51# In each of the the following lines, there are three required fields:
52# printf template, data to be formatted (as a Perl expression), and
53# expected result of formatting. An optional fourth field can contain
54# a comment. Each field is delimited by a starting '>' and a
55# finishing '<'; any whitespace outside these start and end marks is
56# not part of the field. If formatting requires more than one data
57# item (for example, if variable field widths are used), the Perl data
58# expression should return a reference to an array having the requisite
59# number of elements. Even so, subterfuge is sometimes required: see
60# tests for %n and %p.
