     34 This is a version of 'cron' that is known to run on most systems.  It
     35 is functionally based on the SysV cron, which means that each user can have
     36 their own crontab file (all crontab files are stored in a read-protected
     37 directory, usually /var/cron/tabs).  No direct support is provided for
     38 'at'; you can continue to run 'atrun' from the crontab as you have been
     39 doing.  If you don't have atrun (i.e., System V) you are in trouble.
     40 
     41 A messages is logged each time a command is executed; also, the files
     42 "allow" and "deny" in /var/cron can be used to control access to the
     43 "crontab" command (which installs crontabs).  It hasn't been tested on
     44 SysV, although some effort has gone into making the port an easy one.
     45 
     46 To use this: Sorry, folks, there is no cutesy 'Configure' script.  You'll
     47 have to go edit a couple of files... So, here's the checklist:
     48 
     49 	Read all the FEATURES, INSTALL, and CONVERSION files
     50 	Edit config.h
     51 	Edit Makefile
     52 		(both of these files have instructions inside; note that
     53 		 some things in config.h are definable in Makefile and are
     54 		 therefore surrounded by #ifndef...#endif)
     55 	'make'
     56 	'su' and 'make install'
     57 		(you may have to install the man pages by hand)
     58 	kill your existing cron process
     59 		(actually you can run your existing cron if you want, but why?)
     60 	build new crontabs using /usr/lib/{crontab,crontab.local}
     61 		(either put them all in "root"'s crontab, or divide it up
     62 		 and rip out all the 'su' commands, collapse the lengthy
     63 		 lists into ranges with steps -- basically, this step is
     64 		 as much work as you want to make it)
     65 	start up the new cron
     66 		(must be done as root)
     67 	watch it. test it with 'crontab -r' and watch the daemon track your
     68 		changes.
     69 	if you like it, change your /etc/{rc,rc.local} to use it instead of
     70 		the old one.
