dnl XDT_I18N([LINGUAS][, PACKAGE])
dnl
dnl This macro takes care of setting up everything for i18n support.
dnl
dnl If LINGUAS isn't specified, it will automatically extract the linguas
dnl from po/*.po.
dnl
dnl If PACKAGE isn't specified, it defaults to the package tarname; see
dnl the description of AC_INIT() for an explanation of what makes up
dnl the package tarname. Normally, you don't need to specify PACKAGE,
dnl but you can stick with the default.
