4 *  DESCRIPTION:
5 *
6 *  This package is the implementation of the Semaphore Manager.
7 *  This manager utilizes standard Dijkstra counting semaphores to provide
8 *  synchronization and mutual exclusion capabilities.
9 *
10 *  Directives provided are:
11 *
12 *     + create a semaphore
13 *     + get an ID of a semaphore
14 *     + delete a semaphore
15 *     + acquire a semaphore
16 *     + release a semaphore
