-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.
