The software consists of SANE scanner drivers, "scanimage," and the
"saned" daemon.

A SANE scanner driver is used via a SANE front-end. This package
contains the command line front-end "scanimage". There are various
graphical front-ends like "xscanimage" (package sane-frontends), XSane
(package xsane), and the KDE front-end Kooka (package
kdegraphics3-scan).

The "saned" daemon provides the service "sane-port" to access scanners
that are connected to a server via network from client hosts that run
the "net" meta driver.
