136# a comment. Each field is delimited by a starting '>' and a
137# finishing '<'; any whitespace outside these start and end marks is
138# not part of the field. If formatting requires more than one data
139# item (for example, if variable field widths are used), the Perl data
140# expression should return a reference to an array having the requisite
141# number of elements. Even so, subterfuge is sometimes required: see
142# tests for %n and %p.
143#
144# Tests that are expected to fail on a certain OS can be marked as such
145# by trailing the comment with a skip: section. Skips are tags separated
146# bu space consisting of a $^O optionally trailed with :osvers. In the
147# latter case, all os-levels below that are expected to fail. A special
148# tag 'all' is allowed for todo tests that should fail on any system
