-### Extensions to the "os" package.
-
-## Find the current Executable and ExecutableFolder.
-
-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.
