[-- Attachment #1.1: Type: text/plain, Size: 502 bytes --]

All,
I am about to release udev-186-r1, which will move everything currently
in /lib/udev to /usr/lib/udev.

For packages that install udev rules in ${FILESDIR}, we need an eclass
that tests the version of udev installed on the user's system and
installs the udev rules in the proper place. I'm not sure how many
packages do this, so if it is a very small number of packages, it may
not be worth the eclass. It would be good to discuss that as well as
reviewing the proposed eclass.

Thanks,

William

# @BLURB: helper functions to install udev rules
# @DESCRIPTION:
# This eclass provides a set of functions to install udev rules.
# With versions of udev prior to 186, udev rules for extra packages were
# installed in /lib/udev/rules.d, but with newer versions they are installed in
# /usr/lib/udev/rules.d.
# @EXAMPLE:
#
# @CODE
# inherit udev-rules
#
# src_install() {
#     udev_dorules "${FILESDIR}"/foo.rules "${FILESDIR}"/bar.rules
#     udev_newrules "${FILESDIR}"/old.rules.name baz.rules
# }
# @CODE

	0|1|2|3|4) ;;
	*) die "${ECLASS}.eclass API in EAPI ${EAPI} not yet established."
