Допустим, вы устанавливаете Python, и он оказывается в каталоге `/opt/custompython/bin`.

Если вы скажете «да», чтобы обновить переменную окружения `PATH`, то программа установки добавит `/opt/custompython/bin` в переменную окружения `PATH`.

Это может выглядеть следующим образом:

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/custompython/bin
```

        copy.setMirrors(original.getMirrors());
        copy.setProfiles(original.getProfiles());
        copy.setPluginGroups(original.getPluginGroups());
        copy.setProjectPresent(original.isProjectPresent());
        copy.setUserSettingsFile(original.getUserSettingsFile());
        copy.setInstallationSettingsFile(original.getInstallationSettingsFile());
        copy.setUserToolchainsFile(original.getUserToolchainsFile());

	return &SkipReader{r, n}
}

// writerOnly hides an io.Writer value's optional ReadFrom method
// from io.Copy.
type writerOnly struct {
	io.Writer

// Copy is exactly like io.Copy but with reusable buffers.

	defer ODirectPoolMedium.Put(bufp)
	buf := *bufp
