      2  1.1  christos                        Version 3, 29 June 2007
      3  1.1  christos 
      4  1.1  christos  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
      5  1.1  christos  Everyone is permitted to copy and distribute verbatim copies
      6  1.1  christos  of this license document, but changing it is not allowed.
      7  1.1  christos 
      8  1.1  christos                             Preamble
      9  1.1  christos 
     10  1.1  christos   The GNU General Public License is a free, copyleft license for
     11  1.1  christos software and other kinds of works.
     12  1.1  christos 
     13  1.1  christos   The licenses for most software and other practical works are designed
     14  1.1  christos to take away your freedom to share and change the works.  By contrast,
     15  1.1  christos the GNU General Public License is intended to guarantee your freedom to
     16  1.1  christos share and change all versions of a program--to make sure it remains free
     17  1.1  christos software for all its users.  We, the Free Software Foundation, use the
     18  1.1  christos GNU General Public License for most of our software; it applies also to
     19  1.1  christos any other work released this way by its authors.  You can apply it to
     20  1.1  christos your programs, too.
     21  1.1  christos 
     22  1.1  christos   When we speak of free software, we are referring to freedom, not
     23  1.1  christos price.  Our General Public Licenses are designed to make sure that you
     24  1.1  christos have the freedom to distribute copies of free software (and charge for
     25  1.1  christos them if you wish), that you receive source code or can get it if you
     26  1.1  christos want it, that you can change the software or use pieces of it in new
     27  1.1  christos free programs, and that you know you can do these things.
     28  1.1  christos 
     29  1.1  christos   To protect your rights, we need to prevent others from denying you
     30  1.1  christos these rights or asking you to surrender the rights.  Therefore, you have
     31  1.1  christos certain responsibilities if you distribute copies of the software, or if
     32  1.1  christos you modify it: responsibilities to respect the freedom of others.
     33  1.1  christos 
     34  1.1  christos   For example, if you distribute copies of such a program, whether
     35  1.1  christos gratis or for a fee, you must pass on to the recipients the same
     36  1.1  christos freedoms that you received.  You must make sure that they, too, receive
     37  1.1  christos or can get the source code.  And you must show them these terms so they
     38  1.1  christos know their rights.
     39  1.1  christos 
     40  1.1  christos   Developers that use the GNU GPL protect your rights with two steps:
     41  1.1  christos (1) assert copyright on the software, and (2) offer you this License
     42  1.1  christos giving you legal permission to copy, distribute and/or modify it.
     43  1.1  christos 
     44  1.1  christos   For the developers' and authors' protection, the GPL clearly explains
     45  1.1  christos that there is no warranty for this free software.  For both users' and
     46  1.1  christos authors' sake, the GPL requires that modified versions be marked as
     47  1.1  christos changed, so that their problems will not be attributed erroneously to
     48  1.1  christos authors of previous versions.
     49  1.1  christos 
     50  1.1  christos   Some devices are designed to deny users access to install or run
     51  1.1  christos modified versions of the software inside them, although the manufacturer
     52  1.1  christos can do so.  This is fundamentally incompatible with the aim of
     53  1.1  christos protecting users' freedom to change the software.  The systematic
     54  1.1  christos pattern of such abuse occurs in the area of products for individuals to
     55  1.1  christos use, which is precisely where it is most unacceptable.  Therefore, we
     56  1.1  christos have designed this version of the GPL to prohibit the practice for those
     57  1.1  christos products.  If such problems arise substantially in other domains, we
     58  1.1  christos stand ready to extend this provision to those domains in future versions
     59  1.1  christos of the GPL, as needed to protect the freedom of users.
     60  1.1  christos 
     61  1.1  christos   Finally, every program is threatened constantly by software patents.
     62  1.1  christos States should not allow patents to restrict development and use of
     63  1.1  christos software on general-purpose computers, but in those that do, we wish to
     64  1.1  christos avoid the special danger that patents applied to a free program could
     65  1.1  christos make it effectively proprietary.  To prevent this, the GPL assures that
     66  1.1  christos patents cannot be used to render the program non-free.
     67  1.1  christos 
     68  1.1  christos   The precise terms and conditions for copying, distribution and
     69  1.1  christos modification follow.
     70  1.1  christos 
     71  1.1  christos                        TERMS AND CONDITIONS
     72  1.1  christos 
     73  1.1  christos   0. Definitions.
     74  1.1  christos 
     75  1.1  christos   "This License" refers to version 3 of the GNU General Public License.
     76  1.1  christos 
     77  1.1  christos   "Copyright" also means copyright-like laws that apply to other kinds of
     78  1.1  christos works, such as semiconductor masks.
     79  1.1  christos 
     80  1.1  christos   "The Program" refers to any copyrightable work licensed under this
     81  1.1  christos License.  Each licensee is addressed as "you".  "Licensees" and
     82  1.1  christos "recipients" may be individuals or organizations.
