+
+A simple module for bitwise-xor on buffers.
+
+
+## Examples
+
+``` javascript
+var xor = require("buffer-xor")
+var a = new Buffer('00ff0f', 'hex')
+var b = new Buffer('f0f0', 'hex')
+
+console.log(xor(a, b))
+// => <Buffer f0 0f>
+```
+
+
+Or for those seeking those few extra cycles, perform the operation in place:
+
+``` javascript
+var xorInplace = require("buffer-xor/inplace")
+var a = new Buffer('00ff0f', 'hex')
+var b = new Buffer('f0f0', 'hex')
+
+console.log(xorInplace(a, b))
+// => <Buffer f0 0f>
+// NOTE: xorInplace will return the shorter slice of its parameters
+
+// See that a has been mutated
+console.log(a)
+// => <Buffer f0 0f 0f>
+```
