7 1 Qwt License
10 2 Version 1.0, January 1, 2003
11 3
12 4 The Qwt library and included programs are provided under the terms
13 5 of the GNU LESSER GENERAL PUBLIC LICENSE (LGPL) with the following
14 6 exceptions:
15 7
16 8 1. Widgets that are subclassed from Qwt widgets do not
17 9 constitute a derivative work.
18 10
19 11 2. Static linking of applications and widgets to the
20 12 Qwt library does not constitute a derivative work
21 13 and does not require the author to provide source
22 14 code for the application or widget, use the shared
23 15 Qwt libraries, or link their applications or
24 16 widgets against a user-supplied version of Qwt.
25 17
26 18 If you link the application or widget to a modified
27 19 version of Qwt, then the changes to Qwt must be
28 20 provided under the terms of the LGPL in sections
29 21 1, 2, and 4.
30 22
31 23 3. You do not have to provide a copy of the Qwt license
32 24 with programs that are linked to the Qwt library, nor
33 25 do you have to identify the Qwt license in your
34 26 program or documentation as required by section 6
35 27 of the LGPL.
36 28
37 29
38 30 However, programs must still identify their use of Qwt.
39 31 The following example statement can be included in user
40 32 documentation to satisfy this requirement:
41 33
42 34 [program/widget] is based in part on the work of
43 35 the Qwt project (http://qwt.sf.net).

52 44 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
53 45 Everyone is permitted to copy and distribute verbatim copies
54 46 of this license document, but changing it is not allowed.

56 48 [This is the first released version of the Lesser GPL. It also counts
57 49 as the successor of the GNU Library Public License, version 2, hence
58 50 the version number 2.1.]
59 51
60 52 Preamble
61 53
62 54 The licenses for most software are designed to take away your
63 55 freedom to share and change it. By contrast, the GNU General Public
64 56 Licenses are intended to guarantee your freedom to share and change
65 57 free software--to make sure the software is free for all its users.
66 58
67 59 This license, the Lesser General Public License, applies to some
68 60 specially designated software packages--typically libraries--of the
69 61 Free Software Foundation and other authors who decide to use it. You
70 62 can use it too, but we suggest you first think carefully about whether
71 63 this license or the ordinary General Public License is the better
72 64 strategy to use in any particular case, based on the explanations below.
73 65
74 66 When we speak of free software, we are referring to freedom of use,
75 67 not price. Our General Public Licenses are designed to make sure that
76 68 you have the freedom to distribute copies of free software (and charge
77 69 for this service if you wish); that you receive source code or can get
78 70 it if you want it; that you can change the software and use pieces of
79 71 it in new free programs; and that you are informed that you can do
80 72 these things.
81 73
82 74 To protect your rights, we need to make restrictions that forbid
83 75 distributors to deny you these rights or to ask you to surrender these
84 76 rights. These restrictions translate to certain responsibilities for
85 77 you if you distribute copies of the library or if you modify it.
86 78
87 79 For example, if you distribute copies of the library, whether gratis
88 80 or for a fee, you must give the recipients all the rights that we gave
89 81 you. You must make sure that they, too, receive or can get the source
90 82 code. If you link other code with the library, you must provide
91 83 complete object files to the recipients, so that they can relink them
92 84 with the library after making changes to the library and recompiling
93 85 it. And you must show them these terms so they know their rights.
94 86
95 87 We protect your rights with a two-step method: (1) we copyright the
96 88 library, and (2) we offer you this license, which gives you legal
97 89 permission to copy, distribute and/or modify the library.
98 90
99 91 To protect each distributor, we want to make it very clear that
100 92 there is no warranty for the free library. Also, if the library is
101 93 modified by someone else and passed on, the recipients should know
102 94 that what they have is not the original version, so that the original
103 95 author's reputation will not be affected by problems that might be
104 96 introduced by others.
