65
+ Installation
66
+ ============
67
+
68
+ Binary wheel install
69
+ --------------------
70
+
71
+ PyNaCl ships as a binary wheel on macOS, Windows and Linux ``manylinux1`` [#many]_ ,
72
+ so all dependencies are included. Make sure you have an up-to-date pip
73
+ and run:
74
+
75
+ .. code-block:: console
76
+
77
+ $ pip install pynacl
78
+
79
+ Faster wheel build
80
+ ------------------
81
+
82
+ You can define the environment variable ``LIBSODIUM_MAKE_ARGS`` to pass arguments to ``make``
83
+ and enable `parallelization`_:
84
+
85
+ .. code-block:: console
86
+
87
+ $ LIBSODIUM_MAKE_ARGS=-j4 pip install pynacl
88
+
89
+ Linux source build
90
+ ------------------
91
+
92
+ PyNaCl relies on `libsodium`_, a portable C library. A copy is bundled
93
+ with PyNaCl so to install you can run:
94
+
95
+ .. code-block:: console
96
+
97
+ $ pip install pynacl
98
+
99
+ If you'd prefer to use the version of ``libsodium`` provided by your
100
+ distribution, you can disable the bundled copy during install by running:
101
+
102
+ .. code-block:: console
103
+
104
+ $ SODIUM_INSTALL=system pip install pynacl
105
+
106
+ .. warning:: Usage of the legacy ``easy_install`` command provided by setuptools
107
+ is generally discouraged, and is completely unsupported in PyNaCl's case.
108
+
109
+ .. _parallelization: https://www.gnu.org/software/make/manual/html_node/Parallel.html
110
+
111
+ .. _libsodium: https://github.com/jedisct1/libsodium
112
+
113
+ .. [#many] `manylinux1 wheels <https://www.python.org/dev/peps/pep-0513/>`_
114
+ are built on a baseline linux environment based on Centos 5.11
115
+ and should work on most x86 and x86_64 glibc based linux environments.

117
+ Changelog
118
+ =========
119
+
120
+ 1.5.0 (2022-01-07)
121
+ ------------------
122
+
123
+ * **BACKWARDS INCOMPATIBLE:** Removed support for Python 2.7 and Python 3.5.
124
+ * **BACKWARDS INCOMPATIBLE:** We no longer distribute ``manylinux1``
125
+ wheels.
126
+ * Added ``manylinux2014``, ``manylinux_2_24``, ``musllinux``, and macOS
127
+ ``universal2`` wheels (the latter supports macOS ``arm64``).
128
+ * Update ``libsodium`` to 1.0.18-stable (July 25, 2021 release).
129
+ * Add inline type hints.
130
+
131
+ 1.4.0 (2020-05-25)
132
+ ------------------
133
+
134
+ * Update ``libsodium`` to 1.0.18.
135
+ * **BACKWARDS INCOMPATIBLE:** We no longer distribute 32-bit ``manylinux1``
136
+ wheels. Continuing to produce them was a maintenance burden.
137
+ * Added support for Python 3.8, and removed support for Python 3.4.
138
+ * Add low level bindings for extracting the seed and the public key
139
+ from crypto_sign_ed25519 secret key
140
+ * Add low level bindings for deterministic random generation.
141
+ * Add ``wheel`` and ``setuptools`` setup_requirements in ``setup.py`` (#485)
142
+ * Fix checks on very slow builders (#481, #495)
143
+ * Add low-level bindings to ed25519 arithmetic functions
144
+ * Update low-level blake2b state implementation
145
+ * Fix wrong short-input behavior of SealedBox.decrypt() (#517)
146
+ * Raise CryptPrefixError exception instead of InvalidkeyError when trying
147
+ to check a password against a verifier stored in a unknown format (#519)
148
+ * Add support for minimal builds of libsodium. Trying to call functions
149
+ not available in a minimal build will raise an UnavailableError
150
+ exception. To compile a minimal build of the bundled libsodium, set
151
+ the SODIUM_INSTALL_MINIMAL environment variable to any non-empty
152
+ string (e.g. ``SODIUM_INSTALL_MINIMAL=1``) for setup.
