21dnl Usage: MUTT_AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR]).
22dnl If TOOLSYMBOL is specified and is 'use-libtool', then a libtool library
23dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
24dnl depending on --{enable,disable}-{shared,static} and on the presence of
25dnl AM-DISABLE-SHARED). Otherwise, a static library
26dnl $(top_builddir)/intl/libintl.a will be created.
27dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
28dnl implementations (in libc or libintl) without the ngettext() function
29dnl will be ignored.
30dnl LIBDIR is used to find the intl libraries. If empty,
31dnl the value `$(top_builddir)/intl/' is used.
32dnl
33dnl The result of the configuration is one of three cases:
34dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
35dnl and used.
36dnl Catalog format: GNU --> install in $(datadir)
37dnl Catalog extension: .mo after installation, .gmo in source tree
38dnl 2) GNU gettext has been found in the system's C library.
39dnl Catalog format: GNU --> install in $(datadir)
40dnl Catalog extension: .mo after installation, .gmo in source tree
41dnl 3) No internationalization, always use English msgid.
42dnl Catalog format: none
43dnl Catalog extension: none
44dnl The use of .gmo is historical (it was needed to avoid overwriting the
45dnl GNU format catalogs when building on a platform with an X/Open gettext),
46dnl but we keep it in order not to force irrelevant filename changes on the
47dnl maintainers.
