+# Adapted log_prop file for clkctl. All runs of clkctl will add logging to 
+# an existing Rolling logfile, instead of creating a new one each run.
+# As clkctl is often called during observations, this would create too many
+# instances of clkctl.log files, and many older files were overwritten which
+# made debugging or finding out what happened in case of a problem impossible. 
+#
+# setup the right levels for logging and tracing
+#
+# Note: In production you don't want to loose any information so a daily rolling-file
+#       is used and tracing is switched off.
+#       For debugging purposes the daily rolling-file becomes too large so a size-based
+#       rolling file is used and tracing is switched on.
+# 
+# Please do not change the logger lines below, only comment them in or out.
+
+# For PRODUCTION:
+# - Select the appropriate log-level for the rootLogger (DEBUG or INFO)
+# - Leave the TRC logger on DEBUG,DUMP
+# - Comment out the rootLogger and the TRC logger in the TEST section of this file
+#log4cplus.rootLogger=DEBUG, DAILYFILE
+log4cplus.rootLogger=INFO, ROLFILE

+# - Comment out the rootLogger and the TRC logger in the PRODUCTION section of this file