153
+
154
+ 1.3.0 2018-09-26
155
+ ----------------
156
+
157
+ * Added support for Python 3.7.
158
+ * Update ``libsodium`` to 1.0.16.
159
+ * Run and test all code examples in PyNaCl docs through sphinx's
160
+ doctest builder.
161
+ * Add low-level bindings for chacha20-poly1305 AEAD constructions.
162
+ * Add low-level bindings for the chacha20-poly1305 secretstream constructions.
163
+ * Add low-level bindings for ed25519ph pre-hashed signing construction.
164
+ * Add low-level bindings for constant-time increment and addition
165
+ on fixed-precision big integers represented as little-endian
166
+ byte sequences.
167
+ * Add low-level bindings for the ISO/IEC 7816-4 compatible padding API.
168
+ * Add low-level bindings for libsodium's crypto_kx... key exchange
169
+ construction.
170
+ * Set hypothesis deadline to None in tests/test_pwhash.py to avoid
171
+ incorrect test failures on slower processor architectures. GitHub
172
+ issue #370
173
+
174
+ 1.2.1 - 2017-12-04
175
+ ------------------
176
+
177
+ * Update hypothesis minimum allowed version.
178
+ * Infrastructure: add proper configuration for readthedocs builder
179
+ runtime environment.
180
+
181
+ 1.2.0 - 2017-11-01
182
+ ------------------
183
+
184
+ * Update ``libsodium`` to 1.0.15.
185
+ * Infrastructure: add jenkins support for automatic build of
186
+ ``manylinux1`` binary wheels
187
+ * Added support for ``SealedBox`` construction.
188
+ * Added support for ``argon2i`` and ``argon2id`` password hashing constructs
189
+ and restructured high-level password hashing implementation to expose
190
+ the same interface for all hashers.
191
+ * Added support for 128 bit ``siphashx24`` variant of ``siphash24``.
192
+ * Added support for ``from_seed`` APIs for X25519 keypair generation.
193
+ * Dropped support for Python 3.3.
194
+
195
+ 1.1.2 - 2017-03-31
196
+ ------------------
197
+
198
+ * reorder link time library search path when using bundled
199
+ libsodium
200
+
201
+ 1.1.1 - 2017-03-15
202
+ ------------------
203
+
204
+ * Fixed a circular import bug in ``nacl.utils``.
205
+
206
+ 1.1.0 - 2017-03-14
207
+ ------------------
208
+
209
+ * Dropped support for Python 2.6.
210
+ * Added ``shared_key()`` method on ``Box``.
211
+ * You can now pass ``None`` to ``nonce`` when encrypting with ``Box`` or
212
+ ``SecretBox`` and it will automatically generate a random nonce.
213
+ * Added support for ``siphash24``.
214
+ * Added support for ``blake2b``.
215
+ * Added support for ``scrypt``.
216
+ * Update ``libsodium`` to 1.0.11.
217
+ * Default to the bundled ``libsodium`` when compiling.
218
+ * All raised exceptions are defined mixing-in
219
+ ``nacl.exceptions.CryptoError``
220
+
221
+ 1.0.1 - 2016-01-24
222
+ ------------------
223
+
224
+ * Fix an issue with absolute paths that prevented the creation of wheels.
225
+
226
+ 1.0 - 2016-01-23
227
+ ----------------
228
+
229
+ * PyNaCl has been ported to use the new APIs available in cffi 1.0+.
230
+ Due to this change we no longer support PyPy releases older than 2.6.
231
+ * Python 3.2 support has been dropped.
232
+ * Functions to convert between Ed25519 and Curve25519 keys have been added.
