8# information about where certain interfaces are located.

10# NOTE: If you use this, be sure you use the need_* call after you have
11# defined DEPEND and RDEPEND. Also note that you can not rely on the
12# automatic RDEPEND=DEPEND that portage does if you use this eclass.
13# See bug 107127 for more information.
