    26

		       Version 2, June 1991

    27

    28

 Copyright (C) 1989, 1991 Free Software Foundation, Inc.

    29

     51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

    30

 Everyone is permitted to copy and distribute verbatim copies

    31

 of this license document, but changing it is not allowed.

    32

    33

			    Preamble

    34

    35

  The licenses for most software are designed to take away your

    36

freedom to share and change it.  By contrast, the GNU General Public

    37

License is intended to guarantee your freedom to share and change free

    38

software--to make sure the software is free for all its users.  This

    39

General Public License applies to most of the Free Software

    40

Foundation's software and to any other program whose authors commit to

    41

using it.  (Some other Free Software Foundation software is covered by

    42

the GNU Library General Public License instead.)  You can apply it to

    43

your programs, too.

    44

    45

  When we speak of free software, we are referring to freedom, not

    46

price.  Our General Public Licenses are designed to make sure that you

    47

have the freedom to distribute copies of free software (and charge for

    48

this service if you wish), that you receive source code or can get it

    49

if you want it, that you can change the software or use pieces of it

    50

in new free programs; and that you know you can do these things.

    51

    52

  To protect your rights, we need to make restrictions that forbid

    53

anyone to deny you these rights or to ask you to surrender the rights.

    54

These restrictions translate to certain responsibilities for you if you

    55

distribute copies of the software, or if you modify it.

    56

    57

  For example, if you distribute copies of such a program, whether

    58

gratis or for a fee, you must give the recipients all the rights that

    59

you have.  You must make sure that they, too, receive or can get the

    60

source code.  And you must show them these terms so they know their

    61

rights.

    62

    63

  We protect your rights with two steps: (1) copyright the software, and

    64

(2) offer you this license which gives you legal permission to copy,

    65

distribute and/or modify the software.

    66

    67

  Also, for each author's protection and ours, we want to make certain

    68

that everyone understands that there is no warranty for this free

    69

software.  If the software is modified by someone else and passed on, we

    70

want its recipients to know that what they have is not the original, so

    71

that any problems introduced by others will not reflect on the original

    72

authors' reputations.

    73

    74

  Finally, any free program is threatened constantly by software

    75

patents.  We wish to avoid the danger that redistributors of a free

    76

program will individually obtain patent licenses, in effect making the

    77

program proprietary.  To prevent this, we have made it clear that any

    78

patent must be licensed for everyone's free use or not licensed at all.

    79

    80

  The precise terms and conditions for copying, distribution and

    81

modification follow.

    87

   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    88

    89

  0. This License applies to any program or other work which contains

    90

a notice placed by the copyright holder saying it may be distributed

    91

under the terms of this General Public License.  The "Program", below,

    92

refers to any such program or work, and a "work based on the Program"

    93

means either the Program or any derivative work under copyright law:

    94

that is to say, a work containing the Program or a portion of it,

    95

either verbatim or with modifications and/or translated into another

    96

language.  (Hereinafter, translation is included without limitation in

    97

the term "modification".)  Each licensee is addressed as "you".

    98

    99

Activities other than copying, distribution and modification are not

   100

covered by this License; they are outside its scope.  The act of

   101

running the Program is not restricted, and the output from the Program

   102

is covered only if its contents constitute a work based on the

   103

Program (independent of having been made by running the Program).

   104

Whether that is true depends on what the Program does.

   105

   106

  1. You may copy and distribute verbatim copies of the Program's

   107

source code as you receive it, in any medium, provided that you

   108

conspicuously and appropriately publish on each copy an appropriate

   109

copyright notice and disclaimer of warranty; keep intact all the

   110

notices that refer to this License and to the absence of any warranty;

   111

and give any other recipients of the Program a copy of this License

   112

along with the Program.

   113

   114

You may charge a fee for the physical act of transferring a copy, and

   115

you may at your option offer warranty protection in exchange for a fee.

   116

   117

  2. You may modify your copy or copies of the Program or any portion

   118

of it, thus forming a work based on the Program, and copy and

   119

distribute such modifications or work under the terms of Section 1

   120

above, provided that you also meet all of these conditions:

   121

   122

    a) You must cause the modified files to carry prominent notices

   123

    stating that you changed the files and the date of any change.