105 97
106 98 Finally, software patents pose a constant threat to the existence of
107 99 any free program. We wish to make sure that a company cannot
108 100 effectively restrict the users of a free program by obtaining a
109 101 restrictive license from a patent holder. Therefore, we insist that
110 102 any patent license obtained for a version of the library must be
111 103 consistent with the full freedom of use specified in this license.
112 104
113 105 Most GNU software, including some libraries, is covered by the
114 106 ordinary GNU General Public License. This license, the GNU Lesser
115 107 General Public License, applies to certain designated libraries, and
116 108 is quite different from the ordinary General Public License. We use
117 109 this license for certain libraries in order to permit linking those
118 110 libraries into non-free programs.
119 111
120 112 When a program is linked with a library, whether statically or using
121 113 a shared library, the combination of the two is legally speaking a
122 114 combined work, a derivative of the original library. The ordinary
123 115 General Public License therefore permits such linking only if the
124 116 entire combination fits its criteria of freedom. The Lesser General
125 117 Public License permits more lax criteria for linking other code with
126 118 the library.
127 119
128 120 We call this license the "Lesser" General Public License because it
129 121 does Less to protect the user's freedom than the ordinary General
130 122 Public License. It also provides other free software developers Less
131 123 of an advantage over competing non-free programs. These disadvantages
132 124 are the reason we use the ordinary General Public License for many
133 125 libraries. However, the Lesser license provides advantages in certain
134 126 special circumstances.
135 127
136 128 For example, on rare occasions, there may be a special need to
137 129 encourage the widest possible use of a certain library, so that it becomes
138 130 a de-facto standard. To achieve this, non-free programs must be
139 131 allowed to use the library. A more frequent case is that a free
140 132 library does the same job as widely used non-free libraries. In this
141 133 case, there is little to gain by limiting the free library to free
142 134 software only, so we use the Lesser General Public License.
143 135
144 136 In other cases, permission to use a particular library in non-free
145 137 programs enables a greater number of people to use a large body of
146 138 free software. For example, permission to use the GNU C Library in
147 139 non-free programs enables many more people to use the whole GNU
148 140 operating system, as well as its variant, the GNU/Linux operating
149 141 system.
150 142
151 143 Although the Lesser General Public License is Less protective of the
152 144 users' freedom, it does ensure that the user of a program that is
153 145 linked with the Library has the freedom and the wherewithal to run
154 146 that program using a modified version of the Library.
155 147
156 148 The precise terms and conditions for copying, distribution and
157 149 modification follow. Pay close attention to the difference between a
158 150 "work based on the library" and a "work that uses the library". The
159 151 former contains code derived from the library, whereas the latter must
160 152 be combined with the library in order to run.
161 153
162 154 GNU LESSER GENERAL PUBLIC LICENSE
163 155 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
164 156
165 157 0. This License Agreement applies to any software library or other
166 158 program which contains a notice placed by the copyright holder or
167 159 other authorized party saying it may be distributed under the terms of
168 160 this Lesser General Public License (also called "this License").
169 161 Each licensee is addressed as "you".
170 162
171 163 A "library" means a collection of software functions and/or data
172 164 prepared so as to be conveniently linked with application programs
173 165 (which use some of those functions and data) to form executables.
174 166
175 167 The "Library", below, refers to any such software library or work
176 168 which has been distributed under these terms. A "work based on the
177 169 Library" means either the Library or any derivative work under
178 170 copyright law: that is to say, a work containing the Library or a
179 171 portion of it, either verbatim or with modifications and/or translated
180 172 straightforwardly into another language. (Hereinafter, translation is
181 173 included without limitation in the term "modification".)
182 174
183 175 "Source code" for a work means the preferred form of the work for
184 176 making modifications to it. For a library, complete source code means
185 177 all the source code for all modules it contains, plus any associated
186 178 interface definition files, plus the scripts used to control compilation
187 179 and installation of the library.
