+Avoid trailing white space
+==========================
+You may notice that the only trailing blanks in coreutils'
+version-controlled files are in a single directory: tests/pr,
+which contains expected output from various invocations of pr.
+
+Do not add any more trailing blanks anywhere.  While "make syntax-check"
+will alert you if you slip up, it's better to nip any problem in the
+bud, as you're typing.  A good way to help you adapt to this rule is
+to configure your editor to highlight any offending characters in the
+files you edit.  If you use Emacs, customize its font-lock mode (FIXME:
+provide more detail) or try one of its whitespace packages.  This appears
+to be the one that will end up in emacs 23:
+
+    http://www.emacswiki.org/emacs/WhiteSpace
+
+[that page says its version also works with emacs 21 and 22]
+If you use vim, add this to ~/.vimrc:
+
+    let c_space_errors=1
+    highlight RedundantSpaces ctermbg=red guibg=red
+    match RedundantSpaces /\s\+$\| \+\ze\t/
+
+
+Git can help too, by stopping you from committing any change that would
+add trailing blanks.  The example pre-commit hook contains code to check
+for trailing whitespace and spaces before tabs; enable it by moving it
+to the right place and making sure it is executable:
+
+    mv .git/hooks/pre-commit.sample .git/hooks/pre-commit
+
+With a repository created by git-1.5.6 or older, use this command:
+
+    chmod +x .git/hooks/pre-commit
+
+To manually check for whitespace errors before committing, you can use
+
+    git diff --check
+
+Git also has some settings to enable suitable internal whitespace checks.
+See the manpage for git-apply for details.

