8
+    Everyone is permitted to copy and distribute verbatim copies
9
+    of this license document, but changing it is not allowed.
10
+
11
+    [This is the first released version of the Lesser GPL.  It also counts
12
+     as the successor of the GNU Library Public License, version 2, hence
13
+     the version number 2.1.]

+
15
+### Preamble
16
+
17
+The licenses for most software are designed to take away your freedom
18
+to share and change it. By contrast, the GNU General Public Licenses
19
+are intended to guarantee your freedom to share and change free
20
+software--to make sure the software is free for all its users.
21
+
22
+This license, the Lesser General Public License, applies to some
23
+specially designated software packages--typically libraries--of the
24
+Free Software Foundation and other authors who decide to use it. You
25
+can use it too, but we suggest you first think carefully about whether
26
+this license or the ordinary General Public License is the better
27
+strategy to use in any particular case, based on the explanations
28
+below.
29
+
30
+When we speak of free software, we are referring to freedom of use,
31
+not price. Our General Public Licenses are designed to make sure that
32
+you have the freedom to distribute copies of free software (and charge
33
+for this service if you wish); that you receive source code or can get
34
+it if you want it; that you can change the software and use pieces of
35
+it in new free programs; and that you are informed that you can do
36
+these things.
37
+
38
+To protect your rights, we need to make restrictions that forbid
39
+distributors to deny you these rights or to ask you to surrender these
40
+rights. These restrictions translate to certain responsibilities for
41
+you if you distribute copies of the library or if you modify it.
42
+
43
+For example, if you distribute copies of the library, whether gratis
44
+or for a fee, you must give the recipients all the rights that we gave
45
+you. You must make sure that they, too, receive or can get the source
46
+code. If you link other code with the library, you must provide
47
+complete object files to the recipients, so that they can relink them
48
+with the library after making changes to the library and recompiling
49
+it. And you must show them these terms so they know their rights.
50
+
51
+We protect your rights with a two-step method: (1) we copyright the
52
+library, and (2) we offer you this license, which gives you legal
53
+permission to copy, distribute and/or modify the library.
54
+
55
+To protect each distributor, we want to make it very clear that there
56
+is no warranty for the free library. Also, if the library is modified
57
+by someone else and passed on, the recipients should know that what
58
+they have is not the original version, so that the original author's
59
+reputation will not be affected by problems that might be introduced
60
+by others.
61
+
62
+Finally, software patents pose a constant threat to the existence of
63
+any free program. We wish to make sure that a company cannot
64
+effectively restrict the users of a free program by obtaining a
65
+restrictive license from a patent holder. Therefore, we insist that
66
+any patent license obtained for a version of the library must be
67
+consistent with the full freedom of use specified in this license.
68
+
69
+Most GNU software, including some libraries, is covered by the
70
+ordinary GNU General Public License. This license, the GNU Lesser
71
+General Public License, applies to certain designated libraries, and
72
+is quite different from the ordinary General Public License. We use
73
+this license for certain libraries in order to permit linking those
74
+libraries into non-free programs.
75
+
76
+When a program is linked with a library, whether statically or using a
77
+shared library, the combination of the two is legally speaking a
78
+combined work, a derivative of the original library. The ordinary
79
+General Public License therefore permits such linking only if the
80
+entire combination fits its criteria of freedom. The Lesser General
81
+Public License permits more lax criteria for linking other code with
82
+the library.
83
+
84
+We call this license the "Lesser" General Public License because it
85
+does Less to protect the user's freedom than the ordinary General
86
+Public License. It also provides other free software developers Less
87
+of an advantage over competing non-free programs. These disadvantages
88
+are the reason we use the ordinary General Public License for many
89
+libraries. However, the Lesser license provides advantages in certain
90
+special circumstances.
91
+
92
+For example, on rare occasions, there may be a special need to
93
+encourage the widest possible use of a certain library, so that it
94
+becomes a de-facto standard. To achieve this, non-free programs must
95
+be allowed to use the library. A more frequent case is that a free
96
+library does the same job as widely used non-free libraries. In this
97
+case, there is little to gain by limiting the free library to free
98
+software only, so we use the Lesser General Public License.
99
+
100
+In other cases, permission to use a particular library in non-free
101
+programs enables a greater number of people to use a large body of
102
+free software. For example, permission to use the GNU C Library in
103
+non-free programs enables many more people to use the whole GNU
104
+operating system, as well as its variant, the GNU/Linux operating
105
+system.
106
+
107
+Although the Lesser General Public License is Less protective of the
108
+users' freedom, it does ensure that the user of a program that is
109
+linked with the Library has the freedom and the wherewithal to run
110
+that program using a modified version of the Library.
111
+
112
+The precise terms and conditions for copying, distribution and
113
+modification follow. Pay close attention to the difference between a
