 Radiusclient is a /bin/login replacement which gets called by a getty
 to log in a user and to setup the user's login environment. Normal
 login programs just check the login name and password which the user
 entered against the local password file (/etc/passwd, /etc/shadow).
 In contrast to that Radiusclient also uses the RADIUS protocol to
 authenticate the user.
 .
 This is the development package, to be able to develop programs that
 uses the RADIUS library.
