+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+.TH XAUTH 1 __xorgversion__
+.SH NAME
+xauth \- X authority file utility
+.SH SYNOPSIS
+.B xauth
+[ \fB\-f\fP \fIauthfile\fP ] [ \fB\-vqib\fP ] [ \fIcommand arg ...\fP ]
+.SH DESCRIPTION
+.PP
+The \fIxauth\fP program is used to edit and display the authorization
+information used in connecting to the X server. This program is usually
+used to extract authorization records from one machine and merge them in on
+another (as is the case when using remote logins or granting access to
+other users). Commands (described below) may be entered interactively,
+on the \fIxauth\fP command line, or in scripts. Note that this program
+does \fBnot\fP contact the X server except when the generate command is used.
+Normally \fIxauth\fP is not used to create the authority file entry in
+the first place; \fIxdm\fP does that.
+.SH OPTIONS
+The following options may be used with \fIxauth\fP. They may be given
+individually (e.g., \fI\-q \-i\|\fP) or may combined (e.g., \fI\-qi\|\fP).
+.TP 8
+.B "\-f \fIauthfile\fP"
+This option specifies the name of the authority file to use. By default,
+\fIxauth\fP will use the file specified by the XAUTHORITY environment variable
+or \fI\.Xauthority\fP in the user's home directory.
+.TP 8
+.B \-q
+This option indicates that \fIxauth\fP should operate quietly and not print
+unsolicited status messages. This is the default if an \fIxauth\fP command is
+is given on the command line or if the standard output is not directed to a
+terminal.
+.TP 8
+.B \-v
+This option indicates that \fIxauth\fP should operate verbosely and print
+status messages indicating the results of various operations (e.g., how many
+records have been read in or written out). This is the default if \fIxauth\fP
+is reading commands from its standard input and its standard output is
+directed to a terminal.
+.TP 8
+.B \-i
+This option indicates that \fIxauth\fP should ignore any authority file
+locks. Normally, \fIxauth\fP will refuse to read or edit any authority files
+that have been locked by other programs (usually \fIxdm\fP or another
+\fIxauth\fP).
+.TP 8
+.B \-b
+This option indicates that \fIxauth\fP should attempt to break any authority
+file locks before proceeding. Use this option only to clean up stale locks.
+.SH COMMANDS
+The following commands may be used to manipulate authority files:
+.TP 8
+.B "add \fIdisplayname protocolname hexkey"
+An authorization entry for the indicated display using the given protocol
+and key data is added to the authorization file. The data is specified as
+an even-lengthed string of hexadecimal digits, each pair representing
+one octet. The first digit of each pair gives the most significant 4 bits
+of the octet, and the second digit of the pair gives the least significant 4
+bits. For example, a 32 character hexkey would represent a 128-bit value.
+A protocol name consisting of just a
+single period is treated as an abbreviation for \fIMIT-MAGIC-COOKIE-1\fP.
+
+.TP 8
+.B "generate \fIdisplayname protocolname\fP \fR[\fPtrusted|untrusted\fR]\fP"
+.B \fR[\fPtimeout \fIseconds\fP\fR]\fP \fR[\fPgroup \fIgroup-id\fP\fR]\fP \fR[\fBdata \fIhexdata\fR]
+
+This command is similar to add. The main difference is that instead
+of requiring the user to supply the key data, it connects to the
+server specified in \fIdisplayname\fP and uses the SECURITY extension
+in order to get the key data to store in the authorization file. If
+the server cannot be contacted or if it does not support the SECURITY
+extension, the command fails. Otherwise, an authorization entry for
+the indicated display using the given protocol is added to the
+authorization file. A protocol name consisting of just a single
+period is treated as an abbreviation for \fIMIT-MAGIC-COOKIE-1\fP.
+
+If the \fBtrusted\fP option is used, clients that connect using this
+authorization will have full run of the display, as usual. If
+\fBuntrusted\fP is used, clients that connect using this authorization
+will be considered untrusted and prevented from stealing or tampering
+with data belonging to trusted clients. See the SECURITY extension
+specification for full details on the restrictions imposed on
+untrusted clients. The default is \fBuntrusted\fP.
+
+The \fBtimeout\fP option specifies how long in seconds this
+authorization will be valid. If the authorization remains unused (no
+clients are connected with it) for longer than this time period, the
+server purges the authorization, and future attempts to connect using
+it will fail. Note that the purging done by the server does \fBnot\fP
+delete the authorization entry from the authorization file. The
+default timeout is 60 seconds.
+
+The \fBgroup\fP option specifies the application group that clients
+connecting with this authorization should belong to. See the
+application group extension specification for more details. The
+default is to not belong to an application group.
