-# Process List Library for Go [![GoDoc](https://godoc.org/github.com/mitchellh/go-ps?status.png)](https://godoc.org/github.com/mitchellh/go-ps)
-
-go-ps is a library for Go that implements OS-specific APIs to list and
-manipulate processes in a platform-safe way. The library can find and
-list processes on Linux, Mac OS X, Solaris, and Windows.
-
-If you're new to Go, this library has a good amount of advanced Go educational
-value as well. It uses some advanced features of Go: build tags, accessing
-DLL methods for Windows, cgo for Darwin, etc.
-
-How it works:
-
-  * **Darwin** uses the `sysctl` syscall to retrieve the process table.
-  * **Unix** uses the procfs at `/proc` to inspect the process tree.
-  * **Windows** uses the Windows API, and methods such as
-    `CreateToolhelp32Snapshot` to get a point-in-time snapshot of
-    the process table.
-
-## Installation
-
-Install using standard `go get`:
-
-```
-$ go get github.com/mitchellh/go-ps
-...
-```
-
-## TODO
-
-Want to contribute? Here is a short TODO list of things that aren't
-implemented for this library that would be nice:
-
-  * FreeBSD support
-  * Plan9 support

+// Package binary implements simple translation between numbers and byte
+// sequences and encoding and decoding of varints.
+//
+// Numbers are translated by reading and writing fixed-size values.
+// A fixed-size value is either a fixed-size arithmetic
+// type (int8, uint8, int16, float32, complex64, ...)
+// or an array or struct containing only fixed-size values.
+//
+// The varint functions encode and decode single integer values using
+// a variable-length encoding; smaller values require fewer bytes.
+// For a specification, see
+// http://code.google.com/apis/protocolbuffers/docs/encoding.html.
+//
+// This package favors simplicity over efficiency. Clients that require
+// high-performance serialization, especially for large data structures,
+// should look at more advanced solutions such as the encoding/gob
+// package or protocol buffers.