114
+"work based on the library" and a "work that uses the library". The
115
+former contains code derived from the library, whereas the latter must
116
+be combined with the library in order to run.
117
+
118
+### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
119
+
120
+**0.** This License Agreement applies to any software library or other
121
+program which contains a notice placed by the copyright holder or
122
+other authorized party saying it may be distributed under the terms of
123
+this Lesser General Public License (also called "this License"). Each
124
+licensee is addressed as "you".
125
+
126
+A "library" means a collection of software functions and/or data
127
+prepared so as to be conveniently linked with application programs
128
+(which use some of those functions and data) to form executables.
129
+
130
+The "Library", below, refers to any such software library or work
131
+which has been distributed under these terms. A "work based on the
132
+Library" means either the Library or any derivative work under
133
+copyright law: that is to say, a work containing the Library or a
134
+portion of it, either verbatim or with modifications and/or translated
135
+straightforwardly into another language. (Hereinafter, translation is
136
+included without limitation in the term "modification".)
137
+
138
+"Source code" for a work means the preferred form of the work for
139
+making modifications to it. For a library, complete source code means
140
+all the source code for all modules it contains, plus any associated
141
+interface definition files, plus the scripts used to control
142
+compilation and installation of the library.
143
+
144
+Activities other than copying, distribution and modification are not
145
+covered by this License; they are outside its scope. The act of
146
+running a program using the Library is not restricted, and output from
147
+such a program is covered only if its contents constitute a work based
148
+on the Library (independent of the use of the Library in a tool for
149
+writing it). Whether that is true depends on what the Library does and
150
+what the program that uses the Library does.
151
+
152
+**1.** You may copy and distribute verbatim copies of the Library's
153
+complete source code as you receive it, in any medium, provided that
154
+you conspicuously and appropriately publish on each copy an
155
+appropriate copyright notice and disclaimer of warranty; keep intact
156
+all the notices that refer to this License and to the absence of any
157
+warranty; and distribute a copy of this License along with the
158
+Library.
159
+
160
+You may charge a fee for the physical act of transferring a copy, and
161
+you may at your option offer warranty protection in exchange for a
162
+fee.
163
+
164
+**2.** You may modify your copy or copies of the Library or any
165
+portion of it, thus forming a work based on the Library, and copy and
166
+distribute such modifications or work under the terms of Section 1
167
+above, provided that you also meet all of these conditions:
168
+
169
+-   **a)** The modified work must itself be a software library.
170
+-   **b)** You must cause the files modified to carry prominent
171
+    notices stating that you changed the files and the date of
172
+    any change.
173
+-   **c)** You must cause the whole of the work to be licensed at no
174
+    charge to all third parties under the terms of this License.
175
+-   **d)** If a facility in the modified Library refers to a function
176
+    or a table of data to be supplied by an application program that
177
+    uses the facility, other than as an argument passed when the
178
+    facility is invoked, then you must make a good faith effort to
179
+    ensure that, in the event an application does not supply such
180
+    function or table, the facility still operates, and performs
181
+    whatever part of its purpose remains meaningful.
182
+
183
+    (For example, a function in a library to compute square roots has
184
+    a purpose that is entirely well-defined independent of
185
+    the application. Therefore, Subsection 2d requires that any
186
+    application-supplied function or table used by this function must
187
+    be optional: if the application does not supply it, the square
188
+    root function must still compute square roots.)
189
+
190
+These requirements apply to the modified work as a whole. If
191
+identifiable sections of that work are not derived from the Library,
192
+and can be reasonably considered independent and separate works in
193
+themselves, then this License, and its terms, do not apply to those
194
+sections when you distribute them as separate works. But when you
195
+distribute the same sections as part of a whole which is a work based
196
+on the Library, the distribution of the whole must be on the terms of
197
+this License, whose permissions for other licensees extend to the
198
+entire whole, and thus to each and every part regardless of who wrote
199
+it.
200
+
201
+Thus, it is not the intent of this section to claim rights or contest
202
+your rights to work written entirely by you; rather, the intent is to
203
+exercise the right to control the distribution of derivative or
204
+collective works based on the Library.
205
+
206
+In addition, mere aggregation of another work not based on the Library
207
+with the Library (or with a work based on the Library) on a volume of
208
+a storage or distribution medium does not bring the other work under
209
+the scope of this License.
210
+
211
+**3.** You may opt to apply the terms of the ordinary GNU General
212
+Public License instead of this License to a given copy of the Library.
213
+To do this, you must alter all the notices that refer to this License,
214
+so that they refer to the ordinary GNU General Public License, version
215
+2, instead of to this License. (If a newer version than version 2 of
216
