-The libtool program, available from your favourite GNU software
-archive, is required to compile these programs.
+ recycle
+ A recycle-bin like modules. When used any unlink call
+ will be intercepted and files moved to the recycle
+ directory nstead of beeing deleted.
+
+ block
+ A simple module to block access to certain mount points or
+ directories. This module only hides the specified directories
+ and all directories beneath them. It should NOT be used to
+ secure directories. If the name of a file in one of those
+ directories is known, the file can still be opened.
+
+ netatalk
+ A netatalk module, that will ease co-existence of samba and
+ netatalk file sharing services.
+ Looka t the README for more informations.
+
+You may have problems to compile these modules, as shared libraries are
+compiled and linked in different ways on different systems.
+I currently tested them against GNU/linux and IRIX.
To use the VFS modules, create a share similar to the one below. The
important parameter is the 'vfs object' parameter which must point to
