	<title>ENVIRONMENT VARIABLES</title>

	<para>The <parameter>$TAPE</parameter> variable specifies the 
	default tape device to write to. May be overridden
	with the -t option. </para>
</refsect1>


<refsect1>
	<title>BUGS</title>

	<para>The <command>smbtar</command> script has different 
	options from ordinary tar and tar called from smbclient. </para>

</refsect1>

<refsect1>
	<title>CAVEATS</title>

	<para>Sites that are more careful about security may not like 
	the way the script handles PC passwords. Backup and restore work 
	on entire shares, should work on file lists. smbtar works best
	with GNU tar and may not work well with other versions. </para>

	<title>AUTHOR</title>
	
	<para>The original Samba software and related utilities 
	were created by Andrew Tridgell. Samba is now developed
	by the Samba Team as an Open Source project similar 
	to the way the Linux kernel is developed.</para>
	
	<para><ulink url="mailto:poultenr@logica.co.uk">Ricky Poulten</ulink>  
	wrote the tar extension and this man page. The <command>smbtar</command> 
	script was heavily rewritten and improved by <ulink 
	url="mailto:Martin.Kraemer@mch.sni.de">Martin Kraemer</ulink>. Many 
	thanks to everyone who suggested extensions, improvements, bug 
	fixes, etc. The man page sources were converted to YODL format (another 
	excellent piece of Open Source software, available at
	<ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
	ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0 
	release by Jeremy Allison.  The conversion to DocBook for 
	Samba 2.2 was done by Gerald Carter.</para>