+the ordinary GNU General Public License has appeared, then you can
217
+specify that version instead if you wish.) Do not make any other
218
+change in these notices.
219
+
220
+Once this change is made in a given copy, it is irreversible for that
221
+copy, so the ordinary GNU General Public License applies to all
222
+subsequent copies and derivative works made from that copy.
223
+
224
+This option is useful when you wish to copy part of the code of the
225
+Library into a program that is not a library.
226
+
227
+**4.** You may copy and distribute the Library (or a portion or
228
+derivative of it, under Section 2) in object code or executable form
229
+under the terms of Sections 1 and 2 above provided that you accompany
230
+it with the complete corresponding machine-readable source code, which
231
+must be distributed under the terms of Sections 1 and 2 above on a
232
+medium customarily used for software interchange.
233
+
234
+If distribution of object code is made by offering access to copy from
235
+a designated place, then offering equivalent access to copy the source
236
+code from the same place satisfies the requirement to distribute the
237
+source code, even though third parties are not compelled to copy the
238
+source along with the object code.
239
+
240
+**5.** A program that contains no derivative of any portion of the
241
+Library, but is designed to work with the Library by being compiled or
242
+linked with it, is called a "work that uses the Library". Such a work,
243
+in isolation, is not a derivative work of the Library, and therefore
244
+falls outside the scope of this License.
245
+
246
+However, linking a "work that uses the Library" with the Library
247
+creates an executable that is a derivative of the Library (because it
248
+contains portions of the Library), rather than a "work that uses the
249
+library". The executable is therefore covered by this License. Section
250
+6 states terms for distribution of such executables.
251
+
252
+When a "work that uses the Library" uses material from a header file
253
+that is part of the Library, the object code for the work may be a
254
+derivative work of the Library even though the source code is not.
255
+Whether this is true is especially significant if the work can be
256
+linked without the Library, or if the work is itself a library. The
257
+threshold for this to be true is not precisely defined by law.
258
+
259
+If such an object file uses only numerical parameters, data structure
260
+layouts and accessors, and small macros and small inline functions
261
+(ten lines or less in length), then the use of the object file is
262
+unrestricted, regardless of whether it is legally a derivative work.
263
+(Executables containing this object code plus portions of the Library
264
+will still fall under Section 6.)
265
+
266
+Otherwise, if the work is a derivative of the Library, you may
267
+distribute the object code for the work under the terms of Section 6.
268
+Any executables containing that work also fall under Section 6,
269
+whether or not they are linked directly with the Library itself.
270
+
271
+**6.** As an exception to the Sections above, you may also combine or
272
+link a "work that uses the Library" with the Library to produce a work
273
+containing portions of the Library, and distribute that work under
274
+terms of your choice, provided that the terms permit modification of
275
+the work for the customer's own use and reverse engineering for
276
+debugging such modifications.
277
+
278
+You must give prominent notice with each copy of the work that the
279
+Library is used in it and that the Library and its use are covered by
280
+this License. You must supply a copy of this License. If the work
281
+during execution displays copyright notices, you must include the
282
+copyright notice for the Library among them, as well as a reference
283
+directing the user to the copy of this License. Also, you must do one
284
+of these things:
285
+
286
+-   **a)** Accompany the work with the complete corresponding
287
+    machine-readable source code for the Library including whatever
288
+    changes were used in the work (which must be distributed under
289
+    Sections 1 and 2 above); and, if the work is an executable linked
290
+    with the Library, with the complete machine-readable "work that
291
+    uses the Library", as object code and/or source code, so that the
292
+    user can modify the Library and then relink to produce a modified
293
+    executable containing the modified Library. (It is understood that
294
+    the user who changes the contents of definitions files in the
295
+    Library will not necessarily be able to recompile the application
296
+    to use the modified definitions.)
297
+-   **b)** Use a suitable shared library mechanism for linking with
298
+    the Library. A suitable mechanism is one that (1) uses at run time
299
+    a copy of the library already present on the user's computer
300
+    system, rather than copying library functions into the executable,
301
+    and (2) will operate properly with a modified version of the
302
+    library, if the user installs one, as long as the modified version
303
+    is interface-compatible with the version that the work was
304
+    made with.
305
+-   **c)** Accompany the work with a written offer, valid for at least
306
+    three years, to give the same user the materials specified in
307
+    Subsection 6a, above, for a charge no more than the cost of
308
+    performing this distribution.
309
+-   **d)** If distribution of the work is made by offering access to
310
+    copy from a designated place, offer equivalent access to copy the
311
+    above specified materials from the same place.
312
+-   **e)** Verify that the user has already received a copy of these
313
+    materials or that you have already sent this user a copy.
314
+
315
+For an executable, the required form of the "work that uses the
