dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
dnl    depending on --{enable,disable}-{shared,static} and on the presence of
dnl    AM-DISABLE-SHARED). Otherwise, a static library
dnl    $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl    implementations (in libc or libintl) without the ngettext() function
dnl    will be ignored.
dnl LIBDIR is used to find the intl libraries.  If empty,
dnl    the value `$(top_builddir)/intl/' is used.
dnl
dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl    and used.
dnl    Catalog format: GNU --> install in $(datadir)
dnl    Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl    Catalog format: GNU --> install in $(datadir)
dnl    Catalog extension: .mo after installation, .gmo in source tree
dnl 3) No internationalization, always use English msgid.
dnl    Catalog format: none
dnl    Catalog extension: none
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
dnl maintainers.
