# 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'

# )
