Paul Vixie's cron, version 3.0. Munged into bmake format. If this goes
well, expect our two seperate directories for cron and crontab to go away shortly. Submitted by: jkh

+.SH NAME
+crontab \- maintain crontab files for individual users (V3)
+.SH SYNOPSIS
+crontab [ -u user ] file
+.br
+crontab [ -u user ] { -l | -r | -e }
+.SH DESCRIPTION
+.I Crontab
+is the program used to install, deinstall or list the tables
+used to drive the
+.IR cron (8)
+daemon in Vixie Cron. Each user can have their own crontab, and though
+these are files in /var, they are not intended to be edited directly.
+.PP
+If the
+.I allow
+file exists, then you must be listed therein in order to be allowed to use
+this command. If the
+.I allow
+file does not exist but the
+.I deny
+file does exist, then you must \fBnot\fR be listed in the
+.I deny
+file in order to use this command. If neither of these files exists, then
+depending on site-dependent configuration parameters, only the super user
+will be allowed to use this command, or all users will be able to use this
+command.
+.PP
+If the
+.I -u
+option is given, it specifies the name of the user whose crontab is to be
+tweaked. If this option is not given,
+.I crontab
+examines "your" crontab, i.e., the crontab of the person executing the
+command. Note that
+.IR su (8)
+can confuse
+.I crontab
+and that if you are running inside of
+.IR su (8)
+you should always use the
+.I -u
+option for safety's sake.
+.PP
+The first form of this command is used to install a new crontab from some
+named file or standard input if the pseudo-filename ``-'' is given.
+.PP
+The
+.I -l
+option causes the current crontab to be displayed on standard output.
+.PP
+The
+.I -r
+option causes the current crontab to be removed.
+.PP
+The
+.I -e
+option is used to edit the current crontab using the editor specified by
+the \s-1VISUAL\s+1 or \s-1EDITOR\s+1 environment variables. After you exit
+from the editor, the modified crontab will be installed automatically.
+.SH "SEE ALSO"
+crontab(5), cron(8)
+.SH FILES
+.nf
+/var/cron/allow
+/var/cron/deny
+.fi
+.SH STANDARDS
+The
+.I crontab
+command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax
+differs from previous versions of Vixie Cron, as well as from the classic
+SVR3 syntax.
+.SH DIAGNOSTICS
+A fairly informative usage message appears if you run it with a bad command
+line.
