This package contains the development files used in building applications that use the GNOME Structured File Library. . The GNOME Structured File Library aims to provide an efficient extensible I/O abstraction for dealing with different structured file formats. It is actively being developed and its API is still likely to undergo significant changes (in particular, extensions). . This package supports the use of Bonobo, GNOME's CORBA-based component architecture and of GNOME-VFS, the GNOME virtual file-system.
