This change seems reasonable.
><i> 2) handle README.*.(obsolete|deprecated).urpmi
</I>><i> In order to display informations about the deprecated or obsoleted
</I>><i> package(s), I suggest to handle 2 new kinds of README.*.urpmi:
</I>><i> - README."nameObsoletedPackage".obsolete.urpmi to inform about the
</I>><i> package we obsolete by task-obsolete
</I>><i> e.g. java-1.6.0-sun*, <A HREF="https://bugs.mageia.org/show_bug.cgi?id=3101">https://bugs.mageia.org/show_bug.cgi?id=3101</A>
</I>><i>
</I>><i> - README."nameDeprecatedPackage".deprecated.urpmi to inform about
</I>><i> package that we considere as deprecated, but we have no reason (no
</I>><i> vulnerability, security, ...) to force uninstallation (task-deprecated?).
</I>
I don't understand the need for this one, isn't this just the same as
README.urpmi?
