+This is the top level of the FreeBSD source directory.  This file

+
+For copyright information, please see the file COPYRIGHT in this
+directory (additional copyright information also exists for some
+sources in this tree - please see the specific source directories for
+more information).
+
+The Makefile in this directory supports a number of targets for
+building components (or all) of the FreeBSD source tree, the most
+commonly used one being ``world'', which rebuilds and installs
+everything in the FreeBSD system from the source tree except the
+kernel and the contents of /etc.  Please see the top of the Makefile
+in this directory for more information on the standard build targets
+and compile-time flags.
+
+Building a kernel with config(8) is a somewhat more involved process,
+documentation for which can be found at:
+   http://www.freebsd.org/handbook/kernelconfig.html
+And in the config(8) man page.
+
+The sample kernel configuration files reside in the sys/i386/conf
+sub-directory (assuming that you've installed the kernel sources), the
+file named GENERIC being the one used to build your initial installation
+kernel.  The file LINT contains entries for all possible devices, not
+just those commonly used, and is meant more as a general reference
+than an actual kernel configuration file (a kernel built from it
+wouldn't even run).
+
+
+Source Roadmap:
+---------------
+bin		System/User commands.
+
+contrib		Packages contributed by 3rd parties.
+
+crypto		Export controlled stuff (see crypto/README).
+
+etc		Template files for /etc
+
+games		Amusements.
+
+gnu		Various commands and libraries under the GNU Public License.
+		Please see gnu/COPYING* for more information.
+
+include		System include files.
+
+kerberosIV	Kerberos package - also export controlled.
+
+lib		System libraries.
+
+libexec		System daemons.
+
+lkm		Loadable Kernel Modules.
+
+release		Release building Makefile & associated tools.
+
+sbin		System commands.
+
+secure		DES and DES-related utilities - NOT FOR EXPORT!
+
+share		Shared resources.
+
+sys		Kernel sources.
+
+tools		Utilities for regression testing and miscellaneous tasks.
+
+usr.bin		User commands.
+
+usr.sbin	System administration commands.

-.Nm chflags
-.Oo
-.Fl R
-.Op Fl H | Fl L | Fl P
-.Oc
-.Ar flags
-.Ar file ...
-.Sh DESCRIPTION
-The
-.Nm chflags
-utility modifies the file flags of the listed files
-as specified by the
-.Ar flags
-operand.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl H
-If the
-.Fl R
-option is specified, symbolic links on the command line are followed.
-(Symbolic links encountered in the tree traversal are not followed.)
-.It Fl L
-If the
-.Fl R
-option is specified, all symbolic links are followed.
-.It Fl P
-If the
-.Fl R
-option is specified, no symbolic links are followed.
-.It Fl R
-Change the file flags for the file hierarchies rooted
-in the files instead of just the files themselves.
-.El
-.Pp
-Flags are a comma separated list of keywords.
-The following keywords are currently defined:
-.Bd -literal -offset indent compact
-arch	set the archived flag (super-user only)
-dump	set the dump flag
-sappnd	set the system append-only flag (super-user only)
-schg	set the system immutable flag (super-user only)
-uappnd	set the user append-only flag (owner or super-user only)
-uchg	set the user immutable flag (owner or super-user only)
-archived, sappend, schange, simmutable, uappend, uchange, uimmutable
-	aliases for the above
-.Ed
-.Pp
-Putting the letters
-.Dq no
-before an option causes the flag to be turned off.
-For example:
-.Bd -literal -offset indent compact
-nodump	the file should never be dumped
-.Ed
-.Pp
-Symbolic links do not have flags, so unless the
-.Fl H
-or
-.Fl L
-option is set,
-.Nm chflags
-on a symbolic link always succeeds and has no effect.
-The
-.Fl H ,
-.Fl L
-and
-.Fl P
-options are ignored unless the
-.Fl R
-option is specified.
-In addition, these options override each other and the
-command's actions are determined by the last one specified.
-.Pp
-The
-.Nm chflags
-utility exits 0 on success, and >0 if an error occurs.