233
+
234
+ 0.3.0 - 2015-03-04
235
+ ------------------
236
+
237
+ * The low-level API (`nacl.c.*`) has been changed to match the
238
+ upstream NaCl C/C++ conventions (as well as those of other NaCl bindings).
239
+ The order of arguments and return values has changed significantly. To
240
+ avoid silent failures, `nacl.c` has been removed, and replaced with
241
+ `nacl.bindings` (with the new argument ordering). If you have code which
242
+ calls these functions (e.g. `nacl.c.crypto_box_keypair()`), you must review
243
+ the new docstrings and update your code/imports to match the new
244
+ conventions.

103
+ The Python SQL Toolkit and Object Relational Mapper
104
+
105
+ Introduction
106
+ -------------
107
+
108
+ SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
109
+ that gives application developers the full power and
110
+ flexibility of SQL. SQLAlchemy provides a full suite
111
+ of well known enterprise-level persistence patterns,
112
+ designed for efficient and high-performing database
113
+ access, adapted into a simple and Pythonic domain
114
+ language.
115
+
116
+ Major SQLAlchemy features include:
117
+
118
+ * An industrial strength ORM, built
119
+ from the core on the identity map, unit of work,
120
+ and data mapper patterns. These patterns
121
+ allow transparent persistence of objects
122
+ using a declarative configuration system.
123
+ Domain models
124
+ can be constructed and manipulated naturally,
125
+ and changes are synchronized with the
126
+ current transaction automatically.
127
+ * A relationally-oriented query system, exposing
128
+ the full range of SQL's capabilities
129
+ explicitly, including joins, subqueries,
130
+ correlation, and most everything else,
131
+ in terms of the object model.
132
+ Writing queries with the ORM uses the same
133
+ techniques of relational composition you use
134
+ when writing SQL. While you can drop into
135
+ literal SQL at any time, it's virtually never
136
+ needed.
137
+ * A comprehensive and flexible system
138
+ of eager loading for related collections and objects.
139
+ Collections are cached within a session,
140
+ and can be loaded on individual access, all
141
+ at once using joins, or by query per collection
142
+ across the full result set.
143
+ * A Core SQL construction system and DBAPI
144
+ interaction layer. The SQLAlchemy Core is
145
+ separate from the ORM and is a full database
146
+ abstraction layer in its own right, and includes
147
+ an extensible Python-based SQL expression
148
+ language, schema metadata, connection pooling,
149
+ type coercion, and custom types.
150
+ * All primary and foreign key constraints are
151
+ assumed to be composite and natural. Surrogate
152
+ integer primary keys are of course still the
153
+ norm, but SQLAlchemy never assumes or hardcodes
154
+ to this model.
155
+ * Database introspection and generation. Database
156
+ schemas can be "reflected" in one step into
157
+ Python structures representing database metadata;
158
+ those same structures can then generate
159
+ CREATE statements right back out - all within
160
+ the Core, independent of the ORM.
161
+
162
+ SQLAlchemy's philosophy:
163
+
164
+ * SQL databases behave less and less like object
165
+ collections the more size and performance start to
166
+ matter; object collections behave less and less like
167
+ tables and rows the more abstraction starts to matter.
168
+ SQLAlchemy aims to accommodate both of these
169
+ principles.
170
+ * An ORM doesn't need to hide the "R". A relational
171
+ database provides rich, set-based functionality
172
+ that should be fully exposed. SQLAlchemy's
173
+ ORM provides an open-ended set of patterns
174
+ that allow a developer to construct a custom
175
+ mediation layer between a domain model and
176
+ a relational schema, turning the so-called
177
+ "object relational impedance" issue into
178
+ a distant memory.
179
+ * The developer, in all cases, makes all decisions
180
+ regarding the design, structure, and naming conventions
181
+ of both the object model as well as the relational
182
+ schema. SQLAlchemy only provides the means
183
+ to automate the execution of these decisions.
