sheet1: left

# "left" and "right" specify which page of a two-page spread a file
# must start on.  "left" means that a file must start on the first of
# the two pages.  "right" means it must start on the second of the two
# pages.  The file may start in either column.
#
# "even" and "odd" specify which column a file must start on.  "even"
# means it must start in the left of the two columns (00).  "odd" means it
# must start in the right of the two columns (50).
#
# You'd think these would be the other way around.
