+Hello Marek,
+
+I have created a diffile against the 980403 release that adds
+functionality to newusers for automatic handling of users with only
+anonymous ftp login (using the guestgroup feature in ftpaccess, which
+means that the users home directory looks like '/home/user/./'). It also
+adds a commandline argument to specify an initial directory structure
+for such users, with a tarball normally containing the bin,lib,etc
+directories used in the chrooted environment.
+
+I am using it to automatically create chunks of users with only ftp
+access for a webserver.
+
+I have tried to follow your coding standards and I believe it is bug
+free but.. well, who knows. :) It's not much code however.
+
+I hope you find it useful. Do what you like with it, feel free to ask if
+anything is unclear.
+
+Best rgds,
+  Calle Karlsson
