libtelepathy-glib-unstable-dev 0.5.14-0ubuntu1 (i386 binary) in ubuntu gutsy

 This package contains development files, including a static library, for
 interfaces not yet considered sufficiently API- and ABI-stable to go in
 the libtelepathy-glib shared library.
 .
 This currently means the ContactInfo, Forwarding, Privacy and Renaming
 connection interfaces; the ContactSearch channel type; and the Hold and
 Transfer channel interfaces. As these interfaces become stable, they may
 be moved into the shared library.
 .
 Due to the unstable nature of this library, Debian packages which
 Build-Depend on this library should only be uploaded to experimental.
 .
 Telepathy is a D-Bus framework for unifying real time communication,
 including instant messaging, voice calls and video calls. It abstracts
 differences between protocols to provide a unified interface for
 applications.
