    48  * Determine the epoc root for the currently active SDK.

    49  *

    50  * The algorithm used is as follows:

    51  * 1. If environment variable EPOCROOT is set and points to an existent

    52  *    directory, this is returned.

    53  * 2. The location of devices.xml is specified by a registry key.  If this

    54  *    file exists, it is parsed.

    55  * 3. If the EPOCDEVICE environment variable is set and a corresponding

    56  *    entry is found in devices.xml, and its epocroot value points to an

    57  *    existent directory, it is returned.

    58  * 4. If a device element marked as default is found in devices.xml and its

    59  *    epocroot value points to an existent directory, this is returned.

    60  * 5. An empty string is returned.

    61  *

    62  * Any return value other than the empty string therefore is guaranteed to

    63  * point to an existent directory.
