27 # Check the availability of systemd. If the systemd (or the old systemd-daemon)
28 # library is found, we define HAVE_SYSTEMD_SD_DAEMON_H to 1. We then also set
29 # the output variables SYSTEMDCPPFLAGS, SYSTEMDLDFLAGS, and SYSTEMDLIBS to
30 # appropriate values. (Why are there no underscores in these variable names?
31 # Because Automake treats names like "foo_CPPFLAGS" specially.)
