+        Nettle is a cryptographic library that is designed to fit
+        easily in more or less any context: In crypto toolkits for
+        object-oriented languages (C++, Python, Pike, ...), in
+        applications like LSH or GNUPG, or even in kernel space.  In
+        most contexts, you need more than the basic cryptographic
+        algorithms, you also need some way to keep track of available
+        algorithms, their properties and variants.  You often have
+        some algorithm selection process, often dictated by a protocol
+        you want to implement.
+
+        And as the requirements of applications differ in subtle and
+        not so subtle ways, an API that fits one application well can
+        be a pain to use in a different context.  And that is why
+        there are so many different cryptographic libraries around.
+
+        Nettle tries to avoid this problem by doing one thing, the
+        low-level crypto stuff, and providing a simple but general
+        interface to it.  In particular, Nettle doesn't do algorithm
+        selection.  It doesn't do memory allocation. It doesn't do any
+        I/O.