316
+Library" must include any data and utility programs needed for
317
+reproducing the executable from it. However, as a special exception,
318
+the materials to be distributed need not include anything that is
319
+normally distributed (in either source or binary form) with the major
320
+components (compiler, kernel, and so on) of the operating system on
321
+which the executable runs, unless that component itself accompanies
322
+the executable.
323
+
324
+It may happen that this requirement contradicts the license
325
+restrictions of other proprietary libraries that do not normally
326
+accompany the operating system. Such a contradiction means you cannot
327
+use both them and the Library together in an executable that you
328
+distribute.
329
+
330
+**7.** You may place library facilities that are a work based on the
331
+Library side-by-side in a single library together with other library
332
+facilities not covered by this License, and distribute such a combined
333
+library, provided that the separate distribution of the work based on
334
+the Library and of the other library facilities is otherwise
335
+permitted, and provided that you do these two things:
336
+
337
+-   **a)** Accompany the combined library with a copy of the same work
338
+    based on the Library, uncombined with any other
339
+    library facilities. This must be distributed under the terms of
340
+    the Sections above.
341
+-   **b)** Give prominent notice with the combined library of the fact
342
+    that part of it is a work based on the Library, and explaining
343
+    where to find the accompanying uncombined form of the same work.
344
+
345
+**8.** You may not copy, modify, sublicense, link with, or distribute
346
+the Library except as expressly provided under this License. Any
347
+attempt otherwise to copy, modify, sublicense, link with, or
348
+distribute the Library is void, and will automatically terminate your
349
+rights under this License. However, parties who have received copies,
350
+or rights, from you under this License will not have their licenses
351
+terminated so long as such parties remain in full compliance.
352
+
353
+**9.** You are not required to accept this License, since you have not
354
+signed it. However, nothing else grants you permission to modify or
355
+distribute the Library or its derivative works. These actions are
356
+prohibited by law if you do not accept this License. Therefore, by
357
+modifying or distributing the Library (or any work based on the
358
+Library), you indicate your acceptance of this License to do so, and
359
+all its terms and conditions for copying, distributing or modifying
360
+the Library or works based on it.
361
+
362
+**10.** Each time you redistribute the Library (or any work based on
363
+the Library), the recipient automatically receives a license from the
364
+original licensor to copy, distribute, link with or modify the Library
365
+subject to these terms and conditions. You may not impose any further
366
+restrictions on the recipients' exercise of the rights granted herein.
367
+You are not responsible for enforcing compliance by third parties with
368
+this License.
369
+
370
+**11.** If, as a consequence of a court judgment or allegation of
371
+patent infringement or for any other reason (not limited to patent
372
+issues), conditions are imposed on you (whether by court order,
373
+agreement or otherwise) that contradict the conditions of this
374
+License, they do not excuse you from the conditions of this License.
375
+If you cannot distribute so as to satisfy simultaneously your
376
+obligations under this License and any other pertinent obligations,
377
+then as a consequence you may not distribute the Library at all. For
378
+example, if a patent license would not permit royalty-free
379
+redistribution of the Library by all those who receive copies directly
380
+or indirectly through you, then the only way you could satisfy both it
381
+and this License would be to refrain entirely from distribution of the
382
+Library.
383
+
384
+If any portion of this section is held invalid or unenforceable under
385
+any particular circumstance, the balance of the section is intended to
386
+apply, and the section as a whole is intended to apply in other
387
+circumstances.
388
+
389
+It is not the purpose of this section to induce you to infringe any
390
+patents or other property right claims or to contest validity of any
391
+such claims; this section has the sole purpose of protecting the
392
+integrity of the free software distribution system which is
393
+implemented by public license practices. Many people have made
394
+generous contributions to the wide range of software distributed
395
+through that system in reliance on consistent application of that
396
+system; it is up to the author/donor to decide if he or she is willing
397
+to distribute software through any other system and a licensee cannot
398
+impose that choice.
399
+
400
+This section is intended to make thoroughly clear what is believed to
401
+be a consequence of the rest of this License.
402
+
403
+**12.** If the distribution and/or use of the Library is restricted in
404
+certain countries either by patents or by copyrighted interfaces, the
405
+original copyright holder who places the Library under this License
406
+may add an explicit geographical distribution limitation excluding
407
+those countries, so that distribution is permitted only in or among
408
+countries not thus excluded. In such case, this License incorporates
409
+the limitation as if written in the body of this License.
410
+
411
+**13.** The Free Software Foundation may publish revised and/or new
412
+versions of the Lesser General Public License from time to time. Such
413
+new versions will be similar in spirit to the present version, but may
414
+differ in detail to address new problems or concerns.
415

