Martin Kraemer\&. 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
|
|
ftp://ftp\&.icce\&.rug\&.nl/pub/unix/) 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\&.