     83  1.1  christos 
     84  1.1  christos   To "modify" a work means to copy from or adapt all or part of the work
     85  1.1  christos in a fashion requiring copyright permission, other than the making of an
     86  1.1  christos exact copy.  The resulting work is called a "modified version" of the
     87  1.1  christos earlier work or a work "based on" the earlier work.
     88  1.1  christos 
     89  1.1  christos   A "covered work" means either the unmodified Program or a work based
     90  1.1  christos on the Program.
     91  1.1  christos 
     92  1.1  christos   To "propagate" a work means to do anything with it that, without
     93  1.1  christos permission, would make you directly or secondarily liable for
     94  1.1  christos infringement under applicable copyright law, except executing it on a
     95  1.1  christos computer or modifying a private copy.  Propagation includes copying,
     96  1.1  christos distribution (with or without modification), making available to the
     97  1.1  christos public, and in some countries other activities as well.
     98  1.1  christos 
     99  1.1  christos   To "convey" a work means any kind of propagation that enables other
    100  1.1  christos parties to make or receive copies.  Mere interaction with a user through
    101  1.1  christos a computer network, with no transfer of a copy, is not conveying.
    102  1.1  christos 
    103  1.1  christos   An interactive user interface displays "Appropriate Legal Notices"
    104  1.1  christos to the extent that it includes a convenient and prominently visible
    105  1.1  christos feature that (1) displays an appropriate copyright notice, and (2)
    106  1.1  christos tells the user that there is no warranty for the work (except to the
    107  1.1  christos extent that warranties are provided), that licensees may convey the
    108  1.1  christos work under this License, and how to view a copy of this License.  If
    109  1.1  christos the interface presents a list of user commands or options, such as a
    110  1.1  christos menu, a prominent item in the list meets this criterion.
    111  1.1  christos 
    112  1.1  christos   1. Source Code.
    113  1.1  christos 
    114  1.1  christos   The "source code" for a work means the preferred form of the work
    115  1.1  christos for making modifications to it.  "Object code" means any non-source
    116  1.1  christos form of a work.
    117  1.1  christos 
    118  1.1  christos   A "Standard Interface" means an interface that either is an official
    119  1.1  christos standard defined by a recognized standards body, or, in the case of
    120  1.1  christos interfaces specified for a particular programming language, one that
    121  1.1  christos is widely used among developers working in that language.
    122  1.1  christos 
    123  1.1  christos   The "System Libraries" of an executable work include anything, other
    124  1.1  christos than the work as a whole, that (a) is included in the normal form of
    125  1.1  christos packaging a Major Component, but which is not part of that Major
    126  1.1  christos Component, and (b) serves only to enable use of the work with that
    127  1.1  christos Major Component, or to implement a Standard Interface for which an
    128  1.1  christos implementation is available to the public in source code form.  A
    129  1.1  christos "Major Component", in this context, means a major essential component
    130  1.1  christos (kernel, window system, and so on) of the specific operating system
    131  1.1  christos (if any) on which the executable work runs, or a compiler used to
    132  1.1  christos produce the work, or an object code interpreter used to run it.
    133  1.1  christos 
    134  1.1  christos   The "Corresponding Source" for a work in object code form means all
    135  1.1  christos the source code needed to generate, install, and (for an executable
    136  1.1  christos work) run the object code and to modify the work, including scripts to
    137  1.1  christos control those activities.  However, it does not include the work's
    138  1.1  christos System Libraries, or general-purpose tools or generally available free
    139  1.1  christos programs which are used unmodified in performing those activities but
    140  1.1  christos which are not part of the work.  For example, Corresponding Source
    141  1.1  christos includes interface definition files associated with source files for
    142  1.1  christos the work, and the source code for shared libraries and dynamically
    143  1.1  christos linked subprograms that the work is specifically designed to require,
    144  1.1  christos such as by intimate data communication or control flow between those
    145  1.1  christos subprograms and other parts of the work.
    146  1.1  christos 
    147  1.1  christos   The Corresponding Source need not include anything that users
    148  1.1  christos can regenerate automatically from other parts of the Corresponding
    149  1.1  christos Source.
    150  1.1  christos 
    151  1.1  christos   The Corresponding Source for a work in source code form is that
    152  1.1  christos same work.
    153  1.1  christos 
    154  1.1  christos   2. Basic Permissions.
    155  1.1  christos 
    156  1.1  christos   All rights granted under this License are granted for the term of
    157  1.1  christos copyright on the Program, and are irrevocable provided the stated
    158  1.1  christos conditions are met.  This License explicitly affirms your unlimited
    159  1.1  christos permission to run the unmodified Program.  The output from running a
    160  1.1  christos covered work is covered by this License only if the output, given its
    161  1.1  christos content, constitutes a covered work.  This License acknowledges your
    162  1.1  christos rights of fair use or other equivalent, as provided by copyright law.
