9	comimpl.xsl:
10	XSLT stylesheet that generates COM C++ classes implementing
11	interfaces described in VirtualBox.xidl.
12	For now we generate implementation for events, as they are
13	rather trivial container classes for their read-only attributes.
14	Further extension to other interfaces is possible and anticipated.
