Benedikt Meurer Jannis Pohlmann Jeffs Franks Nick Schermer The tdb library, which is included with the Thunar distribution, was originally written as part of the Samba suite. My understanding is that the majority of the code was written by Andrew Trigell with the help of Paul "Rusty" Russell . Luke Kenneth Casson Leighton also contributed a few patches. Sorted freelist merge code added by Jeremy Allison . The stock_folder-copy and stock_folder-move icons where taken from gnome-icon-theme 2.18.0 whose authors are Lapo Calamandrei , Rodney Dawes , Luca Ferretti , Tuomas Kuosmanen , Andreas Nilsson and Jakub Steiner .
