It prints:

------------------------------------------------------------------
### pwd
/home/mccramer/data/pool10
/home/mccramer/data/pool10
### find
.
.
.
<print of the jpg-files>
.
.
.
### glob
------------------------------------------------------------------


The
"------------------------------------------------------------------"'s
are added by myself. After "### glob" there is following nothing
printed to stdout. To stderr there is the known error message:

		./globtest2:8: no matches found: **/*.jpg

(I called that script "globtest2"....)


Normally, in the root of the dirtree, where the jpgs are, there is no
jpg, but in the tree under the root there are jpgs (root ==
"/home/mccramer/data/pool10").

Now I did a 

	touch "test.jpg"

in the root and run the script again.
Now, this single fake jpg in the root was found by the glob pattern
'**/*.jpg'...but nothing else. 

By the way: What happens, when you run this script on your machine in
a similiar environment/ under similiar conditions, Phil? Does it work
for you ?
