+	  The Glasgow Haskell Compiler -- version 2.02
+	  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We are pleased to announce the first release of the Glasgow Haskell
+Compiler (GHC, version 2.02) for *Haskell 1.4*.  Sources and binaries
+are freely available by anonymous FTP and on the World-Wide Web;
+details below.
+
+Haskell is "the" standard lazy functional programming language; the
+current language version is 1.3, agreed in May, 1996.  The Haskell
+Report is online at
+
+	http://haskell.cs.yale.edu/1.4/haskell-report.html
+
+GHC 2.02 is a beta-quality release - some highlights:
+
+  * It is reliable.
+     It has been extensively tested against a large suite of Haskell 1.2 
+     programs, but not so extensively tested against Haskell 1.4 programs 
+     because we don't have a comprehensive set (Donations of Haskell 1.4
+     programs to our test suite are most welcome).
+
+  * It should generate good code.
+     All the optimisations that GHC 0.29 used to do are back in, with 
+     the exception of specialisation.  It ought to be the case that
+     GHC 2.02 outperforms GHC 0.29, because it has a much better
+     handle on cross-module inlining, but there's a good chance that
+     there are performance "holes" lurking.  We have yet to make
+     a systematic comparison.  (Please send us programs where 2.02
+     does noticeably worse than 0.29.)
+
+  * It is more expensive than it should be.
+     GHC 2.02 has received even less attention to its own performance.
+     At present it eats more space and time than GHC 0.29, especially
+     for very small programs.  We're working on this.
+
+  * A couple of Haskell 1.4 features are incompletely supported,
+    notably polymorphic strictness annotations, and Unicode.
+
+If you want to use Haskell 1.4, this is a good moment to switch.  If
+you don't need the Haskell 1.4 extensions, then stay with GHC 0.29.
+If you want to hack on GHC itself, then 2.02 is definitely for you.
+The release notes comment further on this point.
+
+GHC 2.02 is substantially changed from 2.01.  Changes worth noting
+include:
+
+  * The whole front end, which deals with the module system, has 
+    been rewritten. The interface file format has changed.
+
+  * GHC 2.02 comes complete with Green Card, a C foreign language 
+    interface for GHC.  Green card is a pre-processor that
+    scans Haskell source files for Green Card directives, which
+    it expands into tons of "ccall" boilerplate that marshalls
+    your arguments to and from C.
+
+  * GHC 2.02 is available for Win32 platforms.  From now on, Win32
+    (Windows NT and Windows 95) will be a fully supported platform
+    for GHC.
+
+  * GHC 2.02 supports full cross module inlining.  Unlike 0.29 and
+    its predecessors, inlining can happen even if the inlined body
+    mentions a function or type that is not itself exported.  This is
+    one place Haskell 1.4's new module system really pays off.
+
+  * Like 2.01, GHC 2.02 aborts a compilation if it decides that
+    nothing that the module imports *and acually uses* has changed.
+    This decision is now taken by the compiler itself, rather than
+    by a Perl script (as in 2.01) which sometimes got it wrong.
+
+  * The ghc/lib libraries are much more systematically organised.
+
+  * There's a completely new "make" system.  This will mainly affect people
+    who want the source distribution, who will hopefully find it much, much,
+    easier than grappling with the old Jmakefiles.  Even for binary
+    installation, the procedure is a little simpler, though.
+
+Please see the release notes for a complete discussion of What's New.
+
+To run this release, you need a machine with 16+MB memory (more if
+building from sources), GNU C (`gcc'), and `perl'.  We have seen GHC
+2.01 work on these platforms: alpha-dec-osf2, hppa1.1-hp-hpux9,
+sparc-sun-{sunos4,solaris2}, mips-sgi-irix5, and
+i386-unknown-{linux,solaris2,freebsd,cygwin32}.  Similar platforms
+should work with minimal hacking effort.  The installer's guide give a
+complete run-down of what-ports-work.
+
+Binaries are distributed in `bundles', e.g. a "profiling bundle" or a
+"concurrency bundle" for your platform.  Just grab the ones you need.
+
+Once you have the distribution, please follow the pointers in the
+README file to find all of the documentation about this release.  NB:
+preserve modification times when un-tarring the files (no `m' option
+for tar, please)!
+
+We run mailing lists for GHC users and bug reports; to subscribe, send
+mail to majordomo@dcs.gla.ac.uk; the msg body should be:
+
+    subscribe glasgow-haskell-<which> Your Name <your-email@where.you.are>
+
+Please send bug reports about GHC to glasgow-haskell-bugs@dcs.gla.ac.uk.

+======================================================================
+How to get GHC 2.02:
+
+This release is available by anonymous FTP from the main Haskell
+archive sites, in the directory pub/haskell/glasgow:
+
+	ftp.dcs.gla.ac.uk   (130.209.240.50)
+	ftp.cs.chalmers.se  (129.16.227.140)
+	haskell.cs.yale.edu (128.36.11.43)
+
+The Glasgow site is mirrored by src.doc.ic.ac.uk (146.169.43.1), in
+computing/programming/languages/haskell/glasgow.
+
+These are the available files (.gz files are gzipped) -- some are `on
+demand', ask if you don't see them:
+
+README.html             A WWW `front-end' to the contents of the glasgow
+			directory.
+
+ghc-2.02-src.tar.gz	The source distribution; about 3MB.

+			case your TeX setup doesn't agree with our
+			DVI files...
+
+ghc-2.02-<platform>.tar.gz Basic binary distribution for a particular
+			<platform>.  Unpack and go: you can compile
+			and run Haskell programs with nothing but one
+			of these files.  NB: does *not* include
+			profiling (see below).

+
+ghc-2.02-hc-files.tar.gz Basic set of intermediate C (.hc) files for the

+			 world'.  Used for bootstrapping the system.
+			 About 4MB.
+
+ghc-2.02-<bundle>-hc-files.tar.gz Further sets of .hc files, for

+
+ghc-2.02-hi-files-<blah>.tar.gz Sometimes it's more convenient to
+			use a different set of interface files than
+			the ones in *-src.tar.gz.  (The installation
+			guide will advise you of this.)