+.Nd medium changer control utility
+.Sh SYNOPSIS
+.Nm chio
+.Op Fl f Ar changer
+.Ar command
+.Ar arg1
+.Ar arg2
+.Oo
+.Ar arg3 Oo ...
+.Oc
+.Oc
+.Sh DESCRIPTION
+.Nm Chio
+is used to control the operation of medium changers, such as those found
+in tape and optical disk jukeboxes.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl f Ar changer
+Use the device
+.Pa changer
+rather than the default device
+.Pa /dev/ch0 .
+.El
+.Pp
+The default changer may be overridden by setting the environment variable
+.Ev CHANGER
+to the desired changer device.
+.Pp
+A medium changer apparatus is made up of
+.Em elements .
+There are four element types:
+.Em picker
+(medium transport),
+.Em slot
+(storage),
+.Em portal
+(import/export), and
+.Em drive
+(data transfer).  In this command description, the shorthand
+.Em ET
+will be used to represent an element type, and
+.Em EU
+will be used to represent an element unit.  For example, to represent
+the first robotic arm in the changer, the
+.Em ET
+would be
+.Dq picker
+and the
+.Em EU
+would be
+.Dq 0 .
+.Pp
+.Sh SUPPORTED COMMANDS
+.Bl -tag -width indent
+.It Xo Nm chio move
+.Ar <from ET> <from EU> <to ET> <to EU>
+.Op Ar inv
+.Xc
+Move the media unit from
+.Pa <from ET/EU>
+to
+.Pa <to ET/EU> .
+If the optional modifier
+.Pa inv
+is specified, the media unit will be inverted before insertion.
+.It Xo Nm chio exchange
+.Ar <src ET> <src EU> <dst1 ET> <dst1 EU>
+.Op Ar <dst2 ET> <dst2 ET>
+.Op Ar inv1
+.Op Ar inv2
+.Xc
+Perform a media unit exchange operation.  The media unit in
+.Pa <src ET/EU>
+is moved to
+.Pa <dst1 ET/EU>
+and the media unit previously in
+.Pa <dst1 ET/EU>
+is moved to
+.Pa <dst2 ET/EU> .
+In the case of a simple exchange,
+.Pa <dst2 ET/EU>
+is omitted and the values
+.Pa <src ET/EU>
+are used in their place.
+The optional modifiers
+.Pa inv1
+and
+.Pa inv2
+specify whether the media units are to be inverted before insertion into
+.Pa <dst1 ET/EU>
+and
+.Pa <dst2 ET/EU>
+respectively.
+.Pp
+Note that not all medium changers support the
+.Nm exchange
+operation; The changer must have multiple free pickers or emulate
+multiple free pickers with transient storage.
+.It Xo Nm chio position
+.Ar <to ET> <to EU>
+.Op Ar inv
+.Xc
+Position the picker in front of the element described by
+.Pa <to ET/EU> .
+If the optional modifier
+.Pa inv
+is specified, the media unit will be inverted before insertion.
+.Pp
+Note that not all changers behave as expected when issued this command.
+.It Nm chio params
+Report the number of slots, drives, pickers, and portals in the changer,
+and which picker unit the changer is currently configured to use.
+.It Nm chio getpicker
+Report which picker unit the changer is currently configured to use.
+.It Xo Nm chio setpicker
+.Ar <unit>
+.Xc
+Configure the changer to use picker
+.Pa <unit> .
+.It Xo Nm chio status
+.Op Ar <type>
+.Xc
+Report the status of all elements in the changer.  If
+.Pa <type>
+is specified, report the status of all elements of type
+.Pa <type> .
+.El
+.Pp
+The status bits are defined as follows:
+.Bl -tag -width indent
+.It FULL
+Element contains a media unit.
+.It IMPEXP
+Media was deposited into element by an outside human operator.
+.It EXCEPT
+Element is in an abnormal state.
+.It ACCESS
+Media in this element is accessible by a picker.
+.It EXENAB
+Element supports passing media (exporting) to an outside human operator.
+.It INENAB
+Element supports receiving media (importing) from an outside human operator.
+.El
+.Sh EXAMPLES
+.Bl -tag -width indent
+.It Nm chio move slot 3 drive 0
+Move the media in slot 3 (fourth slot) to drive 0 (first drive).
+.It Nm chio setpicker 2
+Configure the changer to use picker 2 (third picker) for operations.
