+### Extensions to the "os" package.
+
+[![GoDoc](https://godoc.org/github.com/kardianos/osext?status.svg)](https://godoc.org/github.com/kardianos/osext)
+
+## Find the current Executable and ExecutableFolder.
+
+As of go1.8 the Executable function may be found in `os`. The Executable function
+in the std lib `os` package is used if available.
+
+There is sometimes utility in finding the current executable file
+that is running. This can be used for upgrading the current executable
+or finding resources located relative to the executable file. Both
+working directory and the os.Args[0] value are arbitrary and cannot
+be relied on; os.Args[0] can be "faked".
+
+Multi-platform and supports:
+ * Linux
+ * OS X
+ * Windows
+ * Plan 9
+ * BSDs.
