   23: @appendixsubsec Preamble
   24: 
   25:   The licenses for most software are designed to take away your
   26: freedom to share and change it.  By contrast, the GNU General Public
   27: Licenses are intended to guarantee your freedom to share and change
   28: free software---to make sure the software is free for all its users.
   29: 
   30:   This license, the Lesser General Public License, applies to some
   31: specially designated software---typically libraries---of the Free
   32: Software Foundation and other authors who decide to use it.  You can use
   33: it too, but we suggest you first think carefully about whether this
   34: license or the ordinary General Public License is the better strategy to
   35: use in any particular case, based on the explanations below.
   36: 
   37:   When we speak of free software, we are referring to freedom of use,
   38: not price.  Our General Public Licenses are designed to make sure that
   39: you have the freedom to distribute copies of free software (and charge
   40: for this service if you wish); that you receive source code or can get
   41: it if you want it; that you can change the software and use pieces of it
   42: in new free programs; and that you are informed that you can do these
   43: things.
   44: 
   45:   To protect your rights, we need to make restrictions that forbid
   46: distributors to deny you these rights or to ask you to surrender these
   47: rights.  These restrictions translate to certain responsibilities for
   48: you if you distribute copies of the library or if you modify it.
   49: 
   50:   For example, if you distribute copies of the library, whether gratis
   51: or for a fee, you must give the recipients all the rights that we gave
   52: you.  You must make sure that they, too, receive or can get the source
   53: code.  If you link other code with the library, you must provide
   54: complete object files to the recipients, so that they can relink them
   55: with the library after making changes to the library and recompiling
   56: it.  And you must show them these terms so they know their rights.
   57: 
   58:   We protect your rights with a two-step method: (1) we copyright the
   59: library, and (2) we offer you this license, which gives you legal
   60: permission to copy, distribute and/or modify the library.
   61: 
   62:   To protect each distributor, we want to make it very clear that
   63: there is no warranty for the free library.  Also, if the library is
   64: modified by someone else and passed on, the recipients should know
   65: that what they have is not the original version, so that the original
   66: author's reputation will not be affected by problems that might be
   67: introduced by others.
   68: 
   69:   Finally, software patents pose a constant threat to the existence of
   70: any free program.  We wish to make sure that a company cannot
   71: effectively restrict the users of a free program by obtaining a
   72: restrictive license from a patent holder.  Therefore, we insist that
   73: any patent license obtained for a version of the library must be
   74: consistent with the full freedom of use specified in this license.
   75: 
   76:   Most GNU software, including some libraries, is covered by the
   77: ordinary GNU General Public License.  This license, the GNU Lesser
   78: General Public License, applies to certain designated libraries, and
   79: is quite different from the ordinary General Public License.  We use
   80: this license for certain libraries in order to permit linking those
   81: libraries into non-free programs.
   82: 
   83:   When a program is linked with a library, whether statically or using
   84: a shared library, the combination of the two is legally speaking a
   85: combined work, a derivative of the original library.  The ordinary
   86: General Public License therefore permits such linking only if the
   87: entire combination fits its criteria of freedom.  The Lesser General
   88: Public License permits more lax criteria for linking other code with
   89: the library.
   90: 
   91:   We call this license the @dfn{Lesser} General Public License because it
   92: does @emph{Less} to protect the user's freedom than the ordinary General
   93: Public License.  It also provides other free software developers Less
   94: of an advantage over competing non-free programs.  These disadvantages
   95: are the reason we use the ordinary General Public License for many
   96: libraries.  However, the Lesser license provides advantages in certain
   97: special circumstances.
   98: 
   99:   For example, on rare occasions, there may be a special need to
  100: encourage the widest possible use of a certain library, so that it becomes
  101: a de-facto standard.  To achieve this, non-free programs must be
  102: allowed to use the library.  A more frequent case is that a free
  103: library does the same job as widely used non-free libraries.  In this
  104: case, there is little to gain by limiting the free library to free
  105: software only, so we use the Lesser General Public License.
  106: 
  107:   In other cases, permission to use a particular library in non-free
  108: programs enables a greater number of people to use a large body of
  109: free software.  For example, permission to use the GNU C Library in
  110: non-free programs enables many more people to use the whole GNU
  111: operating system, as well as its variant, the GNU/Linux operating
  112: system.
  113: 
  114:   Although the Lesser General Public License is Less protective of the
  115: users' freedom, it does ensure that the user of a program that is
  116: linked with the Library has the freedom and the wherewithal to run
  117: that program using a modified version of the Library.
  118: 
  119:   The precise terms and conditions for copying, distribution and
  120: modification follow.  Pay close attention to the difference between a
  121: ``work based on the library'' and a ``work that uses the library''.  The
  122: former contains code derived from the library, whereas the latter must
  123: be combined with the library in order to run.

  134: @item
  135: This License Agreement applies to any software library or other program
  136: which contains a notice placed by the copyright holder or other
  137: authorized party saying it may be distributed under the terms of this
  138: Lesser General Public License (also called ``this License'').  Each
  139: licensee is addressed as ``you''.
