/*
 * The side jobs on the ground (see the story, roadmap 4):
 *
 * - The Kartoffelacker's grass: knee high, mown with the scythe (the ground
 *   is too uneven for a mower). The field is cut into cells
 *   (World.mown: 0 standing .. FIELD_MOWN mown, FIELD_OFF not to be mown:
 *   under the stage); each swing over a cell takes it a step down.
 * - The vineyard snails (OBJ_SNAIL, protected): in the field and round the
 *   Obstwiese. Picked up into a bucket (Object.snails) and let go at the
 *   refuge by the strip of wood; mown over, a snail is dead. The regulatory
 *   office comes at FIELD_INSPECTION hours on the ground (game_story.c).
 * - Kerry's wood art: a log lying at the art spot, carved with the chainsaw
 *   into a figure (OBJ_SCULPTURE).
