+Distributors of patched versions of OpenOCD are encouraged to extend the
+version string with a unique version tag when producing external
+releases, as this helps to identify your particular distribution series.

+For example, the following command will add a 'foo1' tag to the

+@code
+tools/release.sh version bump tag foo
+@endcode
+
+This command will modify the configure.in script in your working copy

+used each time the derived package is released, incrementing the tag's
