GdkRgb is a rewrite of the image rendering subsystem of Gtk+. Advantages over plain Gtk+ 1.0.x include higher speed, very smooth and pretty dithered modes, and support for more displays and visuals. It is currently checked into development versions of Gtk+ (and used in the development tree of the Gimp), but is also packaged separately for application authors who want to maintain Gtk 1.0.x compatibility. The programming interface is quite simple.
gbrctl is a GNOME utility to configure the Linux Ethernet Bridging code as found in Linux kernels version 2.3.47 and higher, and patched 2.2.x kernels. It features fast and easy bridge and port editing and a stack window, displaying images of your active bridges with 'LEDs' displaying the current port statuses.
Frood is a Gtk/Perl LDAP client designed to work on LDAPv2 and LDAPv3 servers. You can extract data from a server by either searching (either by baseDN, scope, filter, attribute names, or attributes) or by browsing a hierarchial tree structure. Entries can be added, deleted, modified, or have their RDNs modified. LDIF files can be imported and exported. LDAPv3 schema can be edited.
