Installation
-------------------
 *  .	Put distribution kit (Zip-file) in the special directory for the 
	RADIUS, unpack & build executable image of the RADIUS server.

 *  .	Revise & edit RADIUS_STARTUP.COM & RADIUS_START.COM from distribution kit.

 *  .	Optionaly, add two entry in the SERVICES file, example for TCPWare-TCP 
	follows:
	...
	radius          1645/udp
	radact          1646/udp
	...

 *  .	Edit CLIENTS file from RADIUS distribution kit for adding IP names of your Network
	Access Servers and "shared secret" (don't forget that maximum length of 
	"shared secret" can't be more that 8 bytes.

 *  .	Start RADIUS server by RADIUS_STARTUP.COM as detached process, or for debuging
	purpose run RADIUS_START.COM from command line.

-------------------
Changes & Additions
-------------------
 *  .	This version is not allow of password changing by RADPASS or by something 
	like it facilities.


 *  .	Optimizations issue
	All critical file I/O  is rewritted with  RMS I/O, in particulary,
	access to USERS. file controled by discipline:
	USERS. file opening at start of server; during run of server USERS. file
	stay open; for each 10 minutes (0 00:10:00.00) this file is marked as 
	expired by setting of special flag; when a next request is arrived the
	file is reopened again and expiration flag is cleared.

	This discipline reduces overhead for opening of the file during 
	processing of each authentication request, and take advantages of 
	buffered I/O with big numbers of RMS buffers.

	All requestes to IP to NAME (reverse resolving) translation use caching.
