### History:

## 0.4  2022-12-14 23:45Z
##      (LH_CONF): New variable.
##      (MQ_CONF): Likewise.
##      (lh-start): Use $(START_STOP_DAEMON) --chdir=. option,
##      as we rely on relative filenames throughout.
##      (mq-start): Likewise.
##      (pg-mkdb): Fixed the use of the :@@@ modifier.
##      (tests): Use :Q variable modifier.

## 0.3  2022-12-14 07:05:47Z
##      (sfn.xvg6FXe3BGdhHIUufCU5oEjzLWb76IW7dLU1agVuRRA.mk)
##      (default): Depend on checks (was: pg-ck.)
##      (checks): New non-file target depending on pg-ck,
##      mq-ck, lh-ck.
##      (MOSQUITTO): New variable.
##      (LIGHTTPD): Likewise.
##      (CURL): Likewise.
##      (CURL_FLAGS): Likewise.
##      (MOSQUITTO_PUB): Likewise.
##      (START_STOP_DAEMON): Likewise.
##      (LH_PID): Likewise.
##      (LH_URI): Likewise.
##      (MQ_PID): Likewise.
##      (MQ_SOCK): Likewise.
##      (lh-ck): New non-file target.
##      (lh-start): Likewise.
##      (lh-stop): Likewise.
##      (mq-ck): Likewise.
##      (mq-start): Likewise.
##      (mq-stop): Likewise.
##      (pg-ck): Check if the process is still running first.
##      (pg-mkdb): Also depend on sql/logger.sql sql/report.sql,
##      and pass them to $(PSQL) -f.
##      (pg-mkdb): Use :Q variable modifier whenever possible.
##      ($(PG_PID)): Likewise.
##      ($(PG_DIR)): Likewise.
##      (tests): Simplified.

## 0.2  2022-11-25 17:30:50Z
##      (sfn._jx003OeN6HUAnU5q2EMaYXfmVTqLg36UqSIcLTxFWg.mk)
##      Added a short usage example to Commentary:.
##      (PERL): New variable.
##      (TESTS): Likewise.
##      (tests): New target.
##      (.PHONY): Add tests.
##      (PGDATABASE): Export variable.
##      (PGUSER): Likewise.
##      (PGHOST): Likewise.
##      (pg-mkdb): Fixed: use -d option to $(PSQL) (was: -D.)
##      Fixed: do not try to ensure the database is running by
##      executing an empty command (was: exitting successfully if so.)
##      Also create $(PGUSER) role and, under that role, execute
##      sql/create.sql, on which we now depend as well.
##      ($(PG_DIR)): Also initialize pg_ident.conf with a sole unix
##      map allowing $(USER) to connect as both $(PGSUPERUSER) and
##      $(PGUSER).  Use local map=unix in pg_hba.conf (was: trust.)

## 0.1  2022-11-23 08:55:15Z
##      (sfn.RaNqOh7pX10CBNADa8NW1I5mCQW8GPk929X-LCkLcbo.mk)
