# @BLURB: helper functions to install systemd units
# @DESCRIPTION:
# This eclass provides a set of functions to install unit files for
# sys-apps/systemd within ebuilds.
# @EXAMPLE:
#
# @CODE
# inherit autotools-utils systemd
#
# src_configure() {
# local myeconfargs=(
# --enable-foo
# --disable-bar
# )
#
# systemd_to_myeconfargs
# autotools-utils_src_configure
# }
# @CODE

# @DESCRIPTION:
# Get unprefixed unitdir.

# This function always succeeds, even if systemd is not installed.

# and non-fatal in earlier EAPIs.

# @DESCRIPTION:
# Output '--with-systemdsystemunitdir' as expected by systemd-aware configure
# scripts. This function always succeeds. Its output may be quoted in order
# to preserve whitespace in paths. systemd_to_myeconfargs() is preferred over
# this function.
#
# If upstream does use invalid configure option to handle installing systemd
# units (e.g. `--with-systemdunitdir'), you can pass the 'suffix' as an optional
# argument to this function (`$(systemd_with_unitdir systemdunitdir)'). Please
# remember to report a bug upstream as well.

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