    163  1.1  christos 
    164  1.1  christos   You may make, run and propagate covered works that you do not
    165  1.1  christos convey, without conditions so long as your license otherwise remains
    166  1.1  christos in force.  You may convey covered works to others for the sole purpose
    167  1.1  christos of having them make modifications exclusively for you, or provide you
    168  1.1  christos with facilities for running those works, provided that you comply with
    169  1.1  christos the terms of this License in conveying all material for which you do
    170  1.1  christos not control copyright.  Those thus making or running the covered works
    171  1.1  christos for you must do so exclusively on your behalf, under your direction
    172  1.1  christos and control, on terms that prohibit them from making any copies of
    173  1.1  christos your copyrighted material outside their relationship with you.
    174  1.1  christos 
    175  1.1  christos   Conveying under any other circumstances is permitted solely under
    176  1.1  christos the conditions stated below.  Sublicensing is not allowed; section 10
    177  1.1  christos makes it unnecessary.
    178  1.1  christos 
    179  1.1  christos   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    180  1.1  christos 
    181  1.1  christos   No covered work shall be deemed part of an effective technological
    182  1.1  christos measure under any applicable law fulfilling obligations under article
    183  1.1  christos 11 of the WIPO copyright treaty adopted on 20 December 1996, or
    184  1.1  christos similar laws prohibiting or restricting circumvention of such
    185  1.1  christos measures.
    186  1.1  christos 
    187  1.1  christos   When you convey a covered work, you waive any legal power to forbid
    188  1.1  christos circumvention of technological measures to the extent such circumvention
    189  1.1  christos is effected by exercising rights under this License with respect to
    190  1.1  christos the covered work, and you disclaim any intention to limit operation or
    191  1.1  christos modification of the work as a means of enforcing, against the work's
    192  1.1  christos users, your or third parties' legal rights to forbid circumvention of
    193  1.1  christos technological measures.
    194  1.1  christos 
    195  1.1  christos   4. Conveying Verbatim Copies.
    196  1.1  christos 
    197  1.1  christos   You may convey verbatim copies of the Program's source code as you
    198  1.1  christos receive it, in any medium, provided that you conspicuously and
    199  1.1  christos appropriately publish on each copy an appropriate copyright notice;
    200  1.1  christos keep intact all notices stating that this License and any
    201  1.1  christos non-permissive terms added in accord with section 7 apply to the code;
    202  1.1  christos keep intact all notices of the absence of any warranty; and give all
    203  1.1  christos recipients a copy of this License along with the Program.
    204  1.1  christos 
    205  1.1  christos   You may charge any price or no price for each copy that you convey,
    206  1.1  christos and you may offer support or warranty protection for a fee.
    207  1.1  christos 
    208  1.1  christos   5. Conveying Modified Source Versions.
    209  1.1  christos 
    210  1.1  christos   You may convey a work based on the Program, or the modifications to
    211  1.1  christos produce it from the Program, in the form of source code under the
    212  1.1  christos terms of section 4, provided that you also meet all of these conditions:
    213  1.1  christos 
    214  1.1  christos     a) The work must carry prominent notices stating that you modified
    215  1.1  christos     it, and giving a relevant date.
    216  1.1  christos 
    217  1.1  christos     b) The work must carry prominent notices stating that it is
    218  1.1  christos     released under this License and any conditions added under section
    219  1.1  christos     7.  This requirement modifies the requirement in section 4 to
    220  1.1  christos     "keep intact all notices".
    221  1.1  christos 
    222  1.1  christos     c) You must license the entire work, as a whole, under this
    223  1.1  christos     License to anyone who comes into possession of a copy.  This
    224  1.1  christos     License will therefore apply, along with any applicable section 7
    225  1.1  christos     additional terms, to the whole of the work, and all its parts,
    226  1.1  christos     regardless of how they are packaged.  This License gives no
    227  1.1  christos     permission to license the work in any other way, but it does not
    228  1.1  christos     invalidate such permission if you have separately received it.
    229  1.1  christos 
    230  1.1  christos     d) If the work has interactive user interfaces, each must display
    231  1.1  christos     Appropriate Legal Notices; however, if the Program has interactive
    232  1.1  christos     interfaces that do not display Appropriate Legal Notices, your
    233  1.1  christos     work need not make them do so.
    234  1.1  christos 
    235  1.1  christos   A compilation of a covered work with other separate and independent
    236  1.1  christos works, which are not by their nature extensions of the covered work,
    237  1.1  christos and which are not combined with it such as to form a larger program,
    238  1.1  christos in or on a volume of a storage or distribution medium, is called an
    239  1.1  christos "aggregate" if the compilation and its resulting copyright are not
    240  1.1  christos used to limit the access or legal rights of the compilation's users
    241  1.1  christos beyond what the individual works permit.  Inclusion of a covered work
    242  1.1  christos in an aggregate does not cause this License to apply to the other
    243  1.1  christos parts of the aggregate.
    244  1.1  christos 
    245  1.1  christos   6. Conveying Non-Source Forms.