+* Noteworthy changes in release 7.2 (2009-03-31) [stable]
+
+** New features
+
+  pwd now accepts the options --logical (-L) and --physical (-P).  For
+  compatibility with existing scripts, -P is the default behavior
+  unless POSIXLY_CORRECT is requested.
+
+** Bug fixes
+
+  cat once again immediately outputs data it has processed.
+  Previously it would have been buffered and only output if enough
+  data was read, or on process exit.
+  [bug introduced in coreutils-6.0]
+
+  comm's new --check-order option would fail to detect disorder on any pair
+  of lines where one was a prefix of the other.  For example, this would
+  fail to report the disorder: printf 'Xb\nX\n'>k; comm --check-order k k
+  [bug introduced in coreutils-7.0]
+
+  cp once again diagnoses the invalid "cp -rl dir dir" right away,
+  rather than after creating a very deep dir/dir/dir/... hierarchy.
+  The bug strikes only with both --recursive (-r, -R) and --link (-l).
+  [bug introduced in coreutils-7.1]
+
+  ls --sort=version (-v) sorted names beginning with "." inconsistently.
+  Now, names that start with "." are always listed before those that don't.
+
+  pr: fix the bug whereby --indent=N (-o) did not indent header lines
+  [bug introduced in coreutils-6.9.90]
+
+  sort now handles specified key ends correctly.
+  Previously -k1,1b would have caused leading space from field 2 to be
+  included in the sort while -k2,3.0 would have not included field 3.
+
+** Changes in behavior
+
+  cp,mv,install,cat,split: now read and write a minimum of 32KiB
+  at a time.  This was seen to increase throughput.  Up to 2 times
+  when reading cached files on linux for example.
+
+  cp -a now tries to preserve extended attributes (xattr), but does not
+  diagnose xattr-preservation failure.  However, cp --preserve=all still does.
+
+  ls --color: hard link highlighting can be now disabled by changing the
+  LS_COLORS environment variable. To disable it you can add something like
+  this to your profile: eval `dircolors | sed s/hl=[^:]*:/hl=:/`
+
+
+* Noteworthy changes in release 7.1 (2009-02-21) [stable]
+
+** New features
+
+  Add extended attribute support available on certain filesystems like ext2
+  and XFS.
+    cp: Tries to copy xattrs when --preserve=xattr or --preserve=all specified
+    mv: Always tries to copy xattrs
+    install: Never copies xattrs
+
+  cp and mv accept a new option, --no-clobber (-n): silently refrain
+  from overwriting any existing destination file
+
+  dd accepts iflag=cio and oflag=cio to open the file in CIO (concurrent I/O)
+  mode where this feature is available.
+
+  install accepts a new option, --compare (-C): compare each pair of source
+  and destination files, and if the destination has identical content and
+  any specified owner, group, permissions, and possibly SELinux context, then
+  do not modify the destination at all.
+
+  ls --color now highlights hard linked files, too
+
+  stat -f recognizes the Lustre file system type
+
+** Bug fixes
+
+  chgrp, chmod, chown --silent (--quiet, -f) no longer print some diagnostics
+  [bug introduced in coreutils-5.1]
+
+  cp uses much less memory in some situations
+
+  cp -a now correctly tries to preserve SELinux context (announced in 6.9.90),
+  doesn't inform about failure, unlike with --preserve=all
+
+  du --files0-from=FILE no longer reads all of FILE into RAM before
+  processing the first file name
+
+  seq 9223372036854775807 9223372036854775808 now prints only two numbers
+  on systems with extended long double support and good library support.
+  Even with this patch, on some systems, it still produces invalid output,
+  from 3 to at least 1026 lines long. [bug introduced in coreutils-6.11]
+
+  seq -w now accounts for a decimal point added to the last number
+  to correctly print all numbers to the same width.
+
+  wc --files0-from=FILE no longer reads all of FILE into RAM, before
+  processing the first file name, unless the list of names is known
+  to be small enough.
+
+** Changes in behavior
+
+  cp and mv: the --reply={yes,no,query} option has been removed.
+  Using it has elicited a warning for the last three years.
+
+  dd: user specified offsets that are too big are handled better.
+  Previously, erroneous parameters to skip and seek could result
+  in redundant reading of the file with no warnings or errors.
+
+  du: -H (initially equivalent to --si) is now equivalent to
+  --dereference-args, and thus works as POSIX requires
+
+  shred: now does 3 overwrite passes by default rather than 25.
+
+  ls -l now marks SELinux-only files with the less obtrusive '.',
+  rather than '+'.  A file with any other combination of MAC and ACL
+  is still marked with a '+'.
+
+
+* Noteworthy changes in release 7.0 (2008-10-05) [beta]
+
+** New programs
+
+  timeout: Run a command with bounded time.
+  truncate: Set the size of a file to a specified size.
+
+** New features
+
+  chgrp, chmod, chown, chcon, du, rm: now all display linear performance,
+  even when operating on million-entry directories on ext3 and ext4 file
+  systems.  Before, they would exhibit O(N^2) performance, due to linear
+  per-entry seek time cost when operating on entries in readdir order.
+  Rm was improved directly, while the others inherit the improvement
+  from the newer version of fts in gnulib.
+
+  comm now verifies that the inputs are in sorted order.  This check can
+  be turned off with the --nocheck-order option.
+
+  comm accepts new option, --output-delimiter=STR, that allows specification
+  of an output delimiter other than the default single TAB.
+
+  cp and mv: the deprecated --reply=X option is now also undocumented.
+
+  dd accepts iflag=fullblock to make it accumulate full input blocks.
+  With this new option, after a short read, dd repeatedly calls read,
+  until it fills the incomplete block, reaches EOF, or encounters an error.
+
+  df accepts a new option --total, which produces a grand total of all
+  arguments after all arguments have been processed.
+
+  If the GNU MP library is available at configure time, factor and
+  expr support arbitrarily large numbers.  Pollard's rho algorithm is
+  used to factor large numbers.
+
+  install accepts a new option --strip-program to specify the program used to
+  strip binaries.
+
+  ls now colorizes files with capabilities if libcap is available
+
+  ls -v now uses filevercmp function as sort predicate (instead of strverscmp)
+
+  md5sum now accepts the new option, --quiet, to suppress the printing of
+  'OK' messages.  sha1sum, sha224sum, sha384sum, and sha512sum accept it, too.
+
+  sort accepts a new option, --files0-from=F, that specifies a file
+  containing a null-separated list of files to sort.  This list is used
+  instead of filenames passed on the command-line to avoid problems with
+  maximum command-line (argv) length.
+
+  sort accepts a new option --batch-size=NMERGE, where NMERGE
+  represents the maximum number of inputs that will be merged at once.
+  When processing more than NMERGE inputs, sort uses temporary files.
+
+  sort accepts a new option --version-sort (-V, --sort=version),
+  specifying that ordering is to be based on filevercmp.
+
+** Bug fixes
+
+  chcon --verbose now prints a newline after each message
+
+  od no longer suffers from platform bugs in printf(3).  This is
+  probably most noticeable when using 'od -tfL' to print long doubles.
+
+  seq -0.1 0.1 2 now prints 2,0 when locale's decimal point is ",".
+  Before, it would mistakenly omit the final number in that example.
+
+  shuf honors the --zero-terminated (-z) option, even with --input-range=LO-HI
+
+  shuf --head-count is now correctly documented.  The documentation
+  previously claimed it was called --head-lines.
+
+** Improvements
+
+  Improved support for access control lists (ACLs): On MacOS X, Solaris 7..10,
+  HP-UX 11, Tru64, AIX, IRIX 6.5, and Cygwin, "ls -l" now displays the presence
+  of an ACL on a file via a '+' sign after the mode, and "cp -p" copies ACLs.
+

 * Requirements
 
 We've opted to keep only the highest-level sources in the GIT repository.
 This eases our maintenance burden, (fewer merges etc.), but imposes more
 requirements on anyone wishing to build from the just-checked-out sources.
-For example, you have to use the latest stable versions of the maintainer

+Specific tools and versions will be checked for and listed by the
+bootstrap script shown below, and will include:
 
 - Automake <http://www.gnu.org/software/automake/>

-If you do want to build LZMA tarballs, you'll need to make sure you

-<http://tukaani.org/lzma/>.  Also, you'll need a version of
-Automake that supports the dist-lzma feature, like automake-1.10.1.

