* Remove  files by renaming them.  We add '-' to the name, and we make a check *
* for the target existing, recursively removing it, too.  The result is a list *
* of files with more and more hyphens on the end of their names.               *

* The BACKUPS environment variable, if it exists and is a number, is the limit *
* to the number of backups that will be made; the default is 8.                *

* A difference from /bin/rm is that this program doesn't  consider  a  missing *
* file  to  be an error.  A nonzero exit status is given if there are bpfailed *
* due to permission problems, but no-such-file is not an error.                *
