+Installing Varnish on your computer
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+With open source software, you can choose to install binary
+packages or compile stuff from source-code. 
+
+In general, from a point of principle, I would argue that
+everybody should compile from source, but realistically
+binary packages are *so much easier* so lets cover that first:
+
+
+Installing Varnish from packages
+================================
+
+Installing Varnish on most relevant operating systems can usually 
+be done with with the systems package manager, typical examples
+being:
+
+FreeBSD (from source)
+	``cd /usr/ports/varnish && make install clean``
+FreeBSD (binary package)
+	``pkg_add -r varnish``
+
+If that worked for you, you can skip the rest of this document
+for now, and and start reading the much more interesting :ref:`Tutorial`
+instead.
+
+
+Compiling Varnish from source
+=============================
+
+If there are no binary packages available for your system, or if you
+want to compile Varnish from source for other reasons, follow these
+steps:
+
+First get a copy of the sourcecode using the ``svn`` command.  If
+you do not have this command, you need to install SubVersion_ on
+your system.  There is usually a binary package, try substituting
+"subversion" for "varnish" in the examples above, it might just work.
+
+To get the development source code::
+
+	svn co http://varnish-cache.org/svn/varnish/trunk
+
+or if you want the production branch::
+
+	svn co http://varnish-cache.org/svn/varnish/branches/2.1
+
+Next, configuration:  For this you will need ``libtoolize``, ``aclocal``,
+``autoheader``, ``automake`` and ``autoconf``, also known as *the
+autocrap tools* installed on your system.
+
+Once you have them::
+
+	cd varnish-cache
+	sh autogen.sh
+	sh configure
+	make
+
+The ``configure`` script takes some arguments, but more likely than
+not, you can forget about that for now, almost everything in Varnish
+are runtime parameters.
+
+Before you install, you may want to run the regression tests, make
+a cup of tea while it runs, it takes some minutes::
+
+	(cd bin/varnishtest && ./varnishtest tests/*.vtc)
+
+Don't worry of a single or two tests fail, some of the tests are a
+bit too timing sensitive (Please tell us which so we can fix it) but
+if a lot of them fails, and in particular if the ``b00000.vtc`` test 
+fails, something is horribly wrong, and you will get nowhere without
+figuring out what.
+
+And finally, the true test of a brave heart::
+
+	make install
+
+.. _SubVersion: http://subversion.tigris.org/
+
+
+Did you call them *autocrap* tools ?
+====================================
+
+Yes, in fact I did, because they are the worst possible non-solution
+to a self-inflicted problem.
+
+Back in the 1980'ies, the numerous mini- and micro-computer companies
+all jumped on the UNIX band-wagon, because it gave them an operating
+system for their hardware, but they also tried to "distinguish" themselves
+from the competitors, by "adding value".
+
+That "value" was incompatibility.
+
+You never knew where they put stuff, what arguments the compiler needed
+to behave sensibly, or for that matter, if there were a compiler to begin
+with.
+
+So some deranged imagination, came up with the idea of the ``configure``
+script, which sniffed at your system and set up a ``Makefile`` that would
+work.
+
+Writing configure scripts was hard work, for one thing you needed a ton
+of different systems to test them on, so copy&paste became the order of
+the day.
+
+Then some even more deranged imagination, came up with the idea of
+writing a script for writing configure scripts, and in an amazing
+and daring attempt at the "all time most deranged" crown, used an
+obscure and insufferable macro-processor called ``m4`` for the
+implementation.
+
+Now, as it transpires, writing the specification for the configure
+producing macros was tedious, so somebody wrote a tool to...
+
+...do you detect the pattern here ?
+
+Now, if the result of all this crap, was that I could write my source-code
+and tell a tool where the files were, and not only assume, but actually
+*trust* that things would just work out, then I could live with it.
+
+But as it transpires, that is not the case.  For one thing, all the
+autocrap tools add another layer of version-madness you need to get
+right before you can even think about compiling the source code.
+
+Second, it doesn't actually work, you still have to do the hard work
+and figure out the right way to explain to the autocrap tools what
+you are trying to do and how to do it, only you have to do so in 
+a language which is used to produce M4 macro invocations etc. etc.
+
+In the meantime, the UNIX diversity has shrunk from 50+ significantly
+different dialects to just a handful: Linux, \*BSD, Solaris and AIX
+and the autocrap tools have become part of the portability problem,
+rather than part of the solution.
+
+Amongst the silly activites of the autocrap generated configure script
+in Varnish are:
+
+* Looks for ANSI-C header files (show me a system later
+  than 1995 without them ?)
+
+* Existence and support for POSIX mandated symlinks, (which
+  are not used by Varnish btw.)
+
+* Tests, 19 different ways, that the compiler is not a relic from
+  SYS III days.  (Find me just one SYS III running computer with
+  an ethernet interface ?)
+
+* Checks if the ISO-C and POSIX mandated ``cos()`` function exists
+  in ``libm`` (No, I have no idea either...)
+
+&c. &c. &c.
+
+Some day when I have the time, I will rip out all the autocrap stuff
+and replace it with a 5 line shellscript that calls ``uname -s``.