188 180
189 181 Activities other than copying, distribution and modification are not
190 182 covered by this License; they are outside its scope. The act of
191 183 running a program using the Library is not restricted, and output from
192 184 such a program is covered only if its contents constitute a work based
193 185 on the Library (independent of the use of the Library in a tool for
194 186 writing it). Whether that is true depends on what the Library does
195 187 and what the program that uses the Library does.
196 188
197 189 1. You may copy and distribute verbatim copies of the Library's
198 190 complete source code as you receive it, in any medium, provided that
199 191 you conspicuously and appropriately publish on each copy an
200 192 appropriate copyright notice and disclaimer of warranty; keep intact
201 193 all the notices that refer to this License and to the absence of any
202 194 warranty; and distribute a copy of this License along with the
203 195 Library.
204 196
205 197 You may charge a fee for the physical act of transferring a copy,
206 198 and you may at your option offer warranty protection in exchange for a
207 199 fee.
208 200
209 201 2. You may modify your copy or copies of the Library or any portion
210 202 of it, thus forming a work based on the Library, and copy and
211 203 distribute such modifications or work under the terms of Section 1
212 204 above, provided that you also meet all of these conditions:
213 205
214 206 a) The modified work must itself be a software library.
215 207
216 208 b) You must cause the files modified to carry prominent notices
217 209 stating that you changed the files and the date of any change.
218 210
219 211 c) You must cause the whole of the work to be licensed at no
220 212 charge to all third parties under the terms of this License.
221 213
222 214 d) If a facility in the modified Library refers to a function or a
223 215 table of data to be supplied by an application program that uses
224 216 the facility, other than as an argument passed when the facility
225 217 is invoked, then you must make a good faith effort to ensure that,
226 218 in the event an application does not supply such function or
227 219 table, the facility still operates, and performs whatever part of
228 220 its purpose remains meaningful.
229 221
230 222 (For example, a function in a library to compute square roots has
231 223 a purpose that is entirely well-defined independent of the
232 224 application. Therefore, Subsection 2d requires that any
233 225 application-supplied function or table used by this function must
234 226 be optional: if the application does not supply it, the square
235 227 root function must still compute square roots.)
236 228
237 229 These requirements apply to the modified work as a whole. If
238 230 identifiable sections of that work are not derived from the Library,
239 231 and can be reasonably considered independent and separate works in
240 232 themselves, then this License, and its terms, do not apply to those
241 233 sections when you distribute them as separate works. But when you
242 234 distribute the same sections as part of a whole which is a work based
243 235 on the Library, the distribution of the whole must be on the terms of
244 236 this License, whose permissions for other licensees extend to the
245 237 entire whole, and thus to each and every part regardless of who wrote
246 238 it.
247 239
248 240 Thus, it is not the intent of this section to claim rights or contest
249 241 your rights to work written entirely by you; rather, the intent is to
250 242 exercise the right to control the distribution of derivative or
251 243 collective works based on the Library.
252 244
253 245 In addition, mere aggregation of another work not based on the Library
254 246 with the Library (or with a work based on the Library) on a volume of
255 247 a storage or distribution medium does not bring the other work under
256 248 the scope of this License.
257 249
258 250 3. You may opt to apply the terms of the ordinary GNU General Public
259 251 License instead of this License to a given copy of the Library. To do
260 252 this, you must alter all the notices that refer to this License, so
261 253 that they refer to the ordinary GNU General Public License, version 2,
262 254 instead of to this License. (If a newer version than version 2 of the
263 255 ordinary GNU General Public License has appeared, then you can specify
264 256 that version instead if you wish.) Do not make any other change in
265 257 these notices.
266 258
267 259 Once this change is made in a given copy, it is irreversible for
268 260 that copy, so the ordinary GNU General Public License applies to all
269 261 subsequent copies and derivative works made from that copy.
270 262
271 263 This option is useful when you wish to copy part of the code of
272 264 the Library into a program that is not a library.
273 265
274 266 4. You may copy and distribute the Library (or a portion or
275 267 derivative of it, under Section 2) in object code or executable form
276 268 under the terms of Sections 1 and 2 above provided that you accompany
277 269 it with the complete corresponding machine-readable source code, which
278 270 must be distributed under the terms of Sections 1 and 2 above on a
279 271 medium customarily used for software interchange.
