rust: remove `atty` dependency
It is fully replaced with the now stable `std::io::IsTerminal` trait.
This was the last dependency flagged as a warning by `cargo audit`,
aside from `cpython` which we know about all too well: the plan is to
transition to PyO3 soon-ish.

9 Preamble |
394 | 10 |
11 The licenses for most software are designed to take away your | |
12 freedom to share and change it. By contrast, the GNU General Public | |
13 License is intended to guarantee your freedom to share and change free | |
14 software--to make sure the software is free for all its users. This | |
15 General Public License applies to most of the Free Software | |
16 Foundation's software and to any other program whose authors commit to | |
17 using it. (Some other Free Software Foundation software is covered by | |

18 the GNU Lesser General Public License instead.) You can apply it to |
394 | 19 your programs, too. |
20 | |
21 When we speak of free software, we are referring to freedom, not | |
22 price. Our General Public Licenses are designed to make sure that you | |
23 have the freedom to distribute copies of free software (and charge for | |
24 this service if you wish), that you receive source code or can get it | |
25 if you want it, that you can change the software or use pieces of it | |
26 in new free programs; and that you know you can do these things. | |
27 | |
28 To protect your rights, we need to make restrictions that forbid | |
29 anyone to deny you these rights or to ask you to surrender the rights. | |
30 These restrictions translate to certain responsibilities for you if you | |
31 distribute copies of the software, or if you modify it. | |
32 | |
33 For example, if you distribute copies of such a program, whether | |
34 gratis or for a fee, you must give the recipients all the rights that | |
35 you have. You must make sure that they, too, receive or can get the | |
36 source code. And you must show them these terms so they know their | |
37 rights. | |
38 | |
39 We protect your rights with two steps: (1) copyright the software, and | |
40 (2) offer you this license which gives you legal permission to copy, | |
41 distribute and/or modify the software. | |
42 | |
43 Also, for each author's protection and ours, we want to make certain | |
44 that everyone understands that there is no warranty for this free | |
45 software. If the software is modified by someone else and passed on, we | |
46 want its recipients to know that what they have is not the original, so | |
47 that any problems introduced by others will not reflect on the original | |
48 authors' reputations. | |
49 | |
50 Finally, any free program is threatened constantly by software | |
51 patents. We wish to avoid the danger that redistributors of a free | |
52 program will individually obtain patent licenses, in effect making the | |
53 program proprietary. To prevent this, we have made it clear that any | |
54 patent must be licensed for everyone's free use or not licensed at all. | |
55 | |
56 The precise terms and conditions for copying, distribution and | |
57 modification follow. | |

59 GNU GENERAL PUBLIC LICENSE |
394 | 60 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
61 | |
62 0. This License applies to any program or other work which contains | |
63 a notice placed by the copyright holder saying it may be distributed | |
64 under the terms of this General Public License. The "Program", below, | |
65 refers to any such program or work, and a "work based on the Program" | |
66 means either the Program or any derivative work under copyright law: | |
67 that is to say, a work containing the Program or a portion of it, | |
68 either verbatim or with modifications and/or translated into another | |
69 language. (Hereinafter, translation is included without limitation in | |
70 the term "modification".) Each licensee is addressed as "you". | |
71 | |
72 Activities other than copying, distribution and modification are not | |
73 covered by this License; they are outside its scope. The act of | |
74 running the Program is not restricted, and the output from the Program | |
75 is covered only if its contents constitute a work based on the | |
76 Program (independent of having been made by running the Program). | |
77 Whether that is true depends on what the Program does. | |
78 | |
79 1. You may copy and distribute verbatim copies of the Program's | |
80 source code as you receive it, in any medium, provided that you | |
81 conspicuously and appropriately publish on each copy an appropriate | |
82 copyright notice and disclaimer of warranty; keep intact all the | |
83 notices that refer to this License and to the absence of any warranty; | |
84 and give any other recipients of the Program a copy of this License | |
85 along with the Program. | |
86 | |
87 You may charge a fee for the physical act of transferring a copy, and | |
88 you may at your option offer warranty protection in exchange for a fee. | |
89 | |
90 2. You may modify your copy or copies of the Program or any portion | |
91 of it, thus forming a work based on the Program, and copy and | |
92 distribute such modifications or work under the terms of Section 1 | |
93 above, provided that you also meet all of these conditions: | |
94 | |
95 a) You must cause the modified files to carry prominent notices | |
96 stating that you changed the files and the date of any change. | |
97 | |
98 b) You must cause any work that you distribute or publish, that in | |
99 whole or in part contains or is derived from the Program or any | |
100 part thereof, to be licensed as a whole at no charge to all third | |
101 parties under the terms of this License. | |
102 | |
103 c) If the modified program normally reads commands interactively | |
104 when run, you must cause it, when started running for such | |
105 interactive use in the most ordinary way, to print or display an | |
106 announcement including an appropriate copyright notice and a | |
107 notice that there is no warranty (or else, saying that you provide | |
108 a warranty) and that users may redistribute the program under | |
109 these conditions, and telling the user how to view a copy of this | |
110 License. (Exception: if the Program itself is interactive but | |
111 does not normally print such an announcement, your work based on | |
112 the Program is not required to print an announcement.) | |