   124

   125

    b) You must cause any work that you distribute or publish, that in

   126

    whole or in part contains or is derived from the Program or any

   127

    part thereof, to be licensed as a whole at no charge to all third

   128

    parties under the terms of this License.

   129

   130

    c) If the modified program normally reads commands interactively

   131

    when run, you must cause it, when started running for such

   132

    interactive use in the most ordinary way, to print or display an

   133

    announcement including an appropriate copyright notice and a

   134

    notice that there is no warranty (or else, saying that you provide

   135

    a warranty) and that users may redistribute the program under

   136

    these conditions, and telling the user how to view a copy of this

   137

    License.  (Exception: if the Program itself is interactive but

   138

    does not normally print such an announcement, your work based on

   139

    the Program is not required to print an announcement.)

   140

   141

These requirements apply to the modified work as a whole.  If

   142

identifiable sections of that work are not derived from the Program,

   143

and can be reasonably considered independent and separate works in

   144

themselves, then this License, and its terms, do not apply to those

   145

sections when you distribute them as separate works.  But when you

   146

distribute the same sections as part of a whole which is a work based

   147

on the Program, the distribution of the whole must be on the terms of

   148

this License, whose permissions for other licensees extend to the

   149

entire whole, and thus to each and every part regardless of who wrote it.

   150

   151

Thus, it is not the intent of this section to claim rights or contest

   152

your rights to work written entirely by you; rather, the intent is to

   153

exercise the right to control the distribution of derivative or

   154

collective works based on the Program.

   155

   156

In addition, mere aggregation of another work not based on the Program

   157

with the Program (or with a work based on the Program) on a volume of

   158

a storage or distribution medium does not bring the other work under

   159

the scope of this License.

   160

   161

  3. You may copy and distribute the Program (or a work based on it,

   162

under Section 2) in object code or executable form under the terms of

   163

Sections 1 and 2 above provided that you also do one of the following:

   164

   165

    a) Accompany it with the complete corresponding machine-readable

   166

    source code, which must be distributed under the terms of Sections

   167

    1 and 2 above on a medium customarily used for software interchange; or,

   168

   169

    b) Accompany it with a written offer, valid for at least three

   170

    years, to give any third party, for a charge no more than your

   171

    cost of physically performing source distribution, a complete

   172

    machine-readable copy of the corresponding source code, to be

   173

    distributed under the terms of Sections 1 and 2 above on a medium

   174

    customarily used for software interchange; or,

   175

   176

    c) Accompany it with the information you received as to the offer

   177

    to distribute corresponding source code.  (This alternative is

   178

    allowed only for noncommercial distribution and only if you

   179

    received the program in object code or executable form with such

   180

    an offer, in accord with Subsection b above.)

   181

   182

The source code for a work means the preferred form of the work for

   183

making modifications to it.  For an executable work, complete source

   184

code means all the source code for all modules it contains, plus any

   185

associated interface definition files, plus the scripts used to

   186

control compilation and installation of the executable.  However, as a

   187

special exception, the source code distributed need not include

   188

anything that is normally distributed (in either source or binary

   189

form) with the major components (compiler, kernel, and so on) of the

   190

operating system on which the executable runs, unless that component

   191

itself accompanies the executable.

   192

   193

If distribution of executable or object code is made by offering

   194

access to copy from a designated place, then offering equivalent

   195

access to copy the source code from the same place counts as

   196

distribution of the source code, even though third parties are not

   197

compelled to copy the source along with the object code.

   198

   199

  4. You may not copy, modify, sublicense, or distribute the Program

   200

except as expressly provided under this License.  Any attempt

   201

otherwise to copy, modify, sublicense or distribute the Program is

   202

void, and will automatically terminate your rights under this License.

   203

However, parties who have received copies, or rights, from you under

   204

this License will not have their licenses terminated so long as such

   205

parties remain in full compliance.

