8 # @BLURB: helper functions to install systemd units
9 # @DESCRIPTION:
10 # This eclass provides a set of functions to install unit files for
11 # sys-apps/systemd within ebuilds.
12 # @EXAMPLE:
13 #
14 # @CODE
15 # inherit autotools-utils systemd
16 #
17 # src_configure() {
18 # local myeconfargs=(
19 # --enable-foo
20 # --disable-bar
21 # )
22 #
23 # systemd_to_myeconfargs
24 # autotools-utils_src_configure
25 # }
26 # @CODE
