281 <title>AUTHOR</title>
283 <para>The original Samba software and related utilities
284 were created by Andrew Tridgell. Samba is now developed
285 by the Samba Team as an Open Source project similar
286 to the way the Linux kernel is developed.</para>
288 <para>The original Samba man pages were written by Karl Auer.
289 The man page sources were converted to YODL format (another
290 excellent piece of Open Source software, available at <ulink url="ftp://ftp.icce.rug.nl/pub/unix/">
291 ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
292 release by Jeremy Allison. The conversion to DocBook for
293 Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
294 Samba 3.0 was done by Alexander Bokovoy.</para>