  140: 
  141:   A ``library'' means a collection of software functions and/or data
  142: prepared so as to be conveniently linked with application programs
  143: (which use some of those functions and data) to form executables.
  144: 
  145:   The ``Library'', below, refers to any such software library or work
  146: which has been distributed under these terms.  A ``work based on the
  147: Library'' means either the Library or any derivative work under
  148: copyright law: that is to say, a work containing the Library or a
  149: portion of it, either verbatim or with modifications and/or translated
  150: straightforwardly into another language.  (Hereinafter, translation is
  151: included without limitation in the term ``modification''.)
  152: 
  153:   ``Source code'' for a work means the preferred form of the work for
  154: making modifications to it.  For a library, complete source code means
  155: all the source code for all modules it contains, plus any associated
  156: interface definition files, plus the scripts used to control compilation
  157: and installation of the library.
  158: 
  159:   Activities other than copying, distribution and modification are not
  160: covered by this License; they are outside its scope.  The act of
  161: running a program using the Library is not restricted, and output from
  162: such a program is covered only if its contents constitute a work based
  163: on the Library (independent of the use of the Library in a tool for
  164: writing it).  Whether that is true depends on what the Library does
  165: and what the program that uses the Library does.
  166: 
  167: @item
  168: You may copy and distribute verbatim copies of the Library's
  169: complete source code as you receive it, in any medium, provided that
  170: you conspicuously and appropriately publish on each copy an
  171: appropriate copyright notice and disclaimer of warranty; keep intact
  172: all the notices that refer to this License and to the absence of any
  173: warranty; and distribute a copy of this License along with the
  174: Library.
  175: 
  176:   You may charge a fee for the physical act of transferring a copy,
  177: and you may at your option offer warranty protection in exchange for a
  178: fee.
  179: 
  180: @item
  181: You may modify your copy or copies of the Library or any portion
  182: of it, thus forming a work based on the Library, and copy and
  183: distribute such modifications or work under the terms of Section 1
  184: above, provided that you also meet all of these conditions:
  185: 
  186: @enumerate a
  187: @item
  188: The modified work must itself be a software library.
  189: 
  190: @item
  191: You must cause the files modified to carry prominent notices
  192: stating that you changed the files and the date of any change.
  193: 
  194: @item
  195: You must cause the whole of the work to be licensed at no
  196: charge to all third parties under the terms of this License.
  197: 
  198: @item
  199: If a facility in the modified Library refers to a function or a
  200: table of data to be supplied by an application program that uses
  201: the facility, other than as an argument passed when the facility
  202: is invoked, then you must make a good faith effort to ensure that,
  203: in the event an application does not supply such function or
  204: table, the facility still operates, and performs whatever part of
  205: its purpose remains meaningful.
  206: 
  207: (For example, a function in a library to compute square roots has
  208: a purpose that is entirely well-defined independent of the
  209: application.  Therefore, Subsection 2d requires that any
  210: application-supplied function or table used by this function must
  211: be optional: if the application does not supply it, the square
  212: root function must still compute square roots.)
  213: @end enumerate
  214: 
  215: These requirements apply to the modified work as a whole.  If
  216: identifiable sections of that work are not derived from the Library,
  217: and can be reasonably considered independent and separate works in
  218: themselves, then this License, and its terms, do not apply to those
  219: sections when you distribute them as separate works.  But when you
  220: distribute the same sections as part of a whole which is a work based
  221: on the Library, the distribution of the whole must be on the terms of
  222: this License, whose permissions for other licensees extend to the
  223: entire whole, and thus to each and every part regardless of who wrote
  224: it.
  225: 
  226: Thus, it is not the intent of this section to claim rights or contest
  227: your rights to work written entirely by you; rather, the intent is to
  228: exercise the right to control the distribution of derivative or
  229: collective works based on the Library.
  230: 
  231: In addition, mere aggregation of another work not based on the Library
  232: with the Library (or with a work based on the Library) on a volume of
  233: a storage or distribution medium does not bring the other work under
  234: the scope of this License.
  235: 
  236: @item
  237: You may opt to apply the terms of the ordinary GNU General Public
  238: License instead of this License to a given copy of the Library.  To do
  239: this, you must alter all the notices that refer to this License, so
  240: that they refer to the ordinary GNU General Public License, version 2,
  241: instead of to this License.  (If a newer version than version 2 of the
  242: ordinary GNU General Public License has appeared, then you can specify
  243: that version instead if you wish.)  Do not make any other change in
  244: these notices.
  245: 
  246:   Once this change is made in a given copy, it is irreversible for
  247: that copy, so the ordinary GNU General Public License applies to all
  248: subsequent copies and derivative works made from that copy.
  249: 
  250:   This option is useful when you wish to copy part of the code of
  251: the Library into a program that is not a library.
  252: 
  253: @item
  254: You may copy and distribute the Library (or a portion or
  255: derivative of it, under Section 2) in object code or executable form
  256: under the terms of Sections 1 and 2 above provided that you accompany
  257: it with the complete corresponding machine-readable source code, which
  258: must be distributed under the terms of Sections 1 and 2 above on a
  259: medium customarily used for software interchange.
