i recently noticed that rm has a -P option to do "simple" secure
deletion of files.  i don't read the rm man page that much, because
there's not much to it, so i imagine it's been there for a long time
and i just never noticed.

anyway...i had some free time and added support for

   http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html

to rm, specified by giving more than one -P on the command line.  it's
a "better" algorithm for secure file deletion, specifying 35 passes
over the file...probably to get around things like

   http://www.sciencenews.org/20000708/fob1.asp

so anyway...i finished my patch, and it seems to be doing the right
thing, so i was touching up the man page to reflect this and thought
that a reference to the paper found at the first url above would be a
good thing to include in the man page.  is there an established
practice for referencing things like this?
