   1            GNU LESSER GENERAL PUBLIC LICENSE
   2                 Version 2.1, February 1999
   3  
   4   Copyright (C) 1991, 1999 Free Software Foundation, Inc.
   5       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
   6   Everyone is permitted to copy and distribute verbatim copies
   7   of this license document, but changing it is not allowed.
   8  
   9  [This is the first released version of the Lesser GPL.  It also counts
  10   as the successor of the GNU Library Public License, version 2, hence
  11   the version number 2.1.]
  12  
  13                  Preamble
  14  
  15    The licenses for most software are designed to take away your
  16  freedom to share and change it.  By contrast, the GNU General Public
  17  Licenses are intended to guarantee your freedom to share and change
  18  free software--to make sure the software is free for all its users.
  19  
  20    This license, the Lesser General Public License, applies to some
  21  specially designated software packages--typically libraries--of the
  22  Free Software Foundation and other authors who decide to use it.  You
  23  can use it too, but we suggest you first think carefully about whether
  24  this license or the ordinary General Public License is the better
  25  strategy to use in any particular case, based on the explanations below.
  26  
  27    When we speak of free software, we are referring to freedom of use,
  28  not price.  Our General Public Licenses are designed to make sure that
  29  you have the freedom to distribute copies of free software (and charge
  30  for this service if you wish); that you receive source code or can get
  31  it if you want it; that you can change the software and use pieces of
  32  it in new free programs; and that you are informed that you can do
  33  these things.
  34  
  35    To protect your rights, we need to make restrictions that forbid
  36  distributors to deny you these rights or to ask you to surrender these
  37  rights.  These restrictions translate to certain responsibilities for
  38  you if you distribute copies of the library or if you modify it.
  39  
  40    For example, if you distribute copies of the library, whether gratis
  41  or for a fee, you must give the recipients all the rights that we gave
  42  you.  You must make sure that they, too, receive or can get the source
  43  code.  If you link other code with the library, you must provide
  44  complete object files to the recipients, so that they can relink them
  45  with the library after making changes to the library and recompiling
  46  it.  And you must show them these terms so they know their rights.
  47  
  48    We protect your rights with a two-step method: (1) we copyright the
  49  library, and (2) we offer you this license, which gives you legal
  50  permission to copy, distribute and/or modify the library.
  51  
  52    To protect each distributor, we want to make it very clear that
  53  there is no warranty for the free library.  Also, if the library is
  54  modified by someone else and passed on, the recipients should know
  55  that what they have is not the original version, so that the original
  56  author's reputation will not be affected by problems that might be
  57  introduced by others.
  58  
  59    Finally, software patents pose a constant threat to the existence of
  60  any free program.  We wish to make sure that a company cannot
  61  effectively restrict the users of a free program by obtaining a
  62  restrictive license from a patent holder.  Therefore, we insist that
  63  any patent license obtained for a version of the library must be
  64  consistent with the full freedom of use specified in this license.
  65  
  66    Most GNU software, including some libraries, is covered by the
  67  ordinary GNU General Public License.  This license, the GNU Lesser
  68  General Public License, applies to certain designated libraries, and
  69  is quite different from the ordinary General Public License.  We use
  70  this license for certain libraries in order to permit linking those
  71  libraries into non-free programs.
  72  
  73    When a program is linked with a library, whether statically or using
  74  a shared library, the combination of the two is legally speaking a
  75  combined work, a derivative of the original library.  The ordinary
  76  General Public License therefore permits such linking only if the
  77  entire combination fits its criteria of freedom.  The Lesser General
  78  Public License permits more lax criteria for linking other code with
  79  the library.
  80  
  81    We call this license the "Lesser" General Public License because it
  82  does Less to protect the user's freedom than the ordinary General
  83  Public License.  It also provides other free software developers Less
  84  of an advantage over competing non-free programs.  These disadvantages
  85  are the reason we use the ordinary General Public License for many
  86  libraries.  However, the Lesser license provides advantages in certain
  87  special circumstances.
