### 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.
Multi-platform and supports:
* Linux
* OS X
* Windows
* Plan 9
* BSDs.