280 272
281 273 If distribution of object code is made by offering access to copy
282 274 from a designated place, then offering equivalent access to copy the
283 275 source code from the same place satisfies the requirement to
284 276 distribute the source code, even though third parties are not
285 277 compelled to copy the source along with the object code.
286 278
287 279 5. A program that contains no derivative of any portion of the
288 280 Library, but is designed to work with the Library by being compiled or
289 281 linked with it, is called a "work that uses the Library". Such a
290 282 work, in isolation, is not a derivative work of the Library, and
291 283 therefore falls outside the scope of this License.
292 284
293 285 However, linking a "work that uses the Library" with the Library
294 286 creates an executable that is a derivative of the Library (because it
295 287 contains portions of the Library), rather than a "work that uses the
296 288 library". The executable is therefore covered by this License.
297 289 Section 6 states terms for distribution of such executables.
298 290
299 291 When a "work that uses the Library" uses material from a header file
300 292 that is part of the Library, the object code for the work may be a
301 293 derivative work of the Library even though the source code is not.
302 294 Whether this is true is especially significant if the work can be
303 295 linked without the Library, or if the work is itself a library. The
304 296 threshold for this to be true is not precisely defined by law.
305 297
306 298 If such an object file uses only numerical parameters, data
307 299 structure layouts and accessors, and small macros and small inline
308 300 functions (ten lines or less in length), then the use of the object
309 301 file is unrestricted, regardless of whether it is legally a derivative
310 302 work. (Executables containing this object code plus portions of the
311 303 Library will still fall under Section 6.)
312 304
313 305 Otherwise, if the work is a derivative of the Library, you may
314 306 distribute the object code for the work under the terms of Section 6.
315 307 Any executables containing that work also fall under Section 6,
316 308 whether or not they are linked directly with the Library itself.
317 309
318 310 6. As an exception to the Sections above, you may also combine or
319 311 link a "work that uses the Library" with the Library to produce a
320 312 work containing portions of the Library, and distribute that work
321 313 under terms of your choice, provided that the terms permit
322 314 modification of the work for the customer's own use and reverse
323 315 engineering for debugging such modifications.
324 316
325 317 You must give prominent notice with each copy of the work that the
326 318 Library is used in it and that the Library and its use are covered by
327 319 this License. You must supply a copy of this License. If the work
328 320 during execution displays copyright notices, you must include the
329 321 copyright notice for the Library among them, as well as a reference
330 322 directing the user to the copy of this License. Also, you must do one
331 323 of these things:
332 324
333 325 a) Accompany the work with the complete corresponding
334 326 machine-readable source code for the Library including whatever
335 327 changes were used in the work (which must be distributed under
336 328 Sections 1 and 2 above); and, if the work is an executable linked
337 329 with the Library, with the complete machine-readable "work that
338 330 uses the Library", as object code and/or source code, so that the
339 331 user can modify the Library and then relink to produce a modified
340 332 executable containing the modified Library. (It is understood
341 333 that the user who changes the contents of definitions files in the
342 334 Library will not necessarily be able to recompile the application
343 335 to use the modified definitions.)
344 336
345 337 b) Use a suitable shared library mechanism for linking with the
346 338 Library. A suitable mechanism is one that (1) uses at run time a
347 339 copy of the library already present on the user's computer system,
348 340 rather than copying library functions into the executable, and (2)
349 341 will operate properly with a modified version of the library, if
350 342 the user installs one, as long as the modified version is
351 343 interface-compatible with the version that the work was made with.
352 344
353 345 c) Accompany the work with a written offer, valid for at
354 346 least three years, to give the same user the materials
355 347 specified in Subsection 6a, above, for a charge no more
356 348 than the cost of performing this distribution.
357 349
358 350 d) If distribution of the work is made by offering access to copy
359 351 from a designated place, offer equivalent access to copy the above
360 352 specified materials from the same place.
