This is a COPY of the documentation in CAR_SHARE/S/docs

Because of various security restrictions, we cannot seem to accomplish
access by symbolic links; hence we have copied.

The copy command is:

  cp /home/pjbrown/CAR_share/S/docs/* .

Since the directory also covers documents NOT generated by javadoc,
we need to move index.html (which was generated by javadoc, and just covers
the javadoc files).  The command is

  mv index.html javadoc.html

I also modified CAR*Ex* so that fewer lines get lost over the end when printing.
I replace all tabs by 4 spaces, and did some further editing of spaces before
comments.
