* The classic hello world program, with a twist - prints a message

* from the command line at every Place.
|
|
* The messages from each Place may appear in any order, but the
|
|
* finish ensures that the last message printed will be "Goodbye"
|

* <pre>
|
|
* Typical output:
|
|
* [dgrove@linchen samples]$ ./HelloWholeWorld 'best wishes'
|
|
* Place(1) says hello and best wishes
|
|
* Place(2) says hello and best wishes
|
|
* Place(3) says hello and best wishes
|
|
* Place(0) says hello and best wishes
|
|
* Goodbye
