This is the GNU implementation of sed, the Unix stream editor.

GNU Sed website: https://www.gnu.org/software/sed/

See the NEWS file for a brief summary and the ChangeLog for
more detailed descriptions of changes.

If you obtained this file as part of a "git clone", then see the
README-hacking file.  If this file came to you as part of a tar archive,
then see the file INSTALL for compilation and installation instructions.

See the file BUGS for instructions about reporting bugs.

See the files AUTHORS and THANKS for a list of authors and other contributors.

After installation run 'sed --help' or 'man sed' for short usage information,
and 'info sed' for the complete manual. The manual is also available on
sed's website.

These notes intend to help people working on the checked-out sources.
These requirements do not apply when building from a distribution tarball.

* 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.
Note the requirements to build the released archive are much less and
are just the requirements of the standard ./configure && make procedure.
Specific development tools and versions will be checked for and listed by
the bootstrap script.  See README-prereq for specific notes on obtaining
these prerequisite tools.

Valgrind <http://valgrind.org/> is also highly recommended, if
Valgrind supports your architecture. See also README-valgrind.

While building from a just-cloned source tree may require installing a
few prerequisites, later, a plain 'git pull && make' should be sufficient.

* First GIT checkout

You can get a copy of the source repository like this:

        $ git clone git://git.sv.gnu.org/sed
        $ cd sed

As an optional step, if you already have a copy of the gnulib git
repository on your hard drive, then you can use it as a reference to
reduce download time and disk space requirements:

        $ export GNULIB_SRCDIR=/path/to/gnulib

The next step is to get and check other files needed to build,
which are extracted from other source packages:

        $ ./bootstrap

To use the most-recent gnulib (as opposed to the gnulib version that
the package last synchronized to), do this next:

        $ git submodule foreach git pull origin master
        $ git commit -m 'build: update gnulib submodule to latest' gnulib

And there you are!  Just

        $ ./configure --quiet #[--enable-gcc-warnings] [*]
        $ make
        $ make check

At this point, there should be no difference between your local copy,
and the GIT master copy:

        $ git diff

should output no difference.

Enjoy!

[*] The --enable-gcc-warnings option is useful only with glibc
and with a very recent version of gcc.  You'll probably also have
to use recent system headers.  If you configure with this option,
and spot a problem, please be sure to send the report to the bug
reporting address of this package, and not to that of gnulib, even
if the problem seems to originate in a gnulib-provided file.