|
113 |
394 | 114 These requirements apply to the modified work as a whole. If |
115 identifiable sections of that work are not derived from the Program, | |
116 and can be reasonably considered independent and separate works in | |
117 themselves, then this License, and its terms, do not apply to those | |
118 sections when you distribute them as separate works. But when you | |
119 distribute the same sections as part of a whole which is a work based | |
120 on the Program, the distribution of the whole must be on the terms of | |
121 this License, whose permissions for other licensees extend to the | |
122 entire whole, and thus to each and every part regardless of who wrote it. | |
123 | |
124 Thus, it is not the intent of this section to claim rights or contest | |
125 your rights to work written entirely by you; rather, the intent is to | |
126 exercise the right to control the distribution of derivative or | |
127 collective works based on the Program. | |
128 | |
129 In addition, mere aggregation of another work not based on the Program | |
130 with the Program (or with a work based on the Program) on a volume of | |
131 a storage or distribution medium does not bring the other work under | |
132 the scope of this License. | |
133 | |
134 3. You may copy and distribute the Program (or a work based on it, | |
135 under Section 2) in object code or executable form under the terms of | |
136 Sections 1 and 2 above provided that you also do one of the following: | |
137 | |
138 a) Accompany it with the complete corresponding machine-readable | |
139 source code, which must be distributed under the terms of Sections | |
140 1 and 2 above on a medium customarily used for software interchange; or, | |
141 | |
142 b) Accompany it with a written offer, valid for at least three | |
143 years, to give any third party, for a charge no more than your | |
144 cost of physically performing source distribution, a complete | |
145 machine-readable copy of the corresponding source code, to be | |
146 distributed under the terms of Sections 1 and 2 above on a medium | |
147 customarily used for software interchange; or, | |
148 | |
149 c) Accompany it with the information you received as to the offer | |
150 to distribute corresponding source code. (This alternative is | |
151 allowed only for noncommercial distribution and only if you | |
152 received the program in object code or executable form with such | |
153 an offer, in accord with Subsection b above.) | |
154 | |
155 The source code for a work means the preferred form of the work for | |
156 making modifications to it. For an executable work, complete source | |
157 code means all the source code for all modules it contains, plus any | |
158 associated interface definition files, plus the scripts used to | |
159 control compilation and installation of the executable. However, as a | |
160 special exception, the source code distributed need not include | |
161 anything that is normally distributed (in either source or binary | |
162 form) with the major components (compiler, kernel, and so on) of the | |
163 operating system on which the executable runs, unless that component | |
164 itself accompanies the executable. | |
165 | |
166 If distribution of executable or object code is made by offering | |
167 access to copy from a designated place, then offering equivalent | |
168 access to copy the source code from the same place counts as | |
169 distribution of the source code, even though third parties are not | |
170 compelled to copy the source along with the object code. | |

171 |
394 | 172 4. You may not copy, modify, sublicense, or distribute the Program |
173 except as expressly provided under this License. Any attempt | |
174 otherwise to copy, modify, sublicense or distribute the Program is | |
175 void, and will automatically terminate your rights under this License. | |
176 However, parties who have received copies, or rights, from you under | |
177 this License will not have their licenses terminated so long as such | |
178 parties remain in full compliance. | |
179 | |
180 5. You are not required to accept this License, since you have not | |
181 signed it. However, nothing else grants you permission to modify or | |
182 distribute the Program or its derivative works. These actions are | |
183 prohibited by law if you do not accept this License. Therefore, by | |
184 modifying or distributing the Program (or any work based on the | |
185 Program), you indicate your acceptance of this License to do so, and | |
186 all its terms and conditions for copying, distributing or modifying | |
187 the Program or works based on it. | |
188 | |
189 6. Each time you redistribute the Program (or any work based on the | |
190 Program), the recipient automatically receives a license from the | |
191 original licensor to copy, distribute or modify the Program subject to | |
192 these terms and conditions. You may not impose any further | |
193 restrictions on the recipients' exercise of the rights granted herein. | |
194 You are not responsible for enforcing compliance by third parties to | |
195 this License. | |
196 | |
197 7. If, as a consequence of a court judgment or allegation of patent | |
198 infringement or for any other reason (not limited to patent issues), | |
199 conditions are imposed on you (whether by court order, agreement or | |
200 otherwise) that contradict the conditions of this License, they do not | |
201 excuse you from the conditions of this License. If you cannot | |
202 distribute so as to satisfy simultaneously your obligations under this | |
203 License and any other pertinent obligations, then as a consequence you | |
204 may not distribute the Program at all. For example, if a patent | |
205 license would not permit royalty-free redistribution of the Program by | |
206 all those who receive copies directly or indirectly through you, then | |
207 the only way you could satisfy both it and this License would be to | |
208 refrain entirely from distribution of the Program. | |
209 | |
210 If any portion of this section is held invalid or unenforceable under | |
211 any particular circumstance, the balance of the section is intended to | |
212 apply and the section as a whole is intended to apply in other | |
213 circumstances. | |
214 | |
215 It is not the purpose of this section to induce you to infringe any | |
216 patents or other property right claims or to contest validity of any | |
217 such claims; this section has the sole purpose of protecting the | |
218 integrity of the free software distribution system, which is | |
219 implemented by public license practices. Many people have made | |
220 generous contributions to the wide range of software distributed | |
221 through that system in reliance on consistent application of that | |
222 system; it is up to the author/donor to decide if he or she is willing | |
223 to distribute software through any other system and a licensee cannot | |
224 impose that choice. | |
225 | |
226 This section is intended to make thoroughly clear what is believed to | |
227 be a consequence of the rest of this License. | |