361 353
362 354 e) Verify that the user has already received a copy of these
363 355 materials or that you have already sent this user a copy.
364 356
365 357 For an executable, the required form of the "work that uses the
366 358 Library" must include any data and utility programs needed for
367 359 reproducing the executable from it. However, as a special exception,
368 360 the materials to be distributed need not include anything that is
369 361 normally distributed (in either source or binary form) with the major
370 362 components (compiler, kernel, and so on) of the operating system on
371 363 which the executable runs, unless that component itself accompanies
372 364 the executable.
373 365
374 366 It may happen that this requirement contradicts the license
375 367 restrictions of other proprietary libraries that do not normally
376 368 accompany the operating system. Such a contradiction means you cannot
377 369 use both them and the Library together in an executable that you
378 370 distribute.
379 371
380 372 7. You may place library facilities that are a work based on the
381 373 Library side-by-side in a single library together with other library
382 374 facilities not covered by this License, and distribute such a combined
383 375 library, provided that the separate distribution of the work based on
384 376 the Library and of the other library facilities is otherwise
385 377 permitted, and provided that you do these two things:
386 378
387 379 a) Accompany the combined library with a copy of the same work
388 380 based on the Library, uncombined with any other library
389 381 facilities. This must be distributed under the terms of the
390 382 Sections above.
391 383
392 384 b) Give prominent notice with the combined library of the fact
393 385 that part of it is a work based on the Library, and explaining
394 386 where to find the accompanying uncombined form of the same work.
395 387
396 388 8. You may not copy, modify, sublicense, link with, or distribute
397 389 the Library except as expressly provided under this License. Any
398 390 attempt otherwise to copy, modify, sublicense, link with, or
399 391 distribute the Library is void, and will automatically terminate your
400 392 rights under this License. However, parties who have received copies,
401 393 or rights, from you under this License will not have their licenses
402 394 terminated so long as such parties remain in full compliance.
403 395
404 396 9. You are not required to accept this License, since you have not
405 397 signed it. However, nothing else grants you permission to modify or
406 398 distribute the Library or its derivative works. These actions are
407 399 prohibited by law if you do not accept this License. Therefore, by
408 400 modifying or distributing the Library (or any work based on the
409 401 Library), you indicate your acceptance of this License to do so, and
410 402 all its terms and conditions for copying, distributing or modifying
411 403 the Library or works based on it.
412 404
413 405 10. Each time you redistribute the Library (or any work based on the
414 406 Library), the recipient automatically receives a license from the
415 407 original licensor to copy, distribute, link with or modify the Library
416 408 subject to these terms and conditions. You may not impose any further
417 409 restrictions on the recipients' exercise of the rights granted herein.
418 410 You are not responsible for enforcing compliance by third parties with
419 411 this License.
420 412
421 413 11. If, as a consequence of a court judgment or allegation of patent
422 414 infringement or for any other reason (not limited to patent issues),
423 415 conditions are imposed on you (whether by court order, agreement or
424 416 otherwise) that contradict the conditions of this License, they do not
425 417 excuse you from the conditions of this License. If you cannot
426 418 distribute so as to satisfy simultaneously your obligations under this
427 419 License and any other pertinent obligations, then as a consequence you
428 420 may not distribute the Library at all. For example, if a patent
429 421 license would not permit royalty-free redistribution of the Library by
430 422 all those who receive copies directly or indirectly through you, then
431 423 the only way you could satisfy both it and this License would be to
432 424 refrain entirely from distribution of the Library.
433 425
434 426 If any portion of this section is held invalid or unenforceable under any
435 427 particular circumstance, the balance of the section is intended to apply,
436 428 and the section as a whole is intended to apply in other circumstances.
