Libglade is a small library that allows a program to load its user
interface from am XML description at runtime. Libglade uses the XML
file format used by the GLADE user interface builder GLADE, so
libglade acts as an alternative to GLADE's code generation
approach. Libglade also provides a simple interface for connecting
handlers to the various signals in the interface (on platforms where
the gmodule library works correctly, it is possible to connect all the
handlers with a single function call). Once the interface has been
instantiated, libglade gives no overhead, so other than the short
initial interface loading time, there is no performance tradeoff.
