HOWTO-RELEASE: 

Notes on releasing.

0. Make sure that you have current FSF releases of autoconf, automake,

   and libtool packages installed under a common installation prefix

   and that these tools are in your executable search path prior to

   any other installed versions.  Versions delivered with Linux may be

   altered so it is best to install official FSF releases. GNU 'm4'

   1.4.6 or later is needed in order to avoid bugs in m4. These

   packages may be downloaded from the following ftp locations:

     autoconf - ftp://ftp.gnu.org/pub/gnu/autoconf

     automake - ftp://ftp.gnu.org/pub/gnu/automake

     libtool  - ftp://ftp.gnu.org/pub/gnu/libtool

   Release builds should only be done on a system with a functioning

   and correctly set system clock and on a filesystem which accurately

   records file update times.  Use of GNU make is recommended.

1. Commit any unsaved changes. 

2. Create html/vX.X.html.  Take ChangeLog entries and html-ify in there. 

   Easist thing to do is take html/vX.(X-1).html and use it as a template.

   Add that file to the list of EXTRA_DIST files in the html/Makefile.am.

3. Update html/index.html to refer to this new page as the current release.

4. Increment the release version in configure.ac.  Put 'alpha' or

   'beta' after the version, if applicable.  For example:

     3.9.1

      or

     3.9.1beta

   Version should be updated in two places: in the second argument of the

   AC_INIT macro and in LIBTIFF_xxx_VERSION variables.

5. Add an entry to Changelog similar to:

     * libtiff 3.9.1 released.

6. In the source tree do

     ./autogen.sh

   This step may be skipped if you have already been using a

   maintainer build with current autoconf, automake, and libtool

   packages.  It is only needed when updating tool versions.

7. It is recommended (but not required) to build outside of the source

   tree so that the source tree is kept in a pristine state.  This

   also allows sharing the source directory on several networked

   systems.  For example:

     mkdir libtiff-build

     cd libtiff-build

     /path/to/libtiff/configure --enable-maintainer-mode

   otherwise do

     ./configure --enable-maintainer-mode

8. In the build tree do

     make release

   This will update "RELEASE-DATE", "VERSION", and libtiff/tiffvers.h

   in the source tree.

9. In the source tree, verify that the version info in RELEASE-DATE,

   VERSION and libtiff/tiffvers.h is right.

10. In the build tree do

      make

      make distcheck

    If 'make distcheck' fails, then correct any issues until it

    succeeds.

    Two files with names tiff-version.tar.gz and tiff-version.zip will

    be created in the top level build directory.

11. In the source tree do

      'cvs commit'.

12. In the source tree do

      cvs tag Release-v3-9-1

    (or the appropriate name for the release)

13. Copy release packages from the build tree to the

    ftp.remotesensing.org ftp site.

      scp tiff-*.tar.gz tiff-*.zip \

    	 frankw@upload.osgeo.org:/osgeo/download/libtiff

14. Announce to list, tiff@lists.maptools.org

15. Update libtiff page on freshmeat with new version announcement.
