     "@command{gnome-keyring} is a program that keeps passwords and other
secrets for users.  It is run as a daemon in the session, similar to
@command{ssh-agent}, and other applications locate it via an environment
variable or D-Bus.

The program can manage several keyrings, each with its own master password,
and there is also a session keyring which is never stored to disk, but
forgotten when the session ends.")

     "Tracker is a search engine and triplestore for desktop, embedded and mobile.

It is a middleware component aimed at desktop application developers who want
their apps to browse and search user content.  It's not designed to be used
directly by desktop users, but it provides a commandline tool named
@command{tracker} for the adventurous.

Tracker allows your application to instantly perform full-text searches across
all documents.  This feature is used by the @{emph{search} bar in GNOME Files, for
example.  This is achieved by indexing the user's home directory in the
background.

Tracker also allows your application to query and list content that the user
has stored.  For example, GNOME Music displays all the music files that are
found by Tracker.  This means that GNOME Music doesn't need to maintain a
database of its own.

If you need to go beyond simple searches, Tracker is also a linked data
endpoint and it understands SPARQL.")