    246  1.1  christos 
    247  1.1  christos   You may convey a covered work in object code form under the terms
    248  1.1  christos of sections 4 and 5, provided that you also convey the
    249  1.1  christos machine-readable Corresponding Source under the terms of this License,
    250  1.1  christos in one of these ways:
    251  1.1  christos 
    252  1.1  christos     a) Convey the object code in, or embodied in, a physical product
    253  1.1  christos     (including a physical distribution medium), accompanied by the
    254  1.1  christos     Corresponding Source fixed on a durable physical medium
    255  1.1  christos     customarily used for software interchange.
    256  1.1  christos 
    257  1.1  christos     b) Convey the object code in, or embodied in, a physical product
    258  1.1  christos     (including a physical distribution medium), accompanied by a
    259  1.1  christos     written offer, valid for at least three years and valid for as
    260  1.1  christos     long as you offer spare parts or customer support for that product
    261  1.1  christos     model, to give anyone who possesses the object code either (1) a
    262  1.1  christos     copy of the Corresponding Source for all the software in the
    263  1.1  christos     product that is covered by this License, on a durable physical
    264  1.1  christos     medium customarily used for software interchange, for a price no
    265  1.1  christos     more than your reasonable cost of physically performing this
    266  1.1  christos     conveying of source, or (2) access to copy the
    267  1.1  christos     Corresponding Source from a network server at no charge.
    268  1.1  christos 
    269  1.1  christos     c) Convey individual copies of the object code with a copy of the
    270  1.1  christos     written offer to provide the Corresponding Source.  This
    271  1.1  christos     alternative is allowed only occasionally and noncommercially, and
    272  1.1  christos     only if you received the object code with such an offer, in accord
    273  1.1  christos     with subsection 6b.
    274  1.1  christos 
    275  1.1  christos     d) Convey the object code by offering access from a designated
    276  1.1  christos     place (gratis or for a charge), and offer equivalent access to the
    277  1.1  christos     Corresponding Source in the same way through the same place at no
    278  1.1  christos     further charge.  You need not require recipients to copy the
    279  1.1  christos     Corresponding Source along with the object code.  If the place to
    280  1.1  christos     copy the object code is a network server, the Corresponding Source
    281  1.1  christos     may be on a different server (operated by you or a third party)
    282  1.1  christos     that supports equivalent copying facilities, provided you maintain
    283  1.1  christos     clear directions next to the object code saying where to find the
    284  1.1  christos     Corresponding Source.  Regardless of what server hosts the
    285  1.1  christos     Corresponding Source, you remain obligated to ensure that it is
    286  1.1  christos     available for as long as needed to satisfy these requirements.
    287  1.1  christos 
    288  1.1  christos     e) Convey the object code using peer-to-peer transmission, provided
    289  1.1  christos     you inform other peers where the object code and Corresponding
    290  1.1  christos     Source of the work are being offered to the general public at no
    291  1.1  christos     charge under subsection 6d.
    292  1.1  christos 
    293  1.1  christos   A separable portion of the object code, whose source code is excluded
    294  1.1  christos from the Corresponding Source as a System Library, need not be
    295  1.1  christos included in conveying the object code work.
    296  1.1  christos 
    297  1.1  christos   A "User Product" is either (1) a "consumer product", which means any
    298  1.1  christos tangible personal property which is normally used for personal, family,
    299  1.1  christos or household purposes, or (2) anything designed or sold for incorporation
    300  1.1  christos into a dwelling.  In determining whether a product is a consumer product,
    301  1.1  christos doubtful cases shall be resolved in favor of coverage.  For a particular
    302  1.1  christos product received by a particular user, "normally used" refers to a
    303  1.1  christos typical or common use of that class of product, regardless of the status
    304  1.1  christos of the particular user or of the way in which the particular user
    305  1.1  christos actually uses, or expects or is expected to use, the product.  A product
    306  1.1  christos is a consumer product regardless of whether the product has substantial
    307  1.1  christos commercial, industrial or non-consumer uses, unless such uses represent
    308  1.1  christos the only significant mode of use of the product.
    309  1.1  christos 
    310  1.1  christos   "Installation Information" for a User Product means any methods,
    311  1.1  christos procedures, authorization keys, or other information required to install
    312  1.1  christos and execute modified versions of a covered work in that User Product from
    313  1.1  christos a modified version of its Corresponding Source.  The information must
    314  1.1  christos suffice to ensure that the continued functioning of the modified object
    315  1.1  christos code is in no case prevented or interfered with solely because
    316  1.1  christos modification has been made.
