DOC_CONTENTS="\n
Please add users to the \"vboxguest\" group so they can\n
benefit from seamless mode, auto-resize and clipboard.\n
\n
The vboxsf group has been added to make automount services work.\n
These services are part of the shared folders support.\n
\n
Please add:\n
	/etc/init.d/virtualbox-guest-additions\n
to the default runlevel in order to start\n
needed services.\n
\n
An autostart .desktop file has been installed to start\n
VBoxClient in desktop sessions.\n
\n
You can mount shared folders with:\n
	mount -t vboxsf <shared_folder_name> <mount_point>\n
\n
Warning:\n
	this ebuild is only needed if you are running gentoo\n
	inside a VirtualBox Virtual Machine, you don't need\n
	it to run VirtualBox itself.\n
\n"
