glade 3.11.0-1 (amd64 binary) in ubuntu precise

 Glade is a RAD tool to enable quick and easy development of user
 interfaces for the GTK+ toolkit.
 .
 The user interfaces designed in Glade are stored in the well-known
 XML format, enabling easy integration with external tools. You will
 probably want to use it with tools such as libglade, which can load
 the XML files and create the interfaces at runtime.
 .
 This version is more modular than previous ones, so you can install
 modules to add additional widgets for Glade to use.
