# Add to your top-level meson.build to check for an updated NEWS file
# when doing a "dist" release, similarly to automake's check-news:
# https://www.gnu.org/software/automake/manual/html_node/List-of-Automake-options.html
#
# Checks NEWS for the version number:
# meson.add_dist_script(
#   find_program('check-news.sh').path(),
#   '@0@'.format(meson.project_version())
# )
#
# Checks NEWS and data/foo.appdata.xml for the version number:
# meson.add_dist_script(
#   find_program('check-news.sh').path(),
#   '@0@'.format(meson.project_version()),
#   'NEWS',
#   'data/foo.appdata.xml'
# )