437 429
438 430 It is not the purpose of this section to induce you to infringe any
439 431 patents or other property right claims or to contest validity of any
440 432 such claims; this section has the sole purpose of protecting the
441 433 integrity of the free software distribution system which is
442 434 implemented by public license practices. Many people have made
443 435 generous contributions to the wide range of software distributed
444 436 through that system in reliance on consistent application of that
445 437 system; it is up to the author/donor to decide if he or she is willing
446 438 to distribute software through any other system and a licensee cannot
447 439 impose that choice.
448 440
449 441 This section is intended to make thoroughly clear what is believed to
450 442 be a consequence of the rest of this License.
451 443
452 444 12. If the distribution and/or use of the Library is restricted in
453 445 certain countries either by patents or by copyrighted interfaces, the
454 446 original copyright holder who places the Library under this License may add
455 447 an explicit geographical distribution limitation excluding those countries,
456 448 so that distribution is permitted only in or among countries not thus
457 449 excluded. In such case, this License incorporates the limitation as if
458 450 written in the body of this License.
459 451
460 452 13. The Free Software Foundation may publish revised and/or new
461 453 versions of the Lesser General Public License from time to time.
462 454 Such new versions will be similar in spirit to the present version,
463 455 but may differ in detail to address new problems or concerns.
464 456
465 457 Each version is given a distinguishing version number. If the Library
466 458 specifies a version number of this License which applies to it and
467 459 "any later version", you have the option of following the terms and
468 460 conditions either of that version or of any later version published by
469 461 the Free Software Foundation. If the Library does not specify a
470 462 license version number, you may choose any version ever published by
471 463 the Free Software Foundation.
472 464
473 465 14. If you wish to incorporate parts of the Library into other free
474 466 programs whose distribution conditions are incompatible with these,
475 467 write to the author to ask for permission. For software which is
476 468 copyrighted by the Free Software Foundation, write to the Free
477 469 Software Foundation; we sometimes make exceptions for this. Our
478 470 decision will be guided by the two goals of preserving the free status
479 471 of all derivatives of our free software and of promoting the sharing
480 472 and reuse of software generally.
481 473
482 474 NO WARRANTY
483 475
484 476 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
485 477 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
486 478 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
487 479 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
488 480 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
489 481 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
490 482 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
491 483 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
492 484 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
493 485
494 486 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
495 487 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
496 488 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
497 489 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
498 490 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
499 491 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
500 492 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
501 493 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
502 494 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
503 495 DAMAGES.
504 496
505 497 END OF TERMS AND CONDITIONS
506 498
507 499 How to Apply These Terms to Your New Libraries
508 500
509 501 If you develop a new library, and you want it to be of the greatest
510 502 possible use to the public, we recommend making it free software that
511 503 everyone can redistribute and change. You can do so by permitting
512 504 redistribution under these terms (or, alternatively, under the terms of the
513 505 ordinary General Public License).
514 506
515 507 To apply these terms, attach the following notices to the library. It is
516 508 safest to attach them to the start of each source file to most effectively
517 509 convey the exclusion of warranty; and each file should have at least the
518 510 "copyright" line and a pointer to where the full notice is found.
519 511
520 512 <one line to give the library's name and a brief idea of what it does.>
521 513 Copyright (C) <year> <name of author>
522 514
523 515 This library is free software; you can redistribute it and/or
524 516 modify it under the terms of the GNU Lesser General Public
525 517 License as published by the Free Software Foundation; either
526 518 version 2.1 of the License, or (at your option) any later version.
527 519
528 520 This library is distributed in the hope that it will be useful,
529 521 but WITHOUT ANY WARRANTY; without even the implied warranty of
530 522 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
531 523 Lesser General Public License for more details.
532 524
533 525 You should have received a copy of the GNU Lesser General Public
534 526 License along with this library; if not, write to the Free Software
535 527 Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
536 528
537 529 Also add information on how to contact you by electronic and paper mail.
538 530
539 531 You should also get your employer (if you work as a programmer) or your
540 532 school, if any, to sign a "copyright disclaimer" for the library, if
541 533 necessary. Here is a sample; alter the names:
542 534

544 536 library `Frob' (a library for tweaking knobs) written by James Random Hacker.
