@section Installation using ``Cygwin Setup''
The Cygwin Setup program is the @emph{only} recommended way to install
-Cygwin.
+Cygwin.
@subsection Why not install in C:\?
The Cygwin Setup program will prompt you for a "root" directory.
The default is @samp{C:\cygwin}, but you can change it. You are urged not to
-choose something like 'C:\' (the root directory on the system drive) for

your Cygwin root. If you do, then critical Cygwin system directories
-like 'etc', 'lib' and 'bin' could easily be corrupted by other (non-Cygwin)
-applications or packages that use \etc, \lib or \bin. Perhaps there is
-no conflict now, but who knows what you might install in the future?
-It's also just good common sense to segregate your Cygwin "filesystems"
-from the rest of your Windows system disk.

-@subsection Can I use Cygwin Setup to update a B18, B19, B20, B20.1 or CD-ROM (1.0) installation of Cygwin?
+@subsection Can I use Cygwin Setup to get old versions of packages (like gcc-2.95)?
-No, you must start from scratch with the new Cygwin Setup. The
-overall structure has changed so much that it would be pointless to
-try to accomodate old installations of Cygwin. You will probably be
-much better off with a whole new installation anyway. You may backup
-or rename your old installation first, or just install the new one
-somewhere else. Be sure to make note of your current mount table,
-because this will be overwritten during the new setup. Make sure you
-don't end up with two different versions of @samp{cygwin1.dll} on your
-system.
+Cygwin Setup can be used to install any packages that are on a
+Cygwin mirror, which usually includes one version previous to the
+current one. The complete list may be searched at
+@file{http://cygwin.com/packages/}. There is no complete archive of
+older packages. If you have a problem with the current version of
+a Cygwin package, please report it to the mailing list using the
+guidelines at @file{http://cygwin.com/problems.html}.
-Once you've installed the latest net release, Cygwin Setup will update
-just the individual packages that need it.
+That said, if you really need an older package, you may be able to find
+an outdated or archival mirror by searching the web for an old package
+version (for example, @samp{gcc2-2.95.3-10-src.tar.bz2}), but keep in
+mind that this older version will not be supported by the mailing list
+and that installing the older version will not help improve Cygwin.
@subsection Is Cygwin Setup, or one of the packages, infected with a virus?
NO. Cygwin Setup cannot do this for you. Use a tool designed for
this purpose. See @file{http://rsync.samba.org/},
-@file{http://sunsite.org.uk/packages/mirror/},
@file{http://wget.sunsite.dk/} for utilities that can do this for you.

+the Cygwin Setup homepage at
