+%description
+This is an implementation of particular kind of B-tree, based on
+research by Ohad Rodeh. See "B-trees, Shadowing, and Clones" (copied
+here with permission of author) for details on the data
+structure. This is the same data structure that btrfs uses. Note that
+my implementation is independent from the btrfs one, and might differ
+from what the paper describes.
+
+The distinctive feature of this B-tree is that a node is never
+modified (sort-of). Instead, all updates are done by
+copy-on-write. Among other things, this makes it easy to clone a tree,
+and modify only the clone, while other processes access the original
+tree. This is utterly wonderful for my backup application, and that's
+the reason I wrote larch in the first place.
+
+I have tried to keep the implementation generic and flexible, so that
+you may use it in a variety of situations. For example, the tree
+itself does not decide where its nodes are stored: you provide a class
+that does that for it. I have two implementations of the NodeStore
+class, one for in-memory and one for on-disk storage.
+
+The tree attempts to guarantee this: all modifications you make will
+be safely stored in the node store when the larch.Forest.commit method
+is called. After that, unless you actually modify the committed tree
+yourself, it will be safe from further modifications. (You need to
+take care to create a new tree for further modifications, though.)
