Subject: Add support for RADIUS accounting.  Note, this changes the format of
 the /etc/radius.conf file.   But the code contains hacks for backward
 compatibility, so old files will continue to work.

I updated the man pages and made a couple of minor changes, but
everything else was submitted by Oleg.

+In User Service (RADIUS).  RADIUS, defined in RFCs 2138 and 2139,
+allows clients to perform authentication and accounting by means of
+network requests to remote servers.
 .Sh INITIALIZATION
 To use the library, an application must first call
-.Fn rad_open
+.Fn rad_auth_open
+or
+.Fn rad_acct_open
 to obtain a
 .Va struct rad_handle * ,
 which provides the context for subsequent operations.
+The former function is used for RADIUS authentication and the
+latter is used for RADIUS accounting.
 Calls to
-.Fn rad_open
+.Fn rad_auth_open
+and
+.Fn rad_acct_open
 always succeed unless insufficient virtual memory is available.  If
-the necessary memory cannot be allocated,
-.Fn rad_open
-returns
+the necessary memory cannot be allocated, the functions return
 .Dv NULL .
+For compatibility with earlier versions of this library,
+.Fn rad_open
+is provided as a synonym for
+.Fn rad_auth_open .
