	<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>The original Samba man pages were written by Karl Auer. 
	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. The conversion to DocBook XML 4.2 for
	Samba 3.0 was done by Alexander Bokovoy.</para>
