Subject: gnome-help.bbclass: Handle gnome-help files with new distro feature
 'helpfiles'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we can build gnome help files, let our users decide what to do with
them:

if 'helpfiles' not in DISTRO_FEATURES
    delete all help contents during install
else
  if PACKAGE_NO_HELP_SPLIT == 1
      pack all help files to ${PN}-help
  else
      pack help files to ${PN}-help-<lingua>