    317  1.1  christos 
    318  1.1  christos   If you convey an object code work under this section in, or with, or
    319  1.1  christos specifically for use in, a User Product, and the conveying occurs as
    320  1.1  christos part of a transaction in which the right of possession and use of the
    321  1.1  christos User Product is transferred to the recipient in perpetuity or for a
    322  1.1  christos fixed term (regardless of how the transaction is characterized), the
    323  1.1  christos Corresponding Source conveyed under this section must be accompanied
    324  1.1  christos by the Installation Information.  But this requirement does not apply
    325  1.1  christos if neither you nor any third party retains the ability to install
    326  1.1  christos modified object code on the User Product (for example, the work has
    327  1.1  christos been installed in ROM).
    328  1.1  christos 
    329  1.1  christos   The requirement to provide Installation Information does not include a
    330  1.1  christos requirement to continue to provide support service, warranty, or updates
    331  1.1  christos for a work that has been modified or installed by the recipient, or for
    332  1.1  christos the User Product in which it has been modified or installed.  Access to a
    333  1.1  christos network may be denied when the modification itself materially and
    334  1.1  christos adversely affects the operation of the network or violates the rules and
    335  1.1  christos protocols for communication across the network.
    336  1.1  christos 
    337  1.1  christos   Corresponding Source conveyed, and Installation Information provided,
    338  1.1  christos in accord with this section must be in a format that is publicly
    339  1.1  christos documented (and with an implementation available to the public in
    340  1.1  christos source code form), and must require no special password or key for
    341  1.1  christos unpacking, reading or copying.
    342  1.1  christos 
    343  1.1  christos   7. Additional Terms.
    344  1.1  christos 
    345  1.1  christos   "Additional permissions" are terms that supplement the terms of this
    346  1.1  christos License by making exceptions from one or more of its conditions.
    347  1.1  christos Additional permissions that are applicable to the entire Program shall
    348  1.1  christos be treated as though they were included in this License, to the extent
    349  1.1  christos that they are valid under applicable law.  If additional permissions
    350  1.1  christos apply only to part of the Program, that part may be used separately
    351  1.1  christos under those permissions, but the entire Program remains governed by
    352  1.1  christos this License without regard to the additional permissions.
    353  1.1  christos 
    354  1.1  christos   When you convey a copy of a covered work, you may at your option
    355  1.1  christos remove any additional permissions from that copy, or from any part of
    356  1.1  christos it.  (Additional permissions may be written to require their own
    357  1.1  christos removal in certain cases when you modify the work.)  You may place
    358  1.1  christos additional permissions on material, added by you to a covered work,
    359  1.1  christos for which you have or can give appropriate copyright permission.
    360  1.1  christos 
    361  1.1  christos   Notwithstanding any other provision of this License, for material you
    362  1.1  christos add to a covered work, you may (if authorized by the copyright holders of
    363  1.1  christos that material) supplement the terms of this License with terms:
    364  1.1  christos 
    365  1.1  christos     a) Disclaiming warranty or limiting liability differently from the
    366  1.1  christos     terms of sections 15 and 16 of this License; or
    367  1.1  christos 
    368  1.1  christos     b) Requiring preservation of specified reasonable legal notices or
    369  1.1  christos     author attributions in that material or in the Appropriate Legal
    370  1.1  christos     Notices displayed by works containing it; or
    371  1.1  christos 
    372  1.1  christos     c) Prohibiting misrepresentation of the origin of that material, or
    373  1.1  christos     requiring that modified versions of such material be marked in
    374  1.1  christos     reasonable ways as different from the original version; or
    375  1.1  christos 
    376  1.1  christos     d) Limiting the use for publicity purposes of names of licensors or
    377  1.1  christos     authors of the material; or
    378  1.1  christos 
    379  1.1  christos     e) Declining to grant rights under trademark law for use of some
    380  1.1  christos     trade names, trademarks, or service marks; or
    381  1.1  christos 
    382  1.1  christos     f) Requiring indemnification of licensors and authors of that
    383  1.1  christos     material by anyone who conveys the material (or modified versions of
    384  1.1  christos     it) with contractual assumptions of liability to the recipient, for
    385  1.1  christos     any liability that these contractual assumptions directly impose on
    386  1.1  christos     those licensors and authors.
    387  1.1  christos 
    388  1.1  christos   All other non-permissive additional terms are considered "further
    389  1.1  christos restrictions" within the meaning of section 10.  If the Program as you
    390  1.1  christos received it, or any part of it, contains a notice stating that it is
    391  1.1  christos governed by this License along with a term that is a further
    392  1.1  christos restriction, you may remove that term.  If a license document contains
    393  1.1  christos a further restriction but permits relicensing or conveying under this
    394  1.1  christos License, you may add to a covered work material governed by the terms
    395  1.1  christos of that license document, provided that the further restriction does
    396  1.1  christos not survive such relicensing or conveying.
    397  1.1  christos 
    398  1.1  christos   If you add terms to a covered work in accord with this section, you
    399  1.1  christos must place, in the relevant source files, a statement of the
    400  1.1  christos additional terms that apply to those files, or a notice indicating
    401  1.1  christos where to find the applicable terms.
