-----------------

1. Unlike standardized compilers in the Unix world, different flags
   and libs are used for WIN32.  Currently we distinguish between
   Borland 5.0 or VC++ 4.0 or higher.  Thus, a dependency file in
   $(PVM_ROOT)/conf named WIN32.def can be modified to point to the
   installed Compiler.  It also provides a compiler detection mechanism,
   which works with a normal compiler installation (checking for
   INCLUDE environment variables).

2. Make sure you set PVM_ROOT, PVM_ARCH, PVM_TMP, PVM_RSH before using
   PVM.  Differences in setting these variables are for NT or WIN95.
   In NT the Admin has to put these variables into the system variables
   (Control Panel -> System -> Environment variables).

   Installing requires only pointing to the location of this extracted
   directory.  No registry modifications need to be performed.
   Also, it is now possible to put the pvmd.exe file into the
   autostart group for automatic startup.  The way to build a
   Virtual Machine is briefly described in Section 3.

3. PVM is built by invoking the console command "pvm" with an additional
   hostfile argument which identifies potential resources.  The machine
   on which "pvm" is run for the first time (in a given session) is
   referred to as the "master daemon."  If this machine crashes, your
   PVM virtual machine goes down (a single point of failure).

   Manual adding of hosts is performed by the "add" command in the
   "pvm" console.  Add commands must specify the location of the daemon,
   e.g.
		pvm> add "hostname dx=d:\pvm3\lib\pvmd"

4. Rshd or rexecd are required for WINNT, Rshd for WIN95.  This is
   additional (shareware) software that you will find on the WWW,
   as long as MS does not offer its own solution.
   Please note that the rshd is required to run remote processes
   under your account.  If you find pvm{d,l}.System in your PVM_TMP
   directory, then the rshd is NOT working properly.

5. If you are new to PVM, please read the book on PVM or check out the
   user's guide.  You will find it on the PVM homepage at:

        http://www.epm.ornl.gov/pvm

6. Before using PVM, you should test the functionality of the additional
   software, e.g.

		"rsh remotehost -l login dir | more"

   This should show the directory listing of the remote host.  Piping
   to "more" additionally checks for buffered std{io,err}.
