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

90 # EAPIs.

108 # scripts. This function always succeeds. Its output may be quoted in order
109 # to preserve whitespace in paths. systemd_to_myeconfargs() is preferred over
110 # this function.
111 #
112 # If upstream does use invalid configure option to handle installing systemd
113 # units (e.g. `--with-systemdunitdir'), you can pass the 'suffix' as an optional
114 # argument to this function (`$(systemd_with_unitdir systemdunitdir)'). Please
115 # remember to report a bug upstream as well.

124 # @DESCRIPTION:
125 # Add '--with-systemdsystemunitdir' as expected by systemd-aware configure
126 # scripts to the myeconfargs variable used by autotools-utils eclass. Handles
127 # quoting automatically.