  88  
  89    For example, on rare occasions, there may be a special need to
  90  encourage the widest possible use of a certain library, so that it becomes
  91  a de-facto standard.  To achieve this, non-free programs must be
  92  allowed to use the library.  A more frequent case is that a free
  93  library does the same job as widely used non-free libraries.  In this
  94  case, there is little to gain by limiting the free library to free
  95  software only, so we use the Lesser General Public License.
  96  
  97    In other cases, permission to use a particular library in non-free
  98  programs enables a greater number of people to use a large body of
  99  free software.  For example, permission to use the GNU C Library in
 100  non-free programs enables many more people to use the whole GNU
 101  operating system, as well as its variant, the GNU/Linux operating
 102  system.
 103  
 104    Although the Lesser General Public License is Less protective of the
 105  users' freedom, it does ensure that the user of a program that is
 106  linked with the Library has the freedom and the wherewithal to run
 107  that program using a modified version of the Library.
 108  
 109    The precise terms and conditions for copying, distribution and
 110  modification follow.  Pay close attention to the difference between a
 111  "work based on the library" and a "work that uses the library".  The
 112  former contains code derived from the library, whereas the latter must
 113  be combined with the library in order to run.
 114  
 115            GNU LESSER GENERAL PUBLIC LICENSE
 116     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 117  
 118    0. This License Agreement applies to any software library or other
 119  program which contains a notice placed by the copyright holder or
 120  other authorized party saying it may be distributed under the terms of
 121  this Lesser General Public License (also called "this License").
 122  Each licensee is addressed as "you".
 123  
 124    A "library" means a collection of software functions and/or data
 125  prepared so as to be conveniently linked with application programs
 126  (which use some of those functions and data) to form executables.
 127  
 128    The "Library", below, refers to any such software library or work
 129  which has been distributed under these terms.  A "work based on the
 130  Library" means either the Library or any derivative work under
 131  copyright law: that is to say, a work containing the Library or a
 132  portion of it, either verbatim or with modifications and/or translated
 133  straightforwardly into another language.  (Hereinafter, translation is
 134  included without limitation in the term "modification".)
 135  
 136    "Source code" for a work means the preferred form of the work for
 137  making modifications to it.  For a library, complete source code means
 138  all the source code for all modules it contains, plus any associated
 139  interface definition files, plus the scripts used to control compilation
 140  and installation of the library.
 141  
 142    Activities other than copying, distribution and modification are not
 143  covered by this License; they are outside its scope.  The act of
 144  running a program using the Library is not restricted, and output from
 145  such a program is covered only if its contents constitute a work based
 146  on the Library (independent of the use of the Library in a tool for
 147  writing it).  Whether that is true depends on what the Library does
 148  and what the program that uses the Library does.
 149  
 150    1. You may copy and distribute verbatim copies of the Library's
 151  complete source code as you receive it, in any medium, provided that
 152  you conspicuously and appropriately publish on each copy an
 153  appropriate copyright notice and disclaimer of warranty; keep intact
 154  all the notices that refer to this License and to the absence of any
 155  warranty; and distribute a copy of this License along with the
 156  Library.
 157  
 158    You may charge a fee for the physical act of transferring a copy,
 159  and you may at your option offer warranty protection in exchange for a
 160  fee.
 161  
 162    2. You may modify your copy or copies of the Library or any portion
 163  of it, thus forming a work based on the Library, and copy and
 164  distribute such modifications or work under the terms of Section 1
 165  above, provided that you also meet all of these conditions:
 166  
 167      a) The modified work must itself be a software library.
 168  
 169      b) You must cause the files modified to carry prominent notices
 170      stating that you changed the files and the date of any change.
 171  
 172      c) You must cause the whole of the work to be licensed at no
 173      charge to all third parties under the terms of this License.
