the entry all journal field names in the catalog
|
|
entry text enclosed in "@" will be replaced by the respective
|
|
field values of the current entry. If a field name referenced in
|
|
the message catalog entry does not exist, in the current journal
|
|
entry, the "@" will be removed, but the field name otherwise left
|
|
untouched.</para>
|
|
|
|
<para><function>sd_journal_get_catalog_for_message_id()</function>
|
|
works similar to <function>sd_journal_get_catalog()</function> but
|
|
the entry is looked up by the specified message ID (no open
|
|
journal context is necessary for this), and no field substitution
|
|
is performed.</para>
|
|
|

|
|
|
<para><function>sd_journal_get_catalog()</function> and
|
|
<function>sd_journal_get_catalog_for_message_id()</function>
|
|
return 0 on success or a negative errno-style error code. If no
|
|
matching message catalog entry is found, -ENOENT is
|
|
returned.</para>
|
|
|
|
<para>On successful return, <parameter>ret</parameter> points to a

new string, which must be freed with
