Subject: Rewrite release script to use GIT.
X-Git-Tag: v0.3.0-rc0~5
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=e8dc384be9d4bf2b7ed61178c02154dffdb15a9e;p=openocd

Rewrite release script to use GIT.

Update documentation to reflect GIT methodology.  Rewrite release.sh
script to use appropriate process.  With this update, tools/release.sh
can be used for producing private release tags on local branches.
The documentation still needs work, but their use for v0.3.x should
help rectify the deficiences.

+The release script can be used for two tasks:
+- Creating releases and starting a new release cycle:
+@code
+git checkout master
+tools/release.sh --type=minor --final --start-rc release
+@endcode
+- Creating a development branch from a tagged release:
+@code
+git checkout 'v0.2.0'

-Run <code>tools/release.sh help</code> for current command support.

+proceding with a live release.
 
 @subsection releasescriptopts Release Script Options
 
 The @c release.sh script recognizes some command-line options that
 affect its behavior:
 
-- @c --live : Use this option to perform a live release.
-  When this option has been given, the release commands will affect
-  the repository; otherwise, the script reports the actions to take,
-  and it produces archives that are unsuitable for public release.
-
-@note Only the Release Manager should use the @c --live option, as
-it will make permanent changes to the git repository that
-cannot be undone.
+- The @c --start-rc indicates that the new development release cycle
+  should start with @c -rc0.  Without this, the @c -rc tag will be omitted,
+  leading to non-monotonic versioning of the in-tree version numbers.
+- The @c --final indicates that the release should drop the @c -rc tag,
+  to going from @c x.y.z-rcN-dev to x.y.z.
