+# get-bytes
+
+get-bytes is a node module which returns the specified number of bytes from the beginning of each input file.
+
+`done` is a function provided by the mocha testing framework, which is passed as a parameter of the `it` function's callback. It is invoked after asynchronous processing is complete and the result of the test has been computed.