 174  
 175      d) If a facility in the modified Library refers to a function or a
 176      table of data to be supplied by an application program that uses
 177      the facility, other than as an argument passed when the facility
 178      is invoked, then you must make a good faith effort to ensure that,
 179      in the event an application does not supply such function or
 180      table, the facility still operates, and performs whatever part of
 181      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 the
 185      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 Public
 212  License instead of this License to a given copy of the Library.  To do
 213  this, you must alter all the notices that refer to this License, so
 214  that they refer to the ordinary GNU General Public License, version 2,
 215  instead of to this License.  (If a newer version than version 2 of the
 216  ordinary GNU General Public License has appeared, then you can specify
 217  that version instead if you wish.)  Do not make any other change in
 218  these notices.
 219  
 220    Once this change is made in a given copy, it is irreversible for
 221  that 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
 225  the 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
 235  from a designated place, then offering equivalent access to copy the
 236  source code from the same place satisfies the requirement to
 237  distribute the source code, even though third parties are not
 238  compelled to copy the 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
 243  work, in isolation, is not a derivative work of the Library, and
 244  therefore 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.
 250  Section 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
 260  structure layouts and accessors, and small macros and small inline
 261  functions (ten lines or less in length), then the use of the object
 262  file is unrestricted, regardless of whether it is legally a derivative
 263  work.  (Executables containing this object code plus portions of the
 264  Library 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
 273  work containing portions of the Library, and distribute that work
 274  under terms of your choice, provided that the terms permit
 275  modification of the work for the customer's own use and reverse
 276  engineering for 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
 294      that 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  
 298      b) Use a suitable shared library mechanism for linking with the
 299      Library.  A suitable mechanism is one that (1) uses at run time a
 300      copy of the library already present on the user's computer system,
 301      rather than copying library functions into the executable, and (2)
 302      will operate properly with a modified version of the library, if
 303      the user installs one, as long as the modified version is
 304      interface-compatible with the version that the work was made with.
 305  
 306      c) Accompany the work with a written offer, valid for at
 307      least three years, to give the same user the materials
 308      specified in Subsection 6a, above, for a charge no more
 309      than the cost of performing this distribution.
 310  
 311      d) If distribution of the work is made by offering access to copy
 312      from a designated place, offer equivalent access to copy the above
 313      specified materials from the same place.
 314  
 315      e) Verify that the user has already received a copy of these
 316      materials or that you have already sent this user a copy.
 317  
 318    For an executable, the required form of the "work that uses the
 319  Library" must include any data and utility programs needed for
 320  reproducing the executable from it.  However, as a special exception,
 321  the materials to be distributed need not include anything that is
 322  normally distributed (in either source or binary form) with the major
 323  components (compiler, kernel, and so on) of the operating system on
 324  which the executable runs, unless that component itself accompanies
 325  the executable.
 326  
 327    It may happen that this requirement contradicts the license
 328  restrictions of other proprietary libraries that do not normally
 329  accompany the operating system.  Such a contradiction means you cannot
 330  use both them and the Library together in an executable that you
 331  distribute.
 332  
 333    7. You may place library facilities that are a work based on the
 334  Library side-by-side in a single library together with other library
 335  facilities not covered by this License, and distribute such a combined
 336  library, provided that the separate distribution of the work based on
 337  the Library and of the other library facilities is otherwise
 338  permitted, and provided that you do these two things:
 339  
 340      a) Accompany the combined library with a copy of the same work
 341      based on the Library, uncombined with any other library
 342      facilities.  This must be distributed under the terms of the
 343      Sections above.
 344  
 345      b) Give prominent notice with the combined library of the fact
 346      that part of it is a work based on the Library, and explaining
 347      where to find the accompanying uncombined form of the same work.
 348  
 349    8. You may not copy, modify, sublicense, link with, or distribute
 350  the Library except as expressly provided under this License.  Any
 351  attempt otherwise to copy, modify, sublicense, link with, or
 352  distribute the Library is void, and will automatically terminate your
 353  rights under this License.  However, parties who have received copies,
 354  or rights, from you under this License will not have their licenses
 355  terminated so long as such parties remain in full compliance.
