corresponding Python scripts.

- Find an existing extension that's similar to the new one and search
- the sources for code related to that extension.
- Implement new code as needed.
- In general, new state variables will be added to mtypes.h. If the
- extension is rather large, try to implement it in a new source file.
+ Add a new entry to the <code>gl_extensions</code> struct in mtypes.h
+</li>
+<li>
+ Update the <code>extensions.c</code> file.
</li>
<li>
- If hew extension adds new GL state, the functions in get.c, enable.c
+ From this point, the best way to proceed is to find another extension,
+ similar to the new one, that's already implemented in Mesa and use it
+ as an example.
+</li>
+<li>
+ If the new extension adds new GL state, the functions in get.c, enable.c
and attrib.c will most likely require new code.

Here's the GNU indent command which will best approximate my preferred style:
</p>
<pre>
- indent -br -i3 -npcs infile.c -o outfile.c
+ indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
</pre>
</p>

-Global vars not allowed.
+Global variables are not allowed.

Function name examples:
</p>
<pre>
- glFooBar() - a public GL entry point (in dispatch.c)
+ glFooBar() - a public GL entry point (in glapi_dispatch.c)
_mesa_FooBar() - the internal immediate mode function
save_FooBar() - retained mode (display list) function in dlist.c
foo_bar() - a static (private) function

<H2>Making a New Mesa Release</H2>
<p>
These are the instructions for making a new Mesa release.
</p>
+<H3>Get latest source files</H3>
<p>
-Prerequisites (later versions may work):
+Use git to get the latest Mesa files from the git repository, from whatever
+branch is relevant.
</p>
-<ul>
-<li> autoconf 2.50
-<li> automake 1.4-p2
-<li> libtool 1.4
-</ul>
-<p>
-Be sure to do a "cvs update -d ." in the Mesa directory to
-get all the latest files.
-</p>
+<H3>Verify and update version info</H3>
<p>
-Update the version definitions in src/version.h
+Create/edit the docs/relnotes-x.y.html file to document what's new in the release.
+Add the new relnotes-x.y.html file to <a href="relnotes.html">relnotes.html</a>.
</p>
<p>
-Create/edit the docs/RELNOTES-X.Y file to document what's new in the release.
-Edit the docs/VERSIONS file too.
+Update the MESA_MAJOR, MESA_MINOR and MESA_TINY version numbers in
+configs/default.
+Also update the VERSION line in the top-level Makefile.
</p>
<p>
-Edit Make-config and change the MESA_MAJOR and/or MESA_MINOR versions.
+Make sure the values in src/mesa/main/version.h are correct.
</p>
<p>
-Edit the GNU configure stuff to change versions numbers as needed:
-Update the version string (second argument) in the line
-"AM_INIT_AUTOMAKE(Mesa, 3.3)" in the configure.in file.
+Update docs/news.html.
</p>
<p>
-Remove the leading `dnl' from the line "dnl AM_MAINTAINER_MODE".
+Check in all updates to git.
</p>
<p>
-Verify the version numbers near the top of configure.in
+Tag the files with the release name (in the form <b>mesa_X_Y</b>)
+with: <code>git tag -a mesa_X_Y</code>
+Then: <code>git push origin mesa_X_Y</code>
</p>
-<p>
-Run "fixam -f" to disable automatic dependency tracking.
-</p>
+<H3>Make the tarballs</H3>
<p>
-Run the bootstrap script to generate the configure script.
-</p>
-
-<p>
-Edit Makefile.X11 and verify DIRECTORY is set correctly. The Mesa
-sources must be in that directory (or there must be a symbolic link).
-</p>
-
-<p>
-Edit Makefile.X11 and verify that LIB_NAME and DEMO_NAME are correct.
-If it's a beta release, be sure the bump up the beta release number.
-</p>
+Make the distribution files. From inside the Mesa directory:
+<pre>
+ make tarballs
+</pre>
<p>
-cp Makefile.X11 to Makefile so that the old-style Mesa makefiles
-still work. ./configure will overwrite it if that's what the user runs.
+After the tarballs are created, the md5 checksums for the files will
+be computed.
+Add them to the docs/relnotes-X.Y.html file.
</p>
<p>
-Make a symbolic link from $(DIRECTORY) to Mesa. For example,
-ln -s Mesa Mesa-3.3 This is needed in order to make a correct
-tar file in the next step.
+Copy the distribution files to a temporary directory, unpack them,
+compile everything, and run some demos to be sure everything works.
</p>
+<H3>Update the website and announce the release</H3>
<p>
-Make the distribution files. From inside the Mesa directory:
-<pre>
- make -f Makefile.X11 lib_tar
- make -f Makefile.X11 demo_tar
- make -f Makefile.X11 lib_zip
- make -f Makefile.X11 demo_zip
-</pre>
-
-<p>
-Copy the distribution files to a temporary directory, unpack them,
-compile everything, and run some demos to be sure everything works.
+Follow the directions on SourceForge for creating a new "release" and
+uploading the tarballs.
</p>
<p>
-Upload the *.tar.gz and *.zip files to ftp.mesa3d.org
+Basically, to upload the tarball files with:
+<br>
+<code>
+rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/
+</code>
</p>
<p>
-Update the web site.
+Update the web site by copying the docs/ directory's files to
+/home/users/b/br/brianp/mesa-www/htdocs/ with:
+<br>
+<code>
+sftp USERNAME,mesa3d@web.sourceforge.net
+</code>
</p>
