 Release Procedure
 =================
 
-This section needs to be updated to take into account features from gnulib.
-In particular, be sure to read README-release.
-
-## Update the submodules.  See above.
-
-## Update maintainer tools, such as Autoconf.  See above.
-
-## Try to get the *.pot files to the Translation Project at least one
-week before a stable release, to give them time to translate them.  Before
-generating the *.pot files, make sure that po/POTFILES.in and
-runtime-po/POTFILES.in list all files with translatable strings.  This
-helps: `grep -l '\<_(' *`.
-
-## Tests
-See above.
-
-## Update the foreign files
-Running `./bootstrap` in the top level should update them all for you.  This
-covers PO files too.  Sometimes a PO file contains problems that causes it
-to be rejected by recent Gettext releases; please report these to the
-Translation Project.
-
-## Update README
-Make sure the information in README is current.  Most notably, make sure it
-recommends a version of GNU M4 that is compatible with the latest Bison
-sources.
-
-## Check copyright years.
-We update years in copyright statements throughout Bison once at the start
-of every year by running `make update-copyright`.  However, before a
-release, it's good to verify that it's actually been run.  Besides the
-copyright statement for each Bison file, check the copyright statements that
-the skeletons insert into generated parsers, and check all occurrences of
-`PACKAGE_COPYRIGHT_YEAR` in configure.ac.
-
-## Update NEWS, commit and tag.
-See do-release-commit-and-tag in README-release.  For a while, we used beta
-names such as `2.6_rc1`.  Now that we use gnulib in the release procedure,
-we must use `2.5.90`, which has the additional benefit of being properly
-sorted in `git tag -l`.
-
-## make alpha, beta, or stable
 See README-release.
 
-## Upload
-There are two ways to upload the tarballs to the GNU servers: using gnupload
-(from gnulib), or by hand.  Obviously prefer the former.  But in either
-case, be sure to read the following paragraph.
-
-### Setup
-You need `gnupg`.
-
-Make sure your public key has been uploaded at least to keys.gnupg.net.  You
-can upload it with:
-
-  gpg --keyserver keys.gnupg.net --send-keys F125BDF3
-
-where F125BDF3 should be replaced with your key ID.
-
-### Using gnupload
-You need `ncftp`.
-
-At the end `make stable` (or alpha/beta) will display the procedure to run.
-Just copy and paste it in your shell.
-
-### By hand
-
-The generic GNU upload procedure is at
-http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads.
-
-Follow the instructions there to register your information so you're permitted
-to upload.
-
-Here's a brief reminder of how to roll the tarballs and upload them:
-
-### make distcheck
-### gpg -b bison-2.3b.tar.gz
-### In a file named `bison-2.3b.tar.gz.directive`, type:
-
-    version: 1.1
-    directory: bison
-    filename: bison-2.3b.tar.gz
-
-### gpg --clearsign bison-2.3b.tar.gz.directive
-### ftp ftp-upload.gnu.org # Log in as anonymous.
-### cd /incoming/alpha # cd /incoming/ftp for full release.
-### put bison-2.3b.tar.gz # This can take a while.
-### put bison-2.3b.tar.gz.sig
-### put bison-2.3b.tar.gz.directive.asc
-### Repeat all these steps for bison-2.3b.tar.xz.
-
-## Update Bison manual on www.gnu.org.
-
-The instructions below are obsolete, and left in case one would like to run
-the commands by hand.  Today, one just needs to run
-
-    $ make web-manual-update
-
-See README-release.
-
-### You need a non-anonymous checkout of the web pages directory.
-
-    $ cvs -d address@hidden:/web/bison checkout bison
-
-### Get familiar with the instructions for web page maintainers.
-http://www.gnu.org/server/standards/readme_index.html
-http://www.gnu.org/server/standards/README.software.html
-especially the note about symlinks.
-
-### Build the web pages.
-Assuming BISON_CHECKOUT refers to a checkout of the Bison dir, and
-BISON_WWW_CHECKOUT refers to the web directory created above, do:
-
-    $ cd $BISON_CHECKOUT/doc
-    $ make stamp-vti
-    $ ../build-aux/gendocs.sh -o "$BISON_WWW_CHECKOUT/manual" \
-      bison "Bison - GNU parser generator"
-    $ cd $BISON_WWW_CHECKOUT
-
-Verify that the result looks sane.
-
-### Commit the modified and the new files.
-
-### Remove old files.
-Find the files which have not been overwritten (because they belonged to
-sections that have been removed or renamed):
-
-     $ cd manual/html_node
-     $ ls -lt
-
-Remove these files and commit their removal to CVS.  For each of these
-files, add a line to the file .symlinks.  This will ensure that hyperlinks
-to the removed files will redirect to the entire manual; this is better than
-a 404 error.
-
-## Announce
-The "make release" command just created a template,
-`$HOME/announce-bison-X.Y`.  Otherwise, to generate it, run:
-
-    make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement
-
-where alpha can be replaced by `beta` or `table` and F125BDF3 should be
-replaced with your key ID.
-
-Complete/fix the announcement file.  The generated list of recipients
-(address@hidden, address@hidden, address@hidden,
-address@hidden, address@hidden, and
-address@hidden) is appropriate for a stable release or a
-"serious beta".  For any other release, drop at least address@hidden.  For
-an example of how to fill out the rest of the template, search the mailing
-list archives for the most recent release announcement.
-
-For a stable release, send the same announcement on the comp.compilers
-newsgroup by sending email to address@hidden.  Do not make any Cc as the
-moderator will throw away anything cross-posted or Cc'ed.  It really needs
-to be a separate message.
-
-## Prepare NEWS
-So that developers don't accidentally add new items to the old NEWS entry,
-create a new empty entry in line 3 (without the two leading spaces):
-
-  * Noteworthy changes in release ?.? (????-??-??) [?]
-
-Push these changes.
-
