dnl APPSTREAM_XML

dnl Installs and validates AppData XML files.

dnl

dnl Call APPSTREAM_XML in configure.ac to check for the appstream-util tool.

dnl Add @APPSTREAM_XML_RULES@ to a Makefile.am to substitute the make rules. Add

dnl .appdata.xml files to appstream_XML in Makefile.am and they will be validated

dnl at make check time, if appstream-util is installed, as well as installed

dnl to the correct location automatically. Add --enable-appstream-util to

dnl AM_DISTCHECK_CONFIGURE_FLAGS in Makefile.am to require valid AppData XML when

dnl doing a distcheck.

dnl

dnl Adding files to appstream_XML does not distribute them automatically.
