+# Edit this file to introduce tasks to be run by cron.

+# Each task to run has to be defined through a single line

+# and what command to run for the task
+#
+# To define the time you can provide concrete values for
+# minute (m), hour (h), day of month (dom), month (mon),
+# and day of week (dow) or use '*' in these fields (for 'any').
+#
+# Notice that tasks will be started based on the cron's system

+#
+# Output of the crontab jobs (including errors) is sent through
+# email to the user the crontab file belongs to (unless redirected).
