dnl Usage: AM_WITH_NLS([TOOLSYMBOL], [NEEDSYMBOL], [LIBDIR], [ENABLED]).
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 ENABLED is used to control the default for the related --enable-nls, since
dnl not all application developers want this feature by default, e.g., lynx.
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.

dnl -------------------
dnl Look for the SVr4 curses clone 'ncurses' in the standard places, adjusting
dnl the CPPFLAGS variable so we can include its header.
dnl
dnl The header files may be installed as either curses.h, or ncurses.h (would
dnl be obsolete, except that some packagers prefer this name to distinguish it
dnl from a "native" curses implementation). If not installed for overwrite,
dnl the curses.h file would be in an ncurses subdirectory (e.g.,
dnl /usr/include/ncurses), but someone may have installed overwriting the
dnl vendor's curses. Only very old versions (pre-1.9.2d, the first autoconf'd
dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
dnl the header.
dnl
dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
dnl is already in the include-path, don't even bother with this, since we cannot
dnl easily determine which file it is. In this case, it has to be <curses.h>.
dnl
dnl The optional parameter gives the root name of the library, in case it is
dnl not installed as the default curses library. That is how the
dnl wide-character version of ncurses is installed.

dnl Define several useful symbols derived from the VERSION file. A separate
dnl file is preferred to embedding the version numbers in various scripts.
dnl (automake is a textbook-example of why the latter is a bad idea, but there
dnl are others).
dnl
dnl The file contents are:
dnl libtool-version release-version patch-version
dnl or
dnl release-version
dnl where
dnl libtool-version (see ?) consists of 3 integers separated by '.'
dnl release-version consists of a major version and minor version
dnl separated by '.', optionally followed by a patch-version
dnl separated by '-'. The minor version need not be an
dnl integer (but it is preferred).
dnl patch-version is an integer in the form yyyymmdd, so ifdef's and
dnl scripts can easily compare versions.
dnl
dnl If libtool is used, the first form is required, since CF_WITH_LIBTOOL
dnl simply extracts the first field using 'cut -f1'.
dnl
dnl Optional parameters:
dnl $1 = internal name for package
dnl $2 = external name for package
