It is possible to play the program against itself under winboard without a
special command so I do not see a reason for a special Auto command.

Every winboard program that support some commands under winboard can solve epd
test suites thanks to bruce moreland so the only reason to do special EPD
processing tool is if you want to calculate some statistics or if you do not
want to run every position for the same time or if you want to solve test suites
when the target is not to find move but to avoid move or to find move and a
minimal evaluation.
