zeitgeist-core binary package in Ubuntu Oracular amd64

 Zeitgeist is a service which logs the user's activities and events
 (files opened, websites visited,
 conversations held with other people, etc.)
 and makes the relevant information available to other applications.
 .
 It serves as a comprehensive activity log
 and also makes it possible to determine relationships
 between items based on usage patterns.
 .
 This package contains the main daemon
 (in its new Vala implementation, codenamed "Bluebird").
 It also includes the FTS (Full Text Search) extension.