    402  1.1  christos 
    403  1.1  christos   Additional terms, permissive or non-permissive, may be stated in the
    404  1.1  christos form of a separately written license, or stated as exceptions;
    405  1.1  christos the above requirements apply either way.
    406  1.1  christos 
    407  1.1  christos   8. Termination.
    408  1.1  christos 
    409  1.1  christos   You may not propagate or modify a covered work except as expressly
    410  1.1  christos provided under this License.  Any attempt otherwise to propagate or
    411  1.1  christos modify it is void, and will automatically terminate your rights under
    412  1.1  christos this License (including any patent licenses granted under the third
    413  1.1  christos paragraph of section 11).
    414  1.1  christos 
    415  1.1  christos   However, if you cease all violation of this License, then your
    416  1.1  christos license from a particular copyright holder is reinstated (a)
    417  1.1  christos provisionally, unless and until the copyright holder explicitly and
    418  1.1  christos finally terminates your license, and (b) permanently, if the copyright
    419  1.1  christos holder fails to notify you of the violation by some reasonable means
    420  1.1  christos prior to 60 days after the cessation.
    421  1.1  christos 
    422  1.1  christos   Moreover, your license from a particular copyright holder is
    423  1.1  christos reinstated permanently if the copyright holder notifies you of the
    424  1.1  christos violation by some reasonable means, this is the first time you have
    425  1.1  christos received notice of violation of this License (for any work) from that
    426  1.1  christos copyright holder, and you cure the violation prior to 30 days after
    427  1.1  christos your receipt of the notice.
    428  1.1  christos 
    429  1.1  christos   Termination of your rights under this section does not terminate the
    430  1.1  christos licenses of parties who have received copies or rights from you under
    431  1.1  christos this License.  If your rights have been terminated and not permanently
    432  1.1  christos reinstated, you do not qualify to receive new licenses for the same
    433  1.1  christos material under section 10.
    434  1.1  christos 
    435  1.1  christos   9. Acceptance Not Required for Having Copies.
    436  1.1  christos 
    437  1.1  christos   You are not required to accept this License in order to receive or
    438  1.1  christos run a copy of the Program.  Ancillary propagation of a covered work
    439  1.1  christos occurring solely as a consequence of using peer-to-peer transmission
    440  1.1  christos to receive a copy likewise does not require acceptance.  However,
    441  1.1  christos nothing other than this License grants you permission to propagate or
    442  1.1  christos modify any covered work.  These actions infringe copyright if you do
    443  1.1  christos not accept this License.  Therefore, by modifying or propagating a
    444  1.1  christos covered work, you indicate your acceptance of this License to do so.
    445  1.1  christos 
    446  1.1  christos   10. Automatic Licensing of Downstream Recipients.
    447  1.1  christos 
    448  1.1  christos   Each time you convey a covered work, the recipient automatically
    449  1.1  christos receives a license from the original licensors, to run, modify and
    450  1.1  christos propagate that work, subject to this License.  You are not responsible
    451  1.1  christos for enforcing compliance by third parties with this License.
    452  1.1  christos 
    453  1.1  christos   An "entity transaction" is a transaction transferring control of an
    454  1.1  christos organization, or substantially all assets of one, or subdividing an
    455  1.1  christos organization, or merging organizations.  If propagation of a covered
    456  1.1  christos work results from an entity transaction, each party to that
    457  1.1  christos transaction who receives a copy of the work also receives whatever
    458  1.1  christos licenses to the work the party's predecessor in interest had or could
    459  1.1  christos give under the previous paragraph, plus a right to possession of the
    460  1.1  christos Corresponding Source of the work from the predecessor in interest, if
    461  1.1  christos the predecessor has it or can get it with reasonable efforts.
    462  1.1  christos 
    463  1.1  christos   You may not impose any further restrictions on the exercise of the
    464  1.1  christos rights granted or affirmed under this License.  For example, you may
    465  1.1  christos not impose a license fee, royalty, or other charge for exercise of
    466  1.1  christos rights granted under this License, and you may not initiate litigation
    467  1.1  christos (including a cross-claim or counterclaim in a lawsuit) alleging that
    468  1.1  christos any patent claim is infringed by making, using, selling, offering for
    469  1.1  christos sale, or importing the Program or any portion of it.
    470  1.1  christos 
    471  1.1  christos   11. Patents.
    472  1.1  christos 
    473  1.1  christos   A "contributor" is a copyright holder who authorizes use under this
    474  1.1  christos License of the Program or a work on which the Program is based.  The
    475  1.1  christos work thus licensed is called the contributor's "contributor version".
    476  1.1  christos 
    477  1.1  christos   A contributor's "essential patent claims" are all patent claims
    478  1.1  christos owned or controlled by the contributor, whether already acquired or
    479  1.1  christos hereafter acquired, that would be infringed by some manner, permitted
    480  1.1  christos by this License, of making, using, or selling its contributor version,
    481  1.1  christos but do not include claims that would be infringed only as a
    482  1.1  christos consequence of further modification of the contributor version.  For
    483  1.1  christos purposes of this definition, "control" includes the right to grant
    484  1.1  christos patent sublicenses in a manner consistent with the requirements of
    485  1.1  christos this License.