+Each version is given a distinguishing version number. If the Library
417
+specifies a version number of this License which applies to it and
418
+"any later version", you have the option of following the terms and
419
+conditions either of that version or of any later version published by
420
+the Free Software Foundation. If the Library does not specify a
421
+license version number, you may choose any version ever published by
422
+the Free Software Foundation.
423
+
424
+**14.** If you wish to incorporate parts of the Library into other
425
+free programs whose distribution conditions are incompatible with
426
+these, write to the author to ask for permission. For software which
427
+is copyrighted by the Free Software Foundation, write to the Free
428
+Software Foundation; we sometimes make exceptions for this. Our
429
+decision will be guided by the two goals of preserving the free status
430
+of all derivatives of our free software and of promoting the sharing
431
+and reuse of software generally.
432
+
433
+**NO WARRANTY**
434
+
435
+**15.** BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
436
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
437
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
438
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
439
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
440

443
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
444

445
+**16.** IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

458
+### How to Apply These Terms to Your New Libraries
459
+
460
+If you develop a new library, and you want it to be of the greatest
461
+possible use to the public, we recommend making it free software that
462
+everyone can redistribute and change. You can do so by permitting
463
+redistribution under these terms (or, alternatively, under the terms
464
+of the ordinary General Public License).
465
+
466
+To apply these terms, attach the following notices to the library. It
467
+is safest to attach them to the start of each source file to most
468
+effectively convey the exclusion of warranty; and each file should
469
+have at least the "copyright" line and a pointer to where the full
470
+notice is found.
471
+
472
+    one line to give the library's name and an idea of what it does.
473
+    Copyright (C) year  name of author
474

475
+    This library is free software; you can redistribute it and/or
476
+    modify it under the terms of the GNU Lesser General Public

