     19     Preamble
     20   </bridgehead>
     21   <para>
     22     The <acronym>GNU</acronym> General Public License is a free, copyleft
     23     license for software and other kinds of works.
     24   </para>
     25   <para>
     26     The licenses for most software and other practical works are designed to
     27     take away your freedom to share and change the works.  By contrast, the
     28     <acronym>GNU</acronym> General Public License is intended to guarantee your
     29     freedom to share and change all versions of a programto make sure it
     30     remains free software for all its users.  We, the Free Software Foundation,
     31     use the <acronym>GNU</acronym> General Public License for most of our
     32     software; it applies also to any other work released this way by its
     33     authors.  You can apply it to your programs, too.
     34   </para>
     35   <para>
     36     When we speak of free software, we are referring to freedom, not price.  Our
     37     General Public Licenses are designed to make sure that you have the freedom
     38     to distribute copies of free software (and charge for them if you wish),
     39     that you receive source code or can get it if you want it, that you can
     40     change the software or use pieces of it in new free programs, and that you
     41     know you can do these things.
     42   </para>
     43   <para>
     44     To protect your rights, we need to prevent others from denying you these
     45     rights or asking you to surrender the rights.  Therefore, you have certain
     46     responsibilities if you distribute copies of the software, or if you modify
     47     it: responsibilities to respect the freedom of others.
     48   </para>
     49   <para>
     50     For example, if you distribute copies of such a program, whether gratis or
     51     for a fee, you must pass on to the recipients the same freedoms that you
     52     received.  You must make sure that they, too, receive or can get the source
     53     code.  And you must show them these terms so they know their rights.
     54   </para>
     55   <para>
     56     Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym>
