sakura is a terminal emulator based on GTK and libvte. It has few dependencies, so there's no need of a full GNOME desktop installed to have a powerful terminal emulator. sakura uses a gtk notebook to provide tabbed terminals in one window and has a contextual menu for configuration; it was designed without a menu bar. 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. There are several VTE-based terminal emulators like gnome-terminal, xfce-terminal, TermIt and several others published after sakura first release
sakura development is centralized in launchpad. The source repository, packages, bugs and translations are managed there.
To get "bleeding edge" code from the bazaar repository, just type:
bzr branch http://bazaar.launchpad.net/~dabisu/sakura/sakura
or in case you have a launchpad account and have uploaded your ssh key:
bzr branch lp:sakura
