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