commit bf2a2622ef34d2140cff7d08e393fbed0154072f
Author: Steve Frécinaux <code istique net>
Date: Wed May 19 12:22:21 2010 +0200
Introduce PeasExtensionSet.
This is a way to handle all the plugins at once, for some specialized
use. Especially, "PeasActivatable" extensions fit fine with this new
object.
A way to check that called functions don't expect OUT or INOUT args is
currently missing.