184
+ * With SQLAlchemy, there's no such thing as
185
+ "the ORM generated a bad query" - you
186
+ retain full control over the structure of
187
+ queries, including how joins are organized,
188
+ how subqueries and correlation is used, what
189
+ columns are requested. Everything SQLAlchemy
190
+ does is ultimately the result of a developer-initiated
191
+ decision.
192
+ * Don't use an ORM if the problem doesn't need one.
193
+ SQLAlchemy consists of a Core and separate ORM
194
+ component. The Core offers a full SQL expression
195
+ language that allows Pythonic construction
196
+ of SQL constructs that render directly to SQL
197
+ strings for a target database, returning
198
+ result sets that are essentially enhanced DBAPI
199
+ cursors.
200
+ * Transactions should be the norm. With SQLAlchemy's
201
+ ORM, nothing goes to permanent storage until
202
+ commit() is called. SQLAlchemy encourages applications
203
+ to create a consistent means of delineating
204
+ the start and end of a series of operations.
205
+ * Never render a literal value in a SQL statement.
206
+ Bound parameters are used to the greatest degree
207
+ possible, allowing query optimizers to cache
208
+ query plans effectively and making SQL injection
209
+ attacks a non-issue.

+ GNU LESSER GENERAL PUBLIC LICENSE
2
+ Version 3, 29 June 2007
3
+
4
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
5
+ Everyone is permitted to copy and distribute verbatim copies
6
+ of this license document, but changing it is not allowed.
7
+
8
+
9
+ This version of the GNU Lesser General Public License incorporates
10
+ the terms and conditions of version 3 of the GNU General Public
11
+ License, supplemented by the additional permissions listed below.
12
+
13
+ 0. Additional Definitions.
14
+
15
+ As used herein, "this License" refers to version 3 of the GNU Lesser
16
+ General Public License, and the "GNU GPL" refers to version 3 of the GNU
17
+ General Public License.
18
+
19
+ "The Library" refers to a covered work governed by this License,
20
+ other than an Application or a Combined Work as defined below.
21
+
22
+ An "Application" is any work that makes use of an interface provided
23
+ by the Library, but which is not otherwise based on the Library.
24
+ Defining a subclass of a class defined by the Library is deemed a mode
25
+ of using an interface provided by the Library.
26
+
27
+ A "Combined Work" is a work produced by combining or linking an
28
+ Application with the Library. The particular version of the Library
29
+ with which the Combined Work was made is also called the "Linked
30
+ Version".
31
+
32
+ The "Minimal Corresponding Source" for a Combined Work means the
33
+ Corresponding Source for the Combined Work, excluding any source code
34
+ for portions of the Combined Work that, considered in isolation, are
35
+ based on the Application, and not on the Linked Version.
36
+
37
+ The "Corresponding Application Code" for a Combined Work means the
38
+ object code and/or source code for the Application, including any data
39
+ and utility programs needed for reproducing the Combined Work from the
40
+ Application, but excluding the System Libraries of the Combined Work.
41
+
42
+ 1. Exception to Section 3 of the GNU GPL.
43
+
44
+ You may convey a covered work under sections 3 and 4 of this License
45
+ without being bound by section 3 of the GNU GPL.
46
+
47
+ 2. Conveying Modified Versions.
48
+
49
+ If you modify a copy of the Library, and, in your modifications, a
50
+ facility refers to a function or data to be supplied by an Application
51
+ that uses the facility (other than as an argument passed when the
52
+ facility is invoked), then you may convey a copy of the modified
53
+ version:
54
+
55
+ a) under this License, provided that you make a good faith effort to
56
+ ensure that, in the event an Application does not supply the
57
+ function or data, the facility still operates, and performs
58
+ whatever part of its purpose remains meaningful, or
59
+
60
+ b) under the GNU GPL, with none of the additional permissions of
61
+ this License applicable to that copy.
62
+
63
+ 3. Object Code Incorporating Material from Library Header Files.
