+presumably because the file is growing.  This option is ignored when
+reading from a pipe.
 If more than one file is given, @code{tail} prints a header whenever it
 gets output from a different file, to indicate which file that output is
 from.
 
+There are two ways to specify how you'd like to track files with this option,
+but that difference is noticeable only when a followed file is removed.
+If you'd like to continue to track the end of a growing file even after
+it has been unlinked, use @samp{--follow=descriptor}.  This is the default
+behavior, but it is not useful if you're tracking a log file that may be
+rotated (removed and reopened).  In that case, use @samp{--follow=name} to
+track the named file by reopening it periodically
+@c FIXME: cross reference to the new option name
+to see if it has been removed and recreated by some other program.
+
+No matter which method you use, if the tracked file is determined to have
+shrunk, @code{tail} prints a message saying the file has been truncated
+and resumes tracking the end of the file from the newly-determined endpoint.
+
+When a file is removed, @code{tail}'s behavior depends on whether it is
+following the name or the descriptor.  When following by name, tail can
+detect that a file has been removed and gives a message to that effect,
+and if @samp{--allow-missing} has been specified it will continue checking
+periodically to see if the file reappears.
+When following a descriptor, tail does not detect that the file has
+been unlinked and issues no message.
+
+The option values @samp{descriptor} and @samp{name} may be specified only
+with the long form of the option, not with @samp{-f}.

+
+1998-11-07  Jim Meyering  <meyering@ascend.com>
+
+	* Version 4.0-b7.
+
+	Accommodate the Hurd (defining lstat to rpl_lstat via config.h didn't
+	work on Hurd systems because of an inline definition of lstat in a
+	system header file).  This also makes it so that you may run `ls '' '
+	on systems that let l?stat operate on the empty string.
+
+	* src/remove.c [HAVE_LSTAT_EMPTY_STRING_BUG]: Define lstat to rpl_lstat
+	and declare the latter.
+	* lib/stat.c [stat]: Remove #undef.

+

+	* tests/rm/Makefile.am (TESTS): Add new test `unreadable'.  But comment
+	it out since we're so close to release and since the test compares the
+	text of diagnostics that are likely to vary between systems.
+	(TEST_ENVIRONMENT): Add required framework.
+
+	* src/remove.c (remove_cwd_entries): Don't apply CLOSEDIR to a NULL
+	pointer. (provoke with `mkdir -m 0100 x; rm -rf x')
+	Upon CLOSEDIR failure, set `status' to RM_ERROR, not RM_OK.
+	(remove_dir): Return `status', rather than always RM_OK.
+
+1998-10-18  Jim Meyering  <meyering@ascend.com>
+
+	* Version 4.0-b5.
+
+	* lib/mktime.c: Update from libc with this additional change from Paul.
+	* lib/strftime.c: Likewise.
+
+	1998-10-17  Paul Eggert  <eggert@twinsun.com>
+
+	Don't invoke localtime_r or gmtime_r unless it's the GNU C
+	library's localtime_r and gmtime_r; there are too many buggy
+	implementations of localtime_r and gmtime_r out there, and
+	it's not worth keeping track of all the different bugs.
+
+	* mktime.c (__EXTENSIONS__, HAVE_LOCALTIME_R): Remove.
+	(my_mktime_localtime_r): Renamed from localtime_r; all uses changed.
+	Base it on localtime unless _LIBC.
+
+	* strftime.c (__EXTENSIONS__): Remove.
+	(my_strftime_gmtime_r): Renamed from gmtime_r; all uses changed.
