# expected result of formatting. An optional fourth field can contain
# a comment. Each field is delimited by a starting '>' and a
# finishing '<'; any whitespace outside these start and end marks is
# not part of the field. If formatting requires more than one data
# item (for example, if variable field widths are used), the Perl data
# expression should return a reference to an array having the requisite
# number of elements. Even so, subterfuge is sometimes required: see
# tests for %n and %p.