64
+
65
+ The object code form of an Application may incorporate material from
66
+ a header file that is part of the Library. You may convey such object
67
+ code under terms of your choice, provided that, if the incorporated
68
+ material is not limited to numerical parameters, data structure
69
+ layouts and accessors, or small macros, inline functions and templates
70
+ (ten or fewer lines in length), you do both of the following:
71
+
72
+ a) Give prominent notice with each copy of the object code that the
73
+ Library is used in it and that the Library and its use are
74
+ covered by this License.
75
+
76
+ b) Accompany the object code with a copy of the GNU GPL and this license
77
+ document.
78
+
79
+ 4. Combined Works.
80
+
81
+ You may convey a Combined Work under terms of your choice that,
82
+ taken together, effectively do not restrict modification of the
83
+ portions of the Library contained in the Combined Work and reverse
84
+ engineering for debugging such modifications, if you also do each of
85
+ the following:
86
+
87
+ a) Give prominent notice with each copy of the Combined Work that
88
+ the Library is used in it and that the Library and its use are
89
+ covered by this License.
90
+
91
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
92
+ document.
93
+
94
+ c) For a Combined Work that displays copyright notices during
95
+ execution, include the copyright notice for the Library among
96
+ these notices, as well as a reference directing the user to the
97
+ copies of the GNU GPL and this license document.
98
+
99
+ d) Do one of the following:
100
+
101
+ 0) Convey the Minimal Corresponding Source under the terms of this
102
+ License, and the Corresponding Application Code in a form
103
+ suitable for, and under terms that permit, the user to
104
+ recombine or relink the Application with a modified version of
105
+ the Linked Version to produce a modified Combined Work, in the
106
+ manner specified by section 6 of the GNU GPL for conveying
107
+ Corresponding Source.
108
+
109
+ 1) Use a suitable shared library mechanism for linking with the
110
+ Library. A suitable mechanism is one that (a) uses at run time
111
+ a copy of the Library already present on the user's computer
112
+ system, and (b) will operate properly with a modified version
113
+ of the Library that is interface-compatible with the Linked
114
+ Version.
115
+
116
+ e) Provide Installation Information, but only if you would otherwise
117
+ be required to provide such information under section 6 of the
118
+ GNU GPL, and only to the extent that such information is
119
+ necessary to install and execute a modified version of the
120
+ Combined Work produced by recombining or relinking the
121
+ Application with a modified version of the Linked Version. (If
122
+ you use option 4d0, the Installation Information must accompany
123
+ the Minimal Corresponding Source and Corresponding Application
124
+ Code. If you use option 4d1, you must provide the Installation
125
+ Information in the manner specified by section 6 of the GNU GPL
126
+ for conveying Corresponding Source.)
127
+
128
+ 5. Combined Libraries.
129
+
130
+ You may place library facilities that are a work based on the
131
+ Library side by side in a single library together with other library
132
+ facilities that are not Applications and are not covered by this
133
+ License, and convey such a combined library under terms of your
134
+ choice, if you do both of the following:
135
+
136
+ a) Accompany the combined library with a copy of the same work based
137
+ on the Library, uncombined with any other library facilities,
138
+ conveyed under the terms of this License.
139
+
140
+ b) Give prominent notice with the combined library that part of it
141
+ is a work based on the Library, and explaining where to find the
142
+ accompanying uncombined form of the same work.
143
+
144
+ 6. Revised Versions of the GNU Lesser General Public License.
145
+
146
+ The Free Software Foundation may publish revised and/or new versions
147
+ of the GNU Lesser General Public License from time to time. Such new
148
+ versions will be similar in spirit to the present version, but may
149
+ differ in detail to address new problems or concerns.
150
+
151
+ Each version is given a distinguishing version number. If the
152
+ Library as you received it specifies that a certain numbered version
153
+ of the GNU Lesser General Public License "or any later version"
154
+ applies to it, you have the option of following the terms and
155
+ conditions either of that published version or of any later version
156
+ published by the Free Software Foundation. If the Library as you
157
+ received it does not specify a version number of the GNU Lesser
158
+ General Public License, you may choose any version of the GNU Lesser
159
+ General Public License ever published by the Free Software Foundation.