    486  1.1  christos 
    487  1.1  christos   Each contributor grants you a non-exclusive, worldwide, royalty-free
    488  1.1  christos patent license under the contributor's essential patent claims, to
    489  1.1  christos make, use, sell, offer for sale, import and otherwise run, modify and
    490  1.1  christos propagate the contents of its contributor version.
    491  1.1  christos 
    492  1.1  christos   In the following three paragraphs, a "patent license" is any express
    493  1.1  christos agreement or commitment, however denominated, not to enforce a patent
    494  1.1  christos (such as an express permission to practice a patent or covenant not to
    495  1.1  christos sue for patent infringement).  To "grant" such a patent license to a
    496  1.1  christos party means to make such an agreement or commitment not to enforce a
    497  1.1  christos patent against the party.
    498  1.1  christos 
    499  1.1  christos   If you convey a covered work, knowingly relying on a patent license,
    500  1.1  christos and the Corresponding Source of the work is not available for anyone
    501  1.1  christos to copy, free of charge and under the terms of this License, through a
    502  1.1  christos publicly available network server or other readily accessible means,
    503  1.1  christos then you must either (1) cause the Corresponding Source to be so
    504  1.1  christos available, or (2) arrange to deprive yourself of the benefit of the
    505  1.1  christos patent license for this particular work, or (3) arrange, in a manner
    506  1.1  christos consistent with the requirements of this License, to extend the patent
    507  1.1  christos license to downstream recipients.  "Knowingly relying" means you have
    508  1.1  christos actual knowledge that, but for the patent license, your conveying the
    509  1.1  christos covered work in a country, or your recipient's use of the covered work
    510  1.1  christos in a country, would infringe one or more identifiable patents in that
    511  1.1  christos country that you have reason to believe are valid.
    512  1.1  christos 
    513  1.1  christos   If, pursuant to or in connection with a single transaction or
    514  1.1  christos arrangement, you convey, or propagate by procuring conveyance of, a
    515  1.1  christos covered work, and grant a patent license to some of the parties
    516  1.1  christos receiving the covered work authorizing them to use, propagate, modify
    517  1.1  christos or convey a specific copy of the covered work, then the patent license
    518  1.1  christos you grant is automatically extended to all recipients of the covered
    519  1.1  christos work and works based on it.
    520  1.1  christos 
    521  1.1  christos   A patent license is "discriminatory" if it does not include within
    522  1.1  christos the scope of its coverage, prohibits the exercise of, or is
    523  1.1  christos conditioned on the non-exercise of one or more of the rights that are
    524  1.1  christos specifically granted under this License.  You may not convey a covered
    525  1.1  christos work if you are a party to an arrangement with a third party that is
    526  1.1  christos in the business of distributing software, under which you make payment
    527  1.1  christos to the third party based on the extent of your activity of conveying
    528  1.1  christos the work, and under which the third party grants, to any of the
    529  1.1  christos parties who would receive the covered work from you, a discriminatory
    530  1.1  christos patent license (a) in connection with copies of the covered work
    531  1.1  christos conveyed by you (or copies made from those copies), or (b) primarily
    532  1.1  christos for and in connection with specific products or compilations that
    533  1.1  christos contain the covered work, unless you entered into that arrangement,
    534  1.1  christos or that patent license was granted, prior to 28 March 2007.
    535  1.1  christos 
    536  1.1  christos   Nothing in this License shall be construed as excluding or limiting
    537  1.1  christos any implied license or other defenses to infringement that may
    538  1.1  christos otherwise be available to you under applicable patent law.
    539  1.1  christos 
    540  1.1  christos   12. No Surrender of Others' Freedom.
    541  1.1  christos 
    542  1.1  christos   If conditions are imposed on you (whether by court order, agreement or
    543  1.1  christos otherwise) that contradict the conditions of this License, they do not
    544  1.1  christos excuse you from the conditions of this License.  If you cannot convey a
    545  1.1  christos covered work so as to satisfy simultaneously your obligations under this
    546  1.1  christos License and any other pertinent obligations, then as a consequence you may
    547  1.1  christos not convey it at all.  For example, if you agree to terms that obligate you
    548  1.1  christos to collect a royalty for further conveying from those to whom you convey
    549  1.1  christos the Program, the only way you could satisfy both those terms and this
    550  1.1  christos License would be to refrain entirely from conveying the Program.
    551  1.1  christos 
    552  1.1  christos   13. Use with the GNU Affero General Public License.