  260: 
  261:   If distribution of object code is made by offering access to copy
  262: from a designated place, then offering equivalent access to copy the
  263: source code from the same place satisfies the requirement to
  264: distribute the source code, even though third parties are not
  265: compelled to copy the source along with the object code.
  266: 
  267: @item
  268: A program that contains no derivative of any portion of the
  269: Library, but is designed to work with the Library by being compiled or
  270: linked with it, is called a ``work that uses the Library''.  Such a
  271: work, in isolation, is not a derivative work of the Library, and
  272: therefore falls outside the scope of this License.
  273: 
  274:   However, linking a ``work that uses the Library'' with the Library
  275: creates an executable that is a derivative of the Library (because it
  276: contains portions of the Library), rather than a ``work that uses the
  277: library''.  The executable is therefore covered by this License.
  278: Section 6 states terms for distribution of such executables.
  279: 
  280:   When a ``work that uses the Library'' uses material from a header file
  281: that is part of the Library, the object code for the work may be a
  282: derivative work of the Library even though the source code is not.
  283: Whether this is true is especially significant if the work can be
  284: linked without the Library, or if the work is itself a library.  The
  285: threshold for this to be true is not precisely defined by law.
  286: 
  287:   If such an object file uses only numerical parameters, data
  288: structure layouts and accessors, and small macros and small inline
  289: functions (ten lines or less in length), then the use of the object
  290: file is unrestricted, regardless of whether it is legally a derivative
  291: work.  (Executables containing this object code plus portions of the
  292: Library will still fall under Section 6.)
  293: 
  294:   Otherwise, if the work is a derivative of the Library, you may
  295: distribute the object code for the work under the terms of Section 6.
  296: Any executables containing that work also fall under Section 6,
  297: whether or not they are linked directly with the Library itself.
  298: 
  299: @item
  300: As an exception to the Sections above, you may also combine or
  301: link a ``work that uses the Library'' with the Library to produce a
  302: work containing portions of the Library, and distribute that work
  303: under terms of your choice, provided that the terms permit
  304: modification of the work for the customer's own use and reverse
  305: engineering for debugging such modifications.
  306: 
  307:   You must give prominent notice with each copy of the work that the
  308: Library is used in it and that the Library and its use are covered by
  309: this License.  You must supply a copy of this License.  If the work
  310: during execution displays copyright notices, you must include the
  311: copyright notice for the Library among them, as well as a reference
  312: directing the user to the copy of this License.  Also, you must do one
  313: of these things:
  314: 
  315: @enumerate a
  316: @item
  317: Accompany the work with the complete corresponding
  318: machine-readable source code for the Library including whatever
  319: changes were used in the work (which must be distributed under
  320: Sections 1 and 2 above); and, if the work is an executable linked
  321: with the Library, with the complete machine-readable ``work that
  322: uses the Library'', as object code and/or source code, so that the
  323: user can modify the Library and then relink to produce a modified
  324: executable containing the modified Library.  (It is understood
  325: that the user who changes the contents of definitions files in the
  326: Library will not necessarily be able to recompile the application
  327: to use the modified definitions.)
  328: 
  329: @item
  330: Use a suitable shared library mechanism for linking with the Library.  A
  331: suitable mechanism is one that (1) uses at run time a copy of the
  332: library already present on the user's computer system, rather than
  333: copying library functions into the executable, and (2) will operate
  334: properly with a modified version of the library, if the user installs
  335: one, as long as the modified version is interface-compatible with the
  336: version that the work was made with.
  337: 
  338: @item
  339: Accompany the work with a written offer, valid for at
  340: least three years, to give the same user the materials
  341: specified in Subsection 6a, above, for a charge no more
  342: than the cost of performing this distribution.
  343: 
  344: @item
  345: If distribution of the work is made by offering access to copy
  346: from a designated place, offer equivalent access to copy the above
  347: specified materials from the same place.

  353: 
  354:   For an executable, the required form of the ``work that uses the
  355: Library'' must include any data and utility programs needed for
  356: reproducing the executable from it.  However, as a special exception,
  357: the materials to be distributed need not include anything that is
  358: normally distributed (in either source or binary form) with the major
  359: components (compiler, kernel, and so on) of the operating system on

  362: 
  363:   It may happen that this requirement contradicts the license
  364: restrictions of other proprietary libraries that do not normally

  522: @appendixsubsec How to Apply These Terms to Your New Libraries
  523: 
  524:   If you develop a new library, and you want it to be of the greatest
  525: possible use to the public, we recommend making it free software that
  526: everyone can redistribute and change.  You can do so by permitting
  527: redistribution under these terms (or, alternatively, under the terms of the
  528: ordinary General Public License).
  529: 
  530:   To apply these terms, attach the following notices to the library.  It is
  531: safest to attach them to the start of each source file to most effectively
  532: convey the exclusion of warranty; and each file should have at least the
  533: ``copyright'' line and a pointer to where the full notice is found.