479
+
480
+    This library is distributed in the hope that it will be useful,
481
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
482
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
483
+    Lesser General Public License for more details.
484
+
485
+    You should have received a copy of the GNU Lesser General Public
486
+    License along with this library; if not, write to the Free Software
487
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
488
+
489
+Also add information on how to contact you by electronic and paper
490
+mail.
491
+
492
+You should also get your employer (if you work as a programmer) or
493
+your school, if any, to sign a "copyright disclaimer" for the library,
494
+if necessary. Here is a sample; alter the names:

+# =head1 OVERVIEW
40
+#
41
+# The workflow is following:
42
+#
43
+#  1. Per each upgrade path module, generate a pseudo-INI
44
+#     file, defining properties and content of the module.
45
+#
46
+#  2. Call preupg_fupath() to generate the
47
+#     upgrade path for you, using standard tools under the
48
+#     hood.
49
+#
50
+#  3. Call preupg (or better, preupg__run1()
51
+#     from preupgrade-assistant/main) to use the upgrade path.
52
+#
53
+#
54
+# =head1 FORMAT
55
+#
56
+# A fuller example:
57
+#
58
+#      [preupgrade]
59
+#      content_description = test module bob
60
+#      content_title = test module bob
61
+#
62
+#      [MODULE]
63
+#      GROUP = system
64
+#      NAME = foo
65
+#      LANG = sh
66
+#      CODE = log_medium_risk foo
67
+#      CODE = exit_pass
68
+#
69
+#      [FILES]
70
+#      solution.txt = Some text
71
+#      solution.txt = Some more text
72
+#      myfile.txt = first line of an arbitrary file
73
+#      myfile.txt = second line of of an arbitrary file
74
+#
75
+#  *  Fields from "preupgrade" section are directly copied to
76
+#     used the actual module.ini.
77
+#
78
+#  *  MODULE section should contain GROUP, NAME and a multi-line
79
+#     CODE of the module.  GROUP and NAME define placement of
80
+#     the module in the tree, CODE will be appended to the
81
+#     auto-generated script.
82
+#
83
+#     LANG key is 'sh' for Bash (default) and 'py' for Python.
84
+#
85
+#  *  FILES section can be used to include any number of plain
86
+#     text files (such as a hook scripts or config files) inside
87
+#     the module.   Here key name is name of the file and key
88
+#     content is content of the file.
89
+#
90
+# Virtually any field may be omitted; the generator will try to
91
+# fill in as much as possible (even generate names from random
92
+# chars).
93
+#
94
+# FILES section may be used to fully overwrite any other files
95
+# (even module.ini file!).  This is useful to test "extreme" cases such
96
+# as empty or malformed module.ini file, while retaining feature of
97
+# auto-generation mentioned above.
98
+#
99
+#
100
+# =head2 Indentation
101
+#
102
+# Multi-line values (CODE and values from FILES section) are
103
+# read in a way that preserves indentation by removing as many
104
+# spaces from first column as possible without removing other
105
+# characters.  For example, following sections:
106
+#
107
+#     CODE = def blah():
108
+#     CODE =   pass
109
+#     CODE =
110
+#     CODE = for p in get_dist_native_list():
111
+#     CODE =   blah()
112
+#
113
+#     CODE =     def blah():
114
+#     CODE =       pass
115
+#     CODE =
116
+#     CODE =     for p in get_dist_native_list():
117
+#     CODE =       blah()
118
+#
119
+#     CODE =def blah():
120
+#     CODE =  pass
121
+#     CODE =
122
+#     CODE =for p in get_dist_native_list():
123
+#     CODE =  blah()
124
+#
125
+# would result in exactly the same code:
126
+#
127
+#     def blah():
128
+#       pass
129
+#
130
+#     for p in get_dist_native_list():
131
+#       blah()
132
+#
133
+# This is in order to enable generation of valid Python scripts
134
+# while enabling maximum readability of your test code.

145

147

148
+    # Note: folders UPATH, UPATH-raw and UPATH-results in current
149
+    #       folder will be silently deleted!
150
+    #
151
+    #
152
+    # If FILE argument starts with "at sign" (`@`), it will be interpreted
153
+    # as name of a built-in .mdef file included within this library; look
154
+    # into "builtins" subfolder; the alias can be constructed as path
155
+    # to .mdef file relative to that folder, with .mdef suffix stripped.
156

157

158

159

+    # The version is compatible with SemVer 2.0.0.
