libgsf-gnome-1-dev 1.13.99-0ubuntu2 (amd64 binary) in ubuntu dapper

 This package contains the development files used in building applications
 that use the GNOME Structured File Library.
 .
 The GNOME Structured File Library 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.
