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