In Version: 4.4.2-4ubuntu1, the info doc for --execdir says ``The
command is executed in the directory in which `find' was run.''
However, the doc for --exec says essentially the same thing: ``The
main difference is that the command is executed in the directory from
which `find' was invoked ...''
find 4.1.20 takes a "-newer" option that lets me specify a file; find will then
tell me about files that are newer than it. But I often want to find files that
are newer than a particular date; in order to get what I want, I have to create
a temporary file, and use "touch" to set its last-mod time