160
+
161
+ If the Library as you received it specifies that a proxy can decide
162
+ whether future versions of the GNU Lesser General Public License shall
163
+ apply, that proxy's public statement of acceptance of any version is
164
+ permanent authorization for you to choose that version for the
165
+ Library.

25
+ Establish how types should be converted between Python and PostgreSQL in
26

27
+
28
+ `!AdaptersMap` maps Python types to `~psycopg.adapt.Dumper` classes to
29
+ define how Python types are converted to PostgreSQL, and maps OIDs to
30
+ `~psycopg.adapt.Loader` classes to establish how query results are
31
+ converted to Python.
32
+
33
+ Every `!AdaptContext` object has an underlying `!AdaptersMap` defining how
34
+ types are converted in that context, exposed as the
35
+ `~psycopg.abc.AdaptContext.adapters` attribute: changing such map allows
36
+ to customise adaptation in a context without changing separated contexts.
37
+
38
+ When a context is created from another context (for instance when a
39
+ `~psycopg.Cursor` is created from a `~psycopg.Connection`), the parent's
40
+ `!adapters` are used as template for the child's `!adapters`, so that every
41
+ cursor created from the same connection use the connection's types
42
+ configuration, but separate connections have independent mappings.
43
+
44
+ Once created, `!AdaptersMap` are independent. This means that objects
45
+ already created are not affected if a wider scope (e.g. the global one) is
46
+ changed.
47
+
48
+ The connections adapters are initialised using a global `!AdptersMap`
49
+ template, exposed as `psycopg.adapters`: changing such mapping allows to
50
+ customise the type mapping for every connections created afterwards.
51
+
52
+ The object can start empty or copy from another object of the same class.
53
+ Copies are copy-on-write: if the maps are updated make a copy. This way
54
+ extending e.g. global map by a connection or a connection map from a cursor
55
+ is cheap: a copy is only made on customisation.

19

29

30
+ Version".
31
+
32
+ The "Minimal Corresponding Source" for a Combined Work means the
33
+ Corresponding Source for the Combined Work, excluding any source code
34

37
+ The "Corresponding Application Code" for a Combined Work means the
38
+ object code and/or source code for the Application, including any data
39
+ and utility programs needed for reproducing the Combined Work from the
40
+ Application, but excluding the System Libraries of the Combined Work.
41
+
42
+ 1. Exception to Section 3 of the GNU GPL.
43
+
44
+ You may convey a covered work under sections 3 and 4 of this License
45
+ without being bound by section 3 of the GNU GPL.
46
+
47
+ 2. Conveying Modified Versions.
48
+
49
+ If you modify a copy of the Library, and, in your modifications, a
50
+ facility refers to a function or data to be supplied by an Application
51
+ that uses the facility (other than as an argument passed when the
52
+ facility is invoked), then you may convey a copy of the modified
53
+ version:
54
+
55
+ a) under this License, provided that you make a good faith effort to
56
+ ensure that, in the event an Application does not supply the
57
+ function or data, the facility still operates, and performs
58
+ whatever part of its purpose remains meaningful, or
59
+
60
+ b) under the GNU GPL, with none of the additional permissions of
61
+ this License applicable to that copy.
62
+
63
+ 3. Object Code Incorporating Material from Library Header Files.
64
+
65
+ The object code form of an Application may incorporate material from
66
+ a header file that is part of the Library. You may convey such object
67
+ code under terms of your choice, provided that, if the incorporated
68
+ material is not limited to numerical parameters, data structure
69
+ layouts and accessors, or small macros, inline functions and templates
70
+ (ten or fewer lines in length), you do both of the following:
71
+
72
+ a) Give prominent notice with each copy of the object code that the
73
+ Library is used in it and that the Library and its use are
74
+ covered by this License.
