 dnl Macro to add for using GNU gettext.
 
 dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl INTLSYMBOL must be one of 'external', 'use-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages other than GNU gettext, and
+dnl    'use-libtool' for the packages 'gettext-runtime' and 'gettext-tools'.
 dnl    If INTLSYMBOL 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). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl    AM-DISABLE-SHARED).
 dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
 dnl    implementations (in libc or libintl) without the ngettext() function
 dnl    will be ignored.  If NEEDSYMBOL is specified and is
 dnl    'need-formatstring-macros', then GNU gettext implementations that don't
 dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
 dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
+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
