+Lambdanator (λ)
+===============
+
+A teeny-tiny static reflection class.
+
+
+Usage
+-----
+
+Just copy [Lambda.cs](/jagregory/lambdanator/blob/master/Lambda.cs) into your project and you're away!
+
+You can clone this repository and build it from source if you want an assembly, or if you want to run the tests.
+
+
+Examples
+--------
+
+    λ.Reflect<SomeClass>(x => x.AMethod());
+
+    λ.Reflect<SomeClass>(x => x.AProperty);
+
+    λ.Reflect(() => local);
+
+If you don't like the `λ` syntax, you can use `Lambda` instead.
+
+    Lambda.Reflect<SomeClass>(x => x.AMethod());
+
+    Lambda.Reflect<SomeClass>(x => x.AProperty);
+
+    Lambda.Reflect(() => local);
+
+
+License
+-------
+
+New BSD, leave it at the top of the file, but otherwise do as you please just don't blame me if it blows up.