+
+The \fBdata\fP option specifies data that the server should use to
+generate the authorization. Note that this is \fBnot\fP the same data
+that gets written to the authorization file. The interpretation of
+this data depends on the authorization protocol. The \fIhexdata\fP is
+in the same format as the \fIhexkey\fP described in the add command.
+The default is to send no data.
+
+.TP 8
+.B "[n]extract \fIfilename displayname..."
+Authorization entries for each of the specified displays are written to the
+indicated file. If the \fInextract\fP command is used, the entries are written
+in a numeric format suitable for non-binary transmission (such as secure
+electronic mail). The extracted entries can be read back in using the
+\fImerge\fP and \fInmerge\fP commands. If the filename consists of
+just a single dash, the entries will be written to the standard output.
+.TP 8
+.B "[n]list \fR[\fIdisplayname\fP...]"
+Authorization entries for each of the specified displays (or all if no
+displays are named) are printed on the standard output. If the \fInlist\fP
+command is used, entries will be shown in the numeric format used by
+the \fInextract\fP command; otherwise, they are shown in a textual format.
+Key data is always displayed in the hexadecimal format given in the
+description of the \fIadd\fP command.
+.TP 8
+.B "[n]merge \fR[\fIfilename\fP...]"
+Authorization entries are read from the specified files and are merged into
+the authorization database, superceding any matching existing entries. If
+the \fInmerge\fP command is used, the numeric format given in the description
+of the \fIextract\fP command is used. If a filename consists of just a single
+dash, the standard input will be read if it hasn't been read before.
+.TP 8
+.B "remove \fIdisplayname\fR..."
+Authorization entries matching the specified displays are removed from the
+authority file.
+.TP 8
+.B "source \fIfilename"
+The specified file is treated as a script containing \fIxauth\fP commands
+to execute. Blank lines and lines beginning with a sharp sign (#) are
+ignored. A single dash may be used to indicate the standard input, if it
+hasn't already been read.
+.TP 8
+.B "info"
+Information describing the authorization file, whether or not any changes
+have been made, and from where \fIxauth\fP commands are being read
+is printed on the standard output.
+.TP 8
+.B "exit"
+If any modifications have been made, the authority file is written out (if
+allowed), and the program exits. An end of file is treated as an implicit
+\fIexit\fP command.
+.TP 8
+.B "quit"
+The program exits, ignoring any modifications. This may also be accomplished
+by pressing the interrupt character.
+.TP 8
+.B "help [\fIstring\fP]"
+A description of all commands that begin with the given string (or all
+commands if no string is given) is printed on the standard output.
+.TP 8
+.B "?"
+A short list of the valid commands is printed on the standard output.
+.SH "DISPLAY NAMES"
+Display names for the \fIadd\fP, \fI[n]extract\fP, \fI[n]list\fP,
+\fI[n]merge\fP, and \fIremove\fP commands use the same format as the
+DISPLAY environment variable and the common \fI\-display\fP command line
+argument. Display-specific information (such as the screen number)
+is unnecessary and will be ignored.
+Same-machine connections (such as local-host sockets,
+shared memory, and the Internet Protocol hostname \fIlocalhost\fP) are
+referred to as \fIhostname\fP/unix:\fIdisplaynumber\fP so that
+local entries for different machines may be stored in one authority file.
+.SH EXAMPLE
+.PP
+The most common use for \fIxauth\fP is to extract the entry for the
+current display, copy it to another machine, and merge it into the
+user's authority file on the remote machine:
+.sp
+.nf
+ % xauth extract \- $DISPLAY | rsh otherhost xauth merge \-
+.fi
+.PP
+.sp
+The following command contacts the server :0 to create an
+authorization using the MIT-MAGIC-COOKIE-1 protocol. Clients that
+connect with this authorization will be untrusted.
+.nf
+ % xauth generate :0 .
+.fi
+.SH ENVIRONMENT
+This \fIxauth\fP program uses the following environment variables:
+.TP 8
+.B XAUTHORITY
+to get the name of the authority file to use if the \fI\-f\fP option isn't
+used.
+.TP 8
+.B HOME
+to get the user's home directory if XAUTHORITY isn't defined.
+.SH FILES
+.TP 8
+.I $HOME/.Xauthority
+default authority file if XAUTHORITY isn't defined.
+.SH BUGS
+.PP
+Users that have unsecure networks should take care to use encrypted
+file transfer mechanisms to copy authorization entries between machines.
+Similarly, the \fIMIT-MAGIC-COOKIE-1\fP protocol is not very useful in
+unsecure environments. Sites that are interested in additional security
+may need to use encrypted authorization mechanisms such as Kerberos.
+.PP
+Spaces are currently not allowed in the protocol name. Quoting could be
+added for the truly perverse.
