Thanks for your review.<br>
I guess Cyril will prefer .needs_cmds, as it can be parsed - metadata project:<br>

I put it there because some command might be run just under some condition (not<br>
always), thus not suitable for .needs_cmds, but still nice to have reliable<br>
check. But maybe I'm wrong.<br></blockquote><div><span class="gmail_default" style="font-size:small"><br></span></div><div><span class="gmail_default" style="font-size:small">+1 you're right, I believe that is safer and choosable for the test.</span></div></div><div><br></div>-- <br><div dir="ltr"><div dir="ltr"><div>Regards,<br></div><div>Li Wang<br></div></div></div></div>
