.SH NAME
-cron \- daemon to execute scheduled commands (ISC Cron V4.1)
+cron \- daemon to execute scheduled commands (cronie V1.2)
.SH SYNOPSIS
.B cron
.RB [ -n " | " -p " | " -m \fP\fI<mail command>\fP\fB ]
commands, any output is mailed to the owner of the crontab (or to the user
named in the MAILTO environment variable in the crontab, if such exists).
.PP
-Additionally,
-.I cron
-checks each minute to see if its spool directory's modtime (or the modtime
-on
-.IR /etc/crontab )
-has changed, and if it has,
-.I cron
-will then examine the modtime on all crontabs and reload those which have
-changed. Thus
+There are two ways, how the changes are checked in crontables. The first
+is checking the modtime of file and the other is using inotify support.
+You can find out which of them are you using, if you check
+.I /var/log/cron
+where is (or isn't) inotify mentioned after start of daemon. The inotify support
+is watching for changes in all crontables and touch the disk only in case
+that something was changed.
+.PP
+In other case
.I cron
-need not be restarted whenever a crontab file is modified. Note that the
+checks each minute to see if its crontables modtime have changes and reload
+those which have changes. There is no need to restart cron after some of the
+crontable is modified. This option is used also when inotify couldn't be initialized.
+.PP
+.I Cron
+is checking those files or directories:
+.IR /etc/crontab
+system crontab is usually for running daily, weekly, monthly jobs.
+.BR
+.IR /etc/cron.d/
+where are system cronjobs stored for different users.
+.BR
+.IR /var/spool/cron
+that's mean spool directory for user crontables.
+
+Note that the
.BR crontab (1)
command updates the modtime of the spool directory whenever it changes a
crontab.
