-		    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
-nxauth \- NoMachine X authority file utility
-.SH SYNOPSIS
-.B nxauth
-[ \fB\-f\fP \fIauthfile\fP ] [ \fB\-vqib\fP ] [ \fIcommand arg ...\fP ]
-.SH DESCRIPTION
-.PP
-The \fInxauth\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 \fInxauth\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 \fInxauth\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 \fInxauth\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,
-\fInxauth\fP will use the file specified by the nxauthORITY environment variable
-or \fI\.Xauthority\fP in the user's home directory.
-.TP 8
-.B \-q
-This option indicates that \fInxauth\fP should operate quietly and not print
-unsolicited status messages.  This is the default if an \fInxauth\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 \fInxauth\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 \fInxauth\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 \fInxauth\fP should ignore any authority file
-locks.  Normally, \fInxauth\fP will refuse to read or edit any authority files
-that have been locked by other programs (usually \fIxdm\fP or another 
-\fInxauth\fP).
-.TP 8
-.B \-b
-This option indicates that \fInxauth\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 \fInxauth\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 \fInxauth\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 \fInxauth\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
-        %  nxauth extract \- $DISPLAY | rsh otherhost nxauth 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
-	%  nxauth generate :0 .
-.fi
-.SH ENVIRONMENT
-This \fInxauth\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.
