85# In each of the the following lines, there are three required fields:
86# printf template, data to be formatted (as a Perl expression), and
87# expected result of formatting. An optional fourth field can contain
88# a comment. Each field is delimited by a starting '>' and a
89# finishing '<'; any whitespace outside these start and end marks is
90# not part of the field. If formatting requires more than one data
91# item (for example, if variable field widths are used), the Perl data

93# number of elements. Even so, subterfuge is sometimes required: see
