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

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

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