<title>DESCRIPTION</title>
<para>
ltdbtool is a utility to manipulate CTDB's local TDB databases
(LTDBs) without connecting to a CTDB daemon.
</para>

<para>
convert between an LTDB and a non-clustered tdb
by adding or removing CTDB headers and
</para>
</listitem>
<listitem>
<para>convert between 64 and 32 bit LTDBs where the CTDB record
headers differ by 4 bytes of padding.
