It is the current directory at the time the server excutable was started.
Perhaps you find the following wrapper helpful.  Note that two more
auxiliaries follow.  I think they will pass through Usenet unharmed
but you have to split them up yourself.  (I'm not going to use shar.)

# this script differs from 'ser' in two ways:
#
# - it uses $FREECIV_PATH or its default to locate a civserver binary
# - it uses separate working directories to store the game data
