History" below for a description of the changes.

How to Get the High Performance Fortran Language Specification
==============================================================

There are three ways to get a copy of the draft:

	1. Anonymous FTP: The most recent draft is available on 
	   titan.cs.rice.edu in the directory public/HPFF/draft.
	   Several files are kept there, including compressed
	   Postscript files of previous versions of the draft.  The
	   most current version of this draft is 0.4, which can be
	   retrieved as a tar file containing LaTeX source
	   (hpf-v04.tar) or in Postscript format (hpf-v04.ps);
	   both of these are also available as compressed files.
	   Several other sites also have the draft available in one or
           more formats, including think.com, ftp.gmd.de,
	   theory.tc.cornell.edu, and minerva.npac.syr.edu.

	2. Electronic mail: The most recent draft is available from
	   the Softlib server at Rice University.  This can be
	   accessed in two ways:
	     A. Send electronic mail to softlib@cs.rice.edu with "send 
		hpf-v04.ps" in the message body. The report is sent as a 
		Postscript file.
	     B. Send electronic mail to softlib@cs.rice.edu with "send 
		hpf-v04.tar.Z" in the message body. The report is
		sent as a uuencodeded compressed tar file containing
		LaTeX source.
             C. Send electronic mail to netlib@ornl.gov with "send
                hpf-v04.ps from hpf" in the message body.  The report
                is sent as a Postscript file.  This site also has the
                LaTeX source of the draft; use "send index from hpf"
                to see the file names.
             D. Send electronic mail to netlib@research.att.com with
	        "send hpf-v04.ps from hpff" in the message body.  The
		report is sent as a Postscript file.
	   (In all cases, the reply is sent as several messages to
	   avoid mailer restrictions; edit the message bodies together
	   to obtain the whole file.)  The same files can be obtained
	   from David Loveman (loveman@mpsg.enet.dec.com) and Chuck
	   Koelbel (chk@cs.rice.edu), but replies will take longer
	   because real people have to answer the mail.

	3. Hardcopy: The most recent draft is available as technical report 
	   CRPC-TR 92225 from the Center for Research on Parallel
	   Computation at Rice University.  Send requests to
		Theresa Chapman
		CITI/CRPC, Box 1892
		Rice University
		Houston, TX 77251
	   There is a charge of $50.00 for this report to cover copying and 
	   mailing costs.

A few caveats about the HPF draft:

	A. The current version contains some material that is still
	   under active discussion.  Changes will be fairly frequent
	   until at least December 1992.  New versions will be
           announced on the HPFF mailing list and in the newsgroups
	   comp.parallel, comp.lang.misc, and comp.lang.fortran.

	B. The HPF Language Specification does not necessarily
	   represent the official view of any individual, company,
	   university, government, or other agency.

	C. Please address any questions, comments, or possible
	   inconsistencies in the draft to hpff-comments@cs.rice.edu.