 356  
 357    9. You are not required to accept this License, since you have not
 358  signed it.  However, nothing else grants you permission to modify or
 359  distribute the Library or its derivative works.  These actions are
 360  prohibited by law if you do not accept this License.  Therefore, by
 361  modifying or distributing the Library (or any work based on the
 362  Library), you indicate your acceptance of this License to do so, and
 363  all its terms and conditions for copying, distributing or modifying
 364  the Library or works based on it.
 365  
 366    10. Each time you redistribute the Library (or any work based on the
 367  Library), the recipient automatically receives a license from the
 368  original licensor to copy, distribute, link with or modify the Library
 369  subject to these terms and conditions.  You may not impose any further
 370  restrictions on the recipients' exercise of the rights granted herein.
 371  You are not responsible for enforcing compliance by third parties with
 372  this License.
 373  
 374    11. If, as a consequence of a court judgment or allegation of patent
 375  infringement or for any other reason (not limited to patent issues),
 376  conditions are imposed on you (whether by court order, agreement or
 377  otherwise) that contradict the conditions of this License, they do not
 378  excuse you from the conditions of this License.  If you cannot
 379  distribute so as to satisfy simultaneously your obligations under this
 380  License and any other pertinent obligations, then as a consequence you
 381  may not distribute the Library at all.  For example, if a patent
 382  license would not permit royalty-free redistribution of the Library by
 383  all those who receive copies directly or indirectly through you, then
 384  the only way you could satisfy both it and this License would be to
 385  refrain entirely from distribution of the Library.
 386  
 387  If any portion of this section is held invalid or unenforceable under any
 388  particular circumstance, the balance of the section is intended to apply,
 389  and the section as a whole is intended to apply in other circumstances.
 390  
 391  It is not the purpose of this section to induce you to infringe any
 392  patents or other property right claims or to contest validity of any
 393  such claims; this section has the sole purpose of protecting the
 394  integrity of the free software distribution system which is
 395  implemented by public license practices.  Many people have made
 396  generous contributions to the wide range of software distributed
 397  through that system in reliance on consistent application of that
 398  system; it is up to the author/donor to decide if he or she is willing
 399  to distribute software through any other system and a licensee cannot
 400  impose that choice.
 401  
 402  This section is intended to make thoroughly clear what is believed to
 403  be a consequence of the rest of this License.
 404  
 405    12. If the distribution and/or use of the Library is restricted in
 406  certain countries either by patents or by copyrighted interfaces, the
 407  original copyright holder who places the Library under this License may add
 408  an explicit geographical distribution limitation excluding those countries,
 409  so that distribution is permitted only in or among countries not thus
 410  excluded.  In such case, this License incorporates the limitation as if
 411  written in the body of this License.
 412  
 413    13. The Free Software Foundation may publish revised and/or new
 414  versions of the Lesser General Public License from time to time.
 415  Such new versions will be similar in spirit to the present version,
 416  but may differ in detail to address new problems or concerns.
 417  
 418  Each version is given a distinguishing version number.  If the Library
 419  specifies a version number of this License which applies to it and
 420  "any later version", you have the option of following the terms and
 421  conditions either of that version or of any later version published by
 422  the Free Software Foundation.  If the Library does not specify a
 423  license version number, you may choose any version ever published by
 424  the Free Software Foundation.
 425  
 426    14. If you wish to incorporate parts of the Library into other free
 427  programs whose distribution conditions are incompatible with these,
 428  write to the author to ask for permission.  For software which is
 429  copyrighted by the Free Software Foundation, write to the Free
 430  Software Foundation; we sometimes make exceptions for this.  Our
 431  decision will be guided by the two goals of preserving the free status
 432  of all derivatives of our free software and of promoting the sharing
 433  and reuse of software generally.
 434  
 435                  NO WARRANTY
 436  
 437    15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
 438  WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
 439  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
 440  OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
 441  KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
