Change the INSTALL documentation for unified builds

Because of the unified scheme, building on different platforms is very
similar.  We currently have Unix and OpenVMS on the unified scheme,
which means that a separate INSTALL.VMS is no longer needed.

- Note on support for multiple builds
- -----------------------------------
-
- OpenSSL is usually built in its source tree.  Unfortunately, this doesn't
- support building for multiple platforms from the same source tree very well.
- It is however possible to build in a separate tree through the use of lots
- of symbolic links, which should be prepared like this:
-
-	mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
-	cd objtree/"`uname -s`-`uname -r`-`uname -m`"
-	(cd $OPENSSL_SOURCE; find . -type f) | while read F; do
-		mkdir -p `dirname $F`
-		rm -f $F; ln -s $OPENSSL_SOURCE/$F $F
-		echo $F '->' $OPENSSL_SOURCE/$F
-	done
-	make -f Makefile.in clean
-
- OPENSSL_SOURCE is an environment variable that contains the absolute (this
- is important!) path to the OpenSSL source tree.
-
- Also, operations like 'make update' should still be made in the source tree.

-   Cheking the distribution     - Mandatory reading.

-
- Requirements
- ------------
-
- To build and install OpenSSL, you will need:
-
-  * Perl 5 with core modules (please read README.PERL)
-  * The perl module Text::Template (please read README.PERL)
-  * DEC C or some other ANSI C compiler.  VAX C is *not* supported.
-    [Note: OpenSSL has only been tested with DEC C.  Compiling with 
-     a different ANSI C compiler may require some work]
-
- Checking the distribution
- -------------------------
-
- There have been reports of places where the distribution didn't quite
- get through, for example if you've copied the tree from a NFS-mounted
- Unix mount point.
-
- The easiest way to check if everything got through as it should is to
- check for one of the following files:
-
-  [.crypto]opensslconf^.h.in
-
- The best way to get a correct distribution is to download the gzipped
- tar file from ftp://ftp.openssl.org/source/, use GUNZIP to uncompress
- it and use VMSTAR to unpack the resulting tar file.
-
- GUNZIP is available {FIXME: where is it available?}
-
- VMSTAR is available {FIXME: where is it available?}
-
-
- Quick start
- -----------
-
- If you want to just get on with it, do this:
-
-  $ @config
-  $ mms
-  $ mms test
-  $ mmm install
-
- This will buidl and install OpenSSL in the default location, which is
- SYS$COMMON:[OPENSSL-'VERSION'].  If you want it to be anywhere else,
- run config.com like this:
-
-  $ @config --prefix=PROGRAM:[OPENSSL]

+ Requirement details
+ -------------------
+
+ In addition to the requirements listed in INSTALL, these are required
+ as well:
+
+  * At least ODS-5 disk organization for source and build.
+    Installation can be done on any existing disk organization.
+
+
+ About ANSI C compiler
+ ---------------------
+
+ An ANSI C compiled is needed among other things.  This means that VAX C
+ is not and will not be supported.
+
+ We have only tested with DEC C (a.k.a HP VMS C / VSI C), compiling with
+ a different ANSI C compiler may require some work.
+
+
+ Checking the distribution
+ -------------------------
+
+ There have been reports of places where the distribution didn't quite
+ get through, for example if you've copied the tree from a NFS-mounted
+ Unix mount point.
+
+ The easiest way to check if everything got through as it should is to
+ check for one of the following files:
+
+   [.crypto]opensslconf^.h.in
+
+ The best way to get a correct distribution is to download the gzipped
+ tar file from ftp://ftp.openssl.org/source/, use GZIP -d to uncompress
+ it and VMSTAR to unpack the resulting tar file.
+
+ Gzip and VMSTAR are available here:

+
+ Should you need it, you can find UnZip for VMS here:
