+		Chapter 16: Function return values and names
+
+Functions can return values of many different kinds, and one of the
+most common is a value indicating whether the function succeeded or
+failed.  Such a value can be represented as an error-code integer
+(-Exxx = failure, 0 = success) or a "succeeded" boolean (0 = failure,
+non-zero = success).
+
+Mixing up these two sorts of representations is a fertile source of
+difficult-to-find bugs.  If the C language included a strong distinction
+between integers and booleans then the compiler would find these mistakes
+for us... but it doesn't.  To help prevent such bugs, always follow this
+convention:
+
+	If the name of a function is an action or an imperative command,
+	the function should return an error-code integer.  If the name
+	is a predicate, the function should return a "succeeded" boolean.
+
+For example, "add work" is a command, and the add_work() function returns 0
+for success or -EBUSY for failure.  In the same way, "PCI device present" is
+a predicate, and the pci_dev_present() function returns 1 if it succeeds in
+finding a matching device or 0 if it doesn't.
+
+All EXPORTed functions must respect this convention, and so should all
+public functions.  Private (static) functions need not, but it is
+recommended that they do.
+
+Functions whose return value is the actual result of a computation, rather
+than an indication of whether the computation succeeded, are not subject to
+this rule.  Generally they indicate failure by returning some out-of-range
+result.  Typical examples would be functions that return pointers; they use
+NULL or the ERR_PTR mechanism to report failure.

+Managing bug reports
+--------------------
+
+One of the best ways to put into practice your hacking skills is by fixing
+bugs reported by other people. Not only you will help to make the kernel

+1. Introduction
 ~~~~~~~~~~~~~~~
 This document describes how to use force feedback devices under Linux. The
 goal is not to support these devices as if they were simple input-only devices
 (as it is already the case), but to really enable the rendering of force
 effects.
-At the moment, only I-Force devices are supported, and not officially. That
-means I had to find out how the protocol works on my own. Of course, the
-information I managed to grasp is far from being complete, and I can not
-guarranty that this driver will work for you.
-This document only describes the force feedback part of the driver for I-Force
-devices. Please read joystick.txt before reading further this document.

 2. Instructions to the user
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Here are instructions on how to compile and use the driver. In fact, this
-driver is the normal iforce, input and evdev drivers written by Vojtech
-Pavlik, plus additions to support force feedback.
+To enable force feedback, you have to:
+
+1. have your kernel configured with evdev and a driver that supports your
+   device.
+2. make sure evdev module is loaded and /dev/input/event* device files are
+   created.
 
 Before you start, let me WARN you that some devices shake violently during the
 initialisation phase. This happens for example with my "AVB Top Shot Pegasus".
 To stop this annoying behaviour, move you joystick to its limits. Anyway, you
-should keep a hand on your device, in order to avoid it to brake down if
+should keep a hand on your device, in order to avoid it to break down if
 something goes wrong.
 
-At the kernel's compilation:
-	- Enable IForce/Serial
-	- Enable Event interface
-
-Compile the modules, install them.
-
-You also need inputattach.
-
-You then need to insert the modules into the following order:
-% modprobe joydev
-% modprobe serport		# Only for serial
-% modprobe iforce
-% modprobe evdev
-% ./inputattach -ifor $2 &	# Only for serial
-If you are using USB, you don't need the inputattach step.
-
-Please check that you have all the /dev/input entries needed:
-cd /dev
-rm js*
-mkdir input
-mknod input/js0 c 13 0
-mknod input/js1 c 13 1
-mknod input/js2 c 13 2
-mknod input/js3 c 13 3
-ln -s input/js0 js0
-ln -s input/js1 js1
-ln -s input/js2 js2
-ln -s input/js3 js3

-mknod input/event0 c 13 64
-mknod input/event1 c 13 65
-mknod input/event2 c 13 66

-BSD Secure Levels Linux Security Module
-Michael A. Halcrow <mike@halcrow.us>

-Introduction
-
-Under the BSD Secure Levels security model, sets of policies are
-associated with levels. Levels range from -1 to 2, with -1 being the
-weakest and 2 being the strongest. These security policies are
-enforced at the kernel level, so not even the superuser is able to
-disable or circumvent them. This hardens the machine against attackers
-who gain root access to the system.
-
-
-Levels and Policies
-
-Level -1 (Permanently Insecure):
- - Cannot increase the secure level
-
-Level 0 (Insecure):
- - Cannot ptrace the init process
-
-Level 1 (Default):
- - /dev/mem and /dev/kmem are read-only
- - IMMUTABLE and APPEND extended attributes, if set, may not be unset
- - Cannot load or unload kernel modules
- - Cannot write directly to a mounted block device
- - Cannot perform raw I/O operations
- - Cannot perform network administrative tasks
- - Cannot setuid any file
-
-Level 2 (Secure):
- - Cannot decrement the system time
- - Cannot write to any block device, whether mounted or not
- - Cannot unmount any mounted filesystems
-
-
-Compilation
-
-To compile the BSD Secure Levels LSM, seclvl.ko, enable the
-SECURITY_SECLVL configuration option.  This is found under Security
-options -> BSD Secure Levels in the kernel configuration menu.
