Actually, that script removes every symbolic link that does not test
successfully as a regular file.  Yes, that test will follow the symbolic
link; but, it will only check whether or not the destination is a
regular file.  It does *NOT* test for dangling symlink at all!  On my
system, I have *many* symlinks to directories, all of which contain
something, and this script flags *ALL* of them for removal . . .

What could be the purpose of this script?
