INSTALLATION

   1. edit Netrek.tmpl adding the appropriate paths for the MP libraries,
      and setting or resetting OPTIONS.  If you don't have it, the GNU 
      mp library is available on prep.ai.mit.edu.  Look for 
      /pub/[GNU,gnu]/gmp*  Version 1.20 and beyond require the GMP library
      when using RSA encryption.
      
   2. get rsa_clientutil.c and mkkey.c from the RSA distribution.
      distribution can be found at: ftp.ecst.csuchico.edu as 
      /pub/netrek/src/rsa-client.tar.gz.crypt.  Then you will have to email 
      server@ecst.csuchico.edu and tell them that you are a Canadian or US 
      citizen so they can give you the crypt key. 

      U.S. export restrictions have been placed upon certain classes
      of encryption technology including RSA and DES.  Software 
      implementing these techniques cannot be exported outside the U.S.,
      anyone doing so could face prosecution.

   3. If you have an rsa key already, set Netrek.tmpl's RSA_KEYFILE for your  
      machines architecture to its name (it should have a .secret extension 
      already).  If you do not have one, read on.
      
   4. xmkmf

   5. If you're compiling under Ultrix with the native C compiler that supports
      optimization -O4, skip this step and see DEC/ULTRIX-SPECIFIC INSTALL.

      Otherwise, do:
	 make depend all

  (6. If the depend step fails because you don't have a key you can
      make one with mkkey.  Do ./mkkey for instructions.)

DEC/ULTRIX-SPECIFIC INSTALL
   
   The dec native C compiler supports optimization -O4 which can't be
   used with the -c flag.  This means all source files must be compiled 
   together in one step if you want to use it.

   After step 4, above, make sure CDEBUGFLAGS in Netrek.tmpl is empty and do:
	 make randomize mkkey rsa-client.c
   then do
	 make CDEBUGFLAGS=-O4 netrek.dec

CLIENT DETAILS