   206

   207

  5. You are not required to accept this License, since you have not

   208

signed it.  However, nothing else grants you permission to modify or

   209

distribute the Program or its derivative works.  These actions are

   210

prohibited by law if you do not accept this License.  Therefore, by

   211

modifying or distributing the Program (or any work based on the

   212

Program), you indicate your acceptance of this License to do so, and

   213

all its terms and conditions for copying, distributing or modifying

   214

the Program or works based on it.

   215

   216

  6. Each time you redistribute the Program (or any work based on the

   217

Program), the recipient automatically receives a license from the

   218

original licensor to copy, distribute or modify the Program subject to

   219

these terms and conditions.  You may not impose any further

   220

restrictions on the recipients' exercise of the rights granted herein.

   221

You are not responsible for enforcing compliance by third parties to

   222

this License.

   223

   224

  7. If, as a consequence of a court judgment or allegation of patent

   225

infringement or for any other reason (not limited to patent issues),

   226

conditions are imposed on you (whether by court order, agreement or

   227

otherwise) that contradict the conditions of this License, they do not

   228

excuse you from the conditions of this License.  If you cannot

   229

distribute so as to satisfy simultaneously your obligations under this

   230

License and any other pertinent obligations, then as a consequence you

   231

may not distribute the Program at all.  For example, if a patent

   232

license would not permit royalty-free redistribution of the Program by

   233

all those who receive copies directly or indirectly through you, then

   234

the only way you could satisfy both it and this License would be to

   235

refrain entirely from distribution of the Program.

   236

   237

If any portion of this section is held invalid or unenforceable under

   238

any particular circumstance, the balance of the section is intended to

   239

apply and the section as a whole is intended to apply in other

   240

circumstances.

   241

   242

It is not the purpose of this section to induce you to infringe any

   243

patents or other property right claims or to contest validity of any

   244

such claims; this section has the sole purpose of protecting the

   245

integrity of the free software distribution system, which is

   246

implemented by public license practices.  Many people have made

   247

generous contributions to the wide range of software distributed

   248

through that system in reliance on consistent application of that

   249

system; it is up to the author/donor to decide if he or she is willing

   250

to distribute software through any other system and a licensee cannot

   251

impose that choice.

   252

   253

This section is intended to make thoroughly clear what is believed to

   254

be a consequence of the rest of this License.

   255

   256

  8. If the distribution and/or use of the Program is restricted in

   257

certain countries either by patents or by copyrighted interfaces, the

   258

original copyright holder who places the Program under this License

   259

may add an explicit geographical distribution limitation excluding

   260

those countries, so that distribution is permitted only in or among

   261

countries not thus excluded.  In such case, this License incorporates

   262

the limitation as if written in the body of this License.

   263

   264

  9. The Free Software Foundation may publish revised and/or new versions

   265

of the General Public License from time to time.  Such new versions will

   266

be similar in spirit to the present version, but may differ in detail to

   267

address new problems or concerns.

   268

   269

Each version is given a distinguishing version number.  If the Program

   270

specifies a version number of this License which applies to it and "any

   271

later version", you have the option of following the terms and conditions

   272

either of that version or of any later version published by the Free

   273

Software Foundation.  If the Program does not specify a version number of

   274

this License, you may choose any version ever published by the Free Software

   275

Foundation.

   276

   277

  10. If you wish to incorporate parts of the Program into other free

   278

programs whose distribution conditions are different, write to the author

   279

to ask for permission.  For software which is copyrighted by the Free

   280

Software Foundation, write to the Free Software Foundation; we sometimes

   281

make exceptions for this.  Our decision will be guided by the two goals

   282

of preserving the free status of all derivatives of our free software and

   283

of promoting the sharing and reuse of software generally.

   284

   285

			    NO WARRANTY

   286

   287

  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

   288

FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN

   289

OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

   290

PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

   291

OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

   292

MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS

   293

TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

   294

PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

   295

REPAIR OR CORRECTION.

   296

   297

  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

   298

WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

   299

REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

   300

INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

   301

OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

   302

TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

   303

YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

   304

PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

   305

POSSIBILITY OF SUCH DAMAGES.

   306

   307

		     END OF TERMS AND CONDITIONS
