A test of how Liquid Template language evaluates YAML Front Matter variables of the truthy, falsy type. Meant for debugging Jekyll templates.

# Each value of 'single' in 'yaml-results-truthy.yml' was run
# through each of these '{% if %} clauses.
#
# If the '{% if %}' clause evaluated to truthy, the statement
# is shown in 'yaml-results-truthy.yml' under the --- block
# for that value of 'single'.
# If falsy, nothing is printed and nothing was added to the
# results file.