-
-
-Basic Usage
-
-Once the machine is in a running state, with all the necessary modules
-loaded and all the filesystems mounted, you can load the seclvl.ko
-module:
-
-# insmod seclvl.ko
-
-The module defaults to secure level 1, except when compiled directly
-into the kernel, in which case it defaults to secure level 0. To raise
-the secure level to 2, the administrator writes ``2'' to the
-seclvl/seclvl file under the sysfs mount point (assumed to be /sys in
-these examples):
-
-# echo -n "2" > /sys/seclvl/seclvl
-
-Alternatively, you can initialize the module at secure level 2 with
-the initlvl module parameter:
-
-# insmod seclvl.ko initlvl=2
-
-At this point, it is impossible to remove the module or reduce the
-secure level.  If the administrator wishes to have the option of doing
-so, he must provide a module parameter, sha1_passwd, that specifies
-the SHA1 hash of the password that can be used to reduce the secure
-level to 0.
-
-To generate this SHA1 hash, the administrator can use OpenSSL:
-
-# echo -n "boogabooga" | openssl sha1
-abeda4e0f33defa51741217592bf595efb8d289c
-
-In order to use password-instigated secure level reduction, the SHA1
-crypto module must be loaded or compiled into the kernel:
-
-# insmod sha1.ko
-
-The administrator can then insmod the seclvl module, including the
-SHA1 hash of the password:
-
-# insmod seclvl.ko
-         sha1_passwd=abeda4e0f33defa51741217592bf595efb8d289c
-
-To reduce the secure level, write the password to seclvl/passwd under
-your sysfs mount point:
-
-# echo -n "boogabooga" > /sys/seclvl/passwd
-
-The September 2004 edition of Sys Admin Magazine has an article about
-the BSD Secure Levels LSM.  I encourage you to refer to that article
-for a more in-depth treatment of this security module:

+The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
+format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
+for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
+be more accurate.
+
+The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
+four pixels.
+
+The data is encoded as two macroblock planes, the first containing the Y
+values, the second containing UV macroblocks.
+
+The Y plane is divided into blocks of 16x16 pixels from left to right
+and from top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block, the
+second 16 bytes are the second line of the top-left block, etc. After
+transmitting this block the first line of the block on the right to the
+first block is transmitted, etc.
+
+The UV plane is divided into blocks of 16x8 UV values going from left
+to right, top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block and
+contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
+second line of 8 UV pairs of the top-left block, etc. After transmitting
+this block the first line of the block on the right to the first block is
+transmitted, etc.
+
+The code below is given as an example on how to convert HM12 to separate
+Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
+
+The width of a frame is always 720 pixels, regardless of the actual specified

+Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
+=========================================================
+
+This document describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
+embedded in an MPEG-2 program stream. This format is in part dictated by some
+hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
+chips), in particular a maximum size for the VBI data. Anything longer is cut
+off when the MPEG stream is played back through the cx23415.
+
+The advantage of this format is it is very compact and that all VBI data for
+all lines can be stored while still fitting within the maximum allowed size.
+
+The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
+4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
+header and a 42 bytes payload each. Anything beyond this limit is cut off by
+the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
+for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
+signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
+If all lines are used, then there is no longer room for the bitmask. To solve this
+two different magic numbers were introduced:
+
+'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
+unsigned long denote which lines of the first field are captured. Bits 18-31 of
+the first unsigned long and bits 0-3 of the second unsigned long are used for the
+second field.
+
+'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
+implies that the bitmasks are 0xffffffff and 0xf.
+
+After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
+captured VBI lines start:
+
+For each line the least significant 4 bits of the first byte contain the data type.
+Possible values are shown in the table below. The payload is in the following 42
+bytes.
+
+Here is the list of possible data types:
+
+#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
+#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
+#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
+#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

-59 Temple Place - Suite 330, Boston, MA  02111-1307, 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 Library 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. 
-
-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 an idea of what it does.
-Copyright (C) yyyy  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., 59 
-Temple Place - Suite 330, Boston, MA  02111-1307, 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 Library General Public 
-License instead of this License.

-		    GNU GENERAL PUBLIC LICENSE
-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330, Boston, MA 02111-1307, 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 Library 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
-
-	Appendix: 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) 19yy  <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., 59 Temple Place - Suite 330, Boston, MA 02111-1307, 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) 19yy 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 Library General
-Public License instead of this License.