    553  1.1  christos 
    554  1.1  christos   Notwithstanding any other provision of this License, you have
    555  1.1  christos permission to link or combine any covered work with a work licensed
    556  1.1  christos under version 3 of the GNU Affero General Public License into a single
    557  1.1  christos combined work, and to convey the resulting work.  The terms of this
    558  1.1  christos License will continue to apply to the part which is the covered work,
    559  1.1  christos but the special requirements of the GNU Affero General Public License,
    560  1.1  christos section 13, concerning interaction through a network will apply to the
    561  1.1  christos combination as such.
    562  1.1  christos 
    563  1.1  christos   14. Revised Versions of this License.
    564  1.1  christos 
    565  1.1  christos   The Free Software Foundation may publish revised and/or new versions of
    566  1.1  christos the GNU General Public License from time to time.  Such new versions will
    567  1.1  christos be similar in spirit to the present version, but may differ in detail to
    568  1.1  christos address new problems or concerns.
    569  1.1  christos 
    570  1.1  christos   Each version is given a distinguishing version number.  If the
    571  1.1  christos Program specifies that a certain numbered version of the GNU General
    572  1.1  christos Public License "or any later version" applies to it, you have the
    573  1.1  christos option of following the terms and conditions either of that numbered
    574  1.1  christos version or of any later version published by the Free Software
    575  1.1  christos Foundation.  If the Program does not specify a version number of the
    576  1.1  christos GNU General Public License, you may choose any version ever published
    577  1.1  christos by the Free Software Foundation.
    578  1.1  christos 
    579  1.1  christos   If the Program specifies that a proxy can decide which future
    580  1.1  christos versions of the GNU General Public License can be used, that proxy's
    581  1.1  christos public statement of acceptance of a version permanently authorizes you
    582  1.1  christos to choose that version for the Program.
    583  1.1  christos 
    584  1.1  christos   Later license versions may give you additional or different
    585  1.1  christos permissions.  However, no additional obligations are imposed on any
    586  1.1  christos author or copyright holder as a result of your choosing to follow a
    587  1.1  christos later version.
    588  1.1  christos 
    589  1.1  christos   15. Disclaimer of Warranty.
    590  1.1  christos 
    591  1.1  christos   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    592  1.1  christos APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    593  1.1  christos HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
    594  1.1  christos OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
    595  1.1  christos THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    596  1.1  christos PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
    597  1.1  christos IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    598  1.1  christos ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    599  1.1  christos 
    600  1.1  christos   16. Limitation of Liability.
    601  1.1  christos 
    602  1.1  christos   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    603  1.1  christos WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    604  1.1  christos THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
    605  1.1  christos GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
    606  1.1  christos USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
    607  1.1  christos DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
    608  1.1  christos PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
    609  1.1  christos EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
    610  1.1  christos SUCH DAMAGES.
    611  1.1  christos 
    612  1.1  christos   17. Interpretation of Sections 15 and 16.
    613  1.1  christos 
    614  1.1  christos   If the disclaimer of warranty and limitation of liability provided
    615  1.1  christos above cannot be given local legal effect according to their terms,
    616  1.1  christos reviewing courts shall apply local law that most closely approximates
    617  1.1  christos an absolute waiver of all civil liability in connection with the
    618  1.1  christos Program, unless a warranty or assumption of liability accompanies a
    619  1.1  christos copy of the Program in return for a fee.
    620  1.1  christos 
    621  1.1  christos                      END OF TERMS AND CONDITIONS
    622  1.1  christos 
    623  1.1  christos             How to Apply These Terms to Your New Programs

    625  1.1  christos   If you develop a new program, and you want it to be of the greatest
    626  1.1  christos possible use to the public, the best way to achieve this is to make it
    627  1.1  christos free software which everyone can redistribute and change under these terms.
    628  1.1  christos 
    629  1.1  christos   To do so, attach the following notices to the program.  It is safest
    630  1.1  christos to attach them to the start of each source file to most effectively
    631  1.1  christos state the exclusion of warranty; and each file should have at least
    632  1.1  christos the "copyright" line and a pointer to where the full notice is found.
    633  1.1  christos 
    634  1.1  christos     <one line to give the program's name and a brief idea of what it does.>

    650  1.1  christos Also add information on how to contact you by electronic and paper mail.
    651  1.1  christos 
    652  1.1  christos   If the program does terminal interaction, make it output a short
    653  1.1  christos notice like this when it starts in an interactive mode:
    654  1.1  christos 
    655  1.1  christos     <program>  Copyright (C) <year>  <name of author>
    656  1.1  christos     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    657  1.1  christos     This is free software, and you are welcome to redistribute it
    658  1.1  christos     under certain conditions; type `show c' for details.
    659  1.1  christos 
    660  1.1  christos The hypothetical commands `show w' and `show c' should show the appropriate
    661  1.1  christos parts of the General Public License.  Of course, your program's commands
    662  1.1  christos might be different; for a GUI interface, you would use an "about box".
    663  1.1  christos 
    664  1.1  christos   You should also get your employer (if you work as a programmer) or school,
    665  1.1  christos if any, to sign a "copyright disclaimer" for the program, if necessary.
