+=======================================
+Wanton destruction for the greater good
+=======================================
+
+We live in an old house, and it's all wrong for us.
+
+When I bought this house, it was perfect, or at least perfect enough.
+
+But times have changed.
+
+I have no small kids anymore, and rather than just right for two
+kids to tumble in, the garden is now too small for all the flowers
+we want.
+
+And the rooms are not where we want them, there are too many stairs
+in all the wrong places, and the kitchen needs to be torn out and
+a new built.
+
+I'm sure that some other family will be able to fall in love with
+this house, the way we did, but there is no realistic way to
+rebuild it, to become the house we want now.
+
+For one thing, doing major surgery on a house while you live in it
+is double-minus-fun and it always slows the rebuild project down
+when you have to keep at least one toilet working and sanitary and
+be able to cook and sleep on the building site.
+
+So we'll be building a new house on a plot of land on the other
+side of the road, one of the coming years, a house which is right
+for us, and then we will sell this old house, to a family with small
+children, who will love it, and rip out the old funky kitchen and
+make a new one before they move in.
+
+One would think that software would be nothing like an old house,
+but they are more alike than most people imagine.
+
+Using a major piece of software, is like moving into a house: You
+need to adapt your life and the house or the software to each other,
+since nothing is ever quite perfect, there will be limitations.
+
+And those limitations affect how you think: If you live in a
+2 bedroom apartment, you won't even be considering inviting 80
+guests to a party.
+
+A lot of Varnish-users have taken time to figure out how Varnish
+fits into their lives and made the compromises necessary to make
+it work, and once you've done that, you moved on to other problems,
+but the limitations of Varnish keeps affecting how you think about
+your website, even if you don't realize this.
+
+Well, I've got news for you: You'll be moving into a new house in
+the next couple of years, it'll be called Varnish V4 and that means
+that you will have to decide who gets which room and where to store
+the towels and grandmothers old china, all over again.
+
+I'm sure you'll hate me for it, "Why do we have to move ?", "It
+really wasn't that bad after all" and so on and so forth.
+But if I do my job right, that will soon turn into "Ohh, that's
+pretty neat, I always wanted one of those..." and "Hey... Watch me
+do THIS!" etc.
+
+I could have started with a fresh GIT repository, to make it clear
+that what is happening right now is the construction of an entirely
+new house, but software isn't built from physical objects, so I
+don't need to do that: You can keep using Varnish, while I rebuild
+it, and thanks to the wonder of bits, you won't see a trace of
+dirt or dust while it happens.
+
+So don't be alarmed by the wanton destruction you will see in -trunk
+the coming weeks, it is not destroying the Varnish you are using
+for your website today, it is building the new one you will be using
+in the future.
+
+And it's going to be perfect for you, at least for some years...