75
+
76
+ b) Accompany the object code with a copy of the GNU GPL and this license
77
+ document.
78
+
79
+ 4. Combined Works.
80
+
81
+ You may convey a Combined Work under terms of your choice that,
82
+ taken together, effectively do not restrict modification of the
83
+ portions of the Library contained in the Combined Work and reverse
84
+ engineering for debugging such modifications, if you also do each of
85
+ the following:
86
+
87
+ a) Give prominent notice with each copy of the Combined Work that
88
+ the Library is used in it and that the Library and its use are
89
+ covered by this License.
90
+
91
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
92
+ document.
93
+
94
+ c) For a Combined Work that displays copyright notices during
95
+ execution, include the copyright notice for the Library among
96
+ these notices, as well as a reference directing the user to the
97
+ copies of the GNU GPL and this license document.
98
+
99
+ d) Do one of the following:
100
+
101
+ 0) Convey the Minimal Corresponding Source under the terms of this
102
+ License, and the Corresponding Application Code in a form
103
+ suitable for, and under terms that permit, the user to
104
+ recombine or relink the Application with a modified version of
105
+ the Linked Version to produce a modified Combined Work, in the
106
+ manner specified by section 6 of the GNU GPL for conveying
107
+ Corresponding Source.
108
+
109
+ 1) Use a suitable shared library mechanism for linking with the
110
+ Library. A suitable mechanism is one that (a) uses at run time
111
+ a copy of the Library already present on the user's computer
112
+ system, and (b) will operate properly with a modified version
113
+ of the Library that is interface-compatible with the Linked
114
+ Version.
115
+
116
+ e) Provide Installation Information, but only if you would otherwise
117
+ be required to provide such information under section 6 of the
118
+ GNU GPL, and only to the extent that such information is
119
+ necessary to install and execute a modified version of the
120
+ Combined Work produced by recombining or relinking the
121
+ Application with a modified version of the Linked Version. (If
122
+ you use option 4d0, the Installation Information must accompany
123
+ the Minimal Corresponding Source and Corresponding Application
124
+ Code. If you use option 4d1, you must provide the Installation
125
+ Information in the manner specified by section 6 of the GNU GPL
126
+ for conveying Corresponding Source.)
127
+
128
+ 5. Combined Libraries.
129
+
130
+ You may place library facilities that are a work based on the
131
+ Library side by side in a single library together with other library
132
+ facilities that are not Applications and are not covered by this
133
+ License, and convey such a combined library under terms of your
134
+ choice, if you do both of the following:
135
+
136
+ a) Accompany the combined library with a copy of the same work based
137
+ on the Library, uncombined with any other library facilities,
138
+ conveyed under the terms of this License.
139
+
140
+ b) Give prominent notice with the combined library that part of it
141
+ is a work based on the Library, and explaining where to find the
142
+ accompanying uncombined form of the same work.
143
+
144
+ 6. Revised Versions of the GNU Lesser General Public License.
145
+
146
+ The Free Software Foundation may publish revised and/or new versions
147
+ of the GNU Lesser General Public License from time to time. Such new
148
+ versions will be similar in spirit to the present version, but may
149
+ differ in detail to address new problems or concerns.
150
+
151
+ Each version is given a distinguishing version number. If the
152
+ Library as you received it specifies that a certain numbered version
153
+ of the GNU Lesser General Public License "or any later version"
154
+ applies to it, you have the option of following the terms and
155
+ conditions either of that published version or of any later version
156
+ published by the Free Software Foundation. If the Library as you
157
+ received it does not specify a version number of the GNU Lesser
158
+ General Public License, you may choose any version of the GNU Lesser
159
+ General Public License ever published by the Free Software Foundation.
160
+
161
+ If the Library as you received it specifies that a proxy can decide
162
+ whether future versions of the GNU Lesser General Public License shall
163
+ apply, that proxy's public statement of acceptance of any version is
164
+ permanent authorization for you to choose that version for the
165
+ Library.
