sakura is a terminal emulator based on GTK and libvte. It's a terminal emulator with few dependencies, so you don't need a full GNOME desktop installed to have a decent terminal emulator. There are several VTE-based terminal emulators like gnome-terminal, xfce-terminal, TermIt and probably some more published after sakura. sakura uses a gtk notebook to provide several tabbed terminals in one window and adds a contextual menu with several options. No more no less.
All the real and hard work is performed by libvte, a great library programmed by Behdad Esfahbod, Guilherme de S. Pastore and Nalin Dahyabhai.
sakura development is centralized in launchpad.
The repository is now in launchpad, so you can fill bugs reports and stuff in there. To get "bleeding edge" code from the bazaar repository, just type:
