[OpenIndiana-discuss] remove orphaned packages and leaves?

[Paolo Vincenzo Olivo]

Hi,
 Does IPS pkg provides an autoremove function or similar? Is there any
 way to quickly remove orphaned packages (automatically installed as
 dependencies and no longer required) and leaf packages (manually
 installed but  not serving as dependency for any package). I thoroughly
 went through pkg man page, but apparently found nothing useful under
 `pkg uninstall` section; on the other hand `pkg avoid` seems not suited
 to accomplish this task, requiring one to know an unneeded dependency
 package name beforehand
 Any hint would be greatly appreciated,

 Yours sincerely,
 Vincenzo