228 |
394 | 229 8. If the distribution and/or use of the Program is restricted in |
230 certain countries either by patents or by copyrighted interfaces, the | |
231 original copyright holder who places the Program under this License | |
232 may add an explicit geographical distribution limitation excluding | |
233 those countries, so that distribution is permitted only in or among | |
234 countries not thus excluded. In such case, this License incorporates | |
235 the limitation as if written in the body of this License. | |
236 | |
237 9. The Free Software Foundation may publish revised and/or new versions | |
238 of the General Public License from time to time. Such new versions will | |
239 be similar in spirit to the present version, but may differ in detail to | |
240 address new problems or concerns. | |
241 | |
242 Each version is given a distinguishing version number. If the Program | |
243 specifies a version number of this License which applies to it and "any | |
244 later version", you have the option of following the terms and conditions | |
245 either of that version or of any later version published by the Free | |
246 Software Foundation. If the Program does not specify a version number of | |
247 this License, you may choose any version ever published by the Free Software | |
248 Foundation. | |
249 | |
250 10. If you wish to incorporate parts of the Program into other free | |
251 programs whose distribution conditions are different, write to the author | |
252 to ask for permission. For software which is copyrighted by the Free | |
253 Software Foundation, write to the Free Software Foundation; we sometimes | |
254 make exceptions for this. Our decision will be guided by the two goals | |
255 of preserving the free status of all derivatives of our free software and | |
256 of promoting the sharing and reuse of software generally. | |

258 NO WARRANTY |
394 | 259 |
260 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY | |
261 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN | |
262 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES | |
263 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED | |
264 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF | |
265 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS | |
266 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE | |
267 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, | |
268 REPAIR OR CORRECTION. | |
269 | |
270 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
271 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR | |
272 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
273 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING | |
274 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED | |
275 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY | |
276 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER | |
277 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE | |
278 POSSIBILITY OF SUCH DAMAGES. | |

282 How to Apply These Terms to Your New Programs |
394 | 283 |
284 If you develop a new program, and you want it to be of the greatest | |
285 possible use to the public, the best way to achieve this is to make it | |
286 free software which everyone can redistribute and change under these terms. | |
287 | |
288 To do so, attach the following notices to the program. It is safest | |
289 to attach them to the start of each source file to most effectively | |
290 convey the exclusion of warranty; and each file should have at least | |
291 the "copyright" line and a pointer to where the full notice is found. | |
292 | |
293 <one line to give the program's name and a brief idea of what it does.> | |
294 Copyright (C) <year> <name of author> | |
295 | |
296 This program is free software; you can redistribute it and/or modify | |
297 it under the terms of the GNU General Public License as published by | |
298 the Free Software Foundation; either version 2 of the License, or | |
299 (at your option) any later version. | |
300 | |
301 This program is distributed in the hope that it will be useful, | |
302 but WITHOUT ANY WARRANTY; without even the implied warranty of | |
303 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
304 GNU General Public License for more details. | |

315 Gnomovision version 69, Copyright (C) year name of author |
394 | 316 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
317 This is free software, and you are welcome to redistribute it | |
318 under certain conditions; type `show c' for details. | |
319 | |
320 The hypothetical commands `show w' and `show c' should show the appropriate | |
321 parts of the General Public License. Of course, the commands you use may | |
322 be called something other than `show w' and `show c'; they could even be | |
323 mouse-clicks or menu items--whatever suits your program. | |
324 | |
325 You should also get your employer (if you work as a programmer) or your | |
326 school, if any, to sign a "copyright disclaimer" for the program, if | |
327 necessary. Here is a sample; alter the names: | |
328 | |
329 Yoyodyne, Inc., hereby disclaims all copyright interest in the program | |
330 `Gnomovision' (which makes passes at compilers) written by James Hacker. | |
331 | |
332 <signature of Ty Coon>, 1 April 1989 | |
333 Ty Coon, President of Vice | |
334 | |
335 This General Public License does not permit incorporating your program into | |
336 proprietary programs. If your program is a subroutine library, you may | |
337 consider it more useful to permit linking proprietary applications with the | |