+Detailed below are concrete examples for
+getting the prerequisites for particular systems.
+
+- linux - fedora
+
+  This shows the steps for getting the required tools to build coreutils 7.0
+  on a Fedora 8 system. We try to use official packages where possible.
+  The 3 methods described for making these required packages available, should
+  help clarify build requirements on any linux system at least.
+
+  1. Make sure offical distro git package is installed
+    # yum install git
+
+  2. The distro autoconf is too old, but there is a newer one available
+  so we rebuild that and make it available to the full system:
+    # yum install emacs #autoconf build requires emacs (20MB)
+    # rpmbuild --rebuild http://download.fedora.redhat.com/pub/fedora/linux/development/source/SRPMS/autoconf-2.63-1.fc10.src.rpm
+    # rpm -Uvh /usr/src/redhat/RPMS/noarch/autoconf-2.63-1.fc8.noarch.rpm
+  Note Autoconf 2.61a-341 or newer is needed to build automake-1.10a in step 3.
+  Apply the same method to install the lzma package.
+  [FIXME: mention xz when it's packaged]
+
+  3. The latest released automake (1.10.1) was not new enough, so we download
+  and build automake-1.10a from its repository and make it available
+  just to coreutils:
+    # yum install help2man #required to build automake fully
+    $ git clone git://git.sv.gnu.org/automake.git
+    $ cd automake && ./configure --prefix=$HOME/coreutils/deps
+    $ make install
+
+  Now we can build coreutils as described in README-hacking
+  as long as $PATH starts with $HOME/coreutils/deps

+Here are most of the steps we (maintainers) follow when making a release.
+
+* start from a clean, up-to-date git directory.
+
+    git checkout master; git pull
+
+* Run ./configure && make maintainer-clean
+
+* Ensure that the desired versions of autoconf, automake, bison, etc.
+  are in your PATH.  See HACKING for the complete list.
+
+* Ensure that you're on "master" with no uncommitted diffs.
+  This should produce no output: git checkout master; git diff
+
+* Make sure your local gnulib directory is up to date.
+
+* Run bootstrap, (assuming your local copy of gnulib is in /gnulib):
+  ./bootstrap --gnulib-srcdir=/gnulib
+
+FIXME: enable excluded programs like arch? to get their manual pages?
+
+* Pre-release testing:
+  On at least one SELinux-enabled (enforcing) and one non-SELinux system,
+    run all tests, both root-only and regular.
+  Run *all* non-root tests, including expensive and very expensive ones i.e.,
+    run this: make check RUN_VERY_EXPENSIVE_TESTS=yes RUN_EXPENSIVE_TESTS=yes
+
+  Run the root-only tests:
+  sudo env PATH="$PATH" NON_ROOT_USERNAME=$USER make -k check-root
+
+* Run "make distcheck"
+
+* Manually set the date, version number, and [stable/alpha/beta] on
+  line 3 of NEWS, then do this:
+
+    v=7.1
+    git commit -F <(printf 'version '$v'\n\n* NEWS: Record release date.\n') -a
+    git tag -s -m "coreutils $v" v$v HEAD
+
+* Run the following to create release tarballs.  Your choice selects the
+  corresponding upload-to destination in the emitted gnupload command.
+
+    # "TYPE" must be major, beta or alpha
+    make TYPE
+
+* Test the tarball.  copy it to a few odd-ball systems and ensure that
+  it builds and passes all tests.
+
+* While that's happening, write the release announcement that you will
+  soon post.
+
+Once all the builds and tests have passed,
+
+* Run the gnupload command suggested by your "XZ_OPT=-9e make major" run above.
+
+* Wait a few minutes (maybe up to 30?) and then use the release URLs to
+  download all tarball/signature pairs and use gpg --verify to ensure
+  that they're all valid.
+
+* Push the new tag:
+  git push origin tag v<JUST_RELEASED_VERSION_NUMBER>
+
+* Send the gpg-signed announcement mail, e.g.,
+    To: info-gnu@gnu.org, coreutils-announce@gnu.org
+    Cc: coordinator@translationproject.org, bug-coreutils@gnu.org
+    Subject: coreutils-7.1 released [stable]
+
+* Approve the announcement here:
+  http://lists.gnu.org/mailman/admindb/coreutils-announce
+
+* Announce it on Savannah, too:
+  From here:
+    https://savannah.gnu.org/projects/coreutils/
+  click on the "submit news", then write something like the following:
+
+    The announcement is here:
+      http://article.gmane.org/gmane.comp.gnu.core-utils.announce/48
+
+  Then go here to approve it:
+    https://savannah.gnu.org/news/approve.php?group=coreutils
+
+* For non-alpha releases, update the on-line manual at
+
+    http://www.gnu.org/software/coreutils/manual/
+
+  Run `make web-manual', then copy the contents of doc/manual
+  into a CVS checkout of the coreutils manual repository.
+  Also edit coreutils.html (FIXME? why?) before doing a CVS commit.
+
+    CVS_RSH=ssh \
+    cvs -d:ext:$USER@cvs.savannah.gnu.org:/web/coreutils co coreutils
+
+  Be sure to "cvs add -ko" any files that "cvs status" marks with "?".
+  That is necessary whenever a new texinfo node is added.  Each becomes
+  a new file in html_node that must then be "cvs add"ed.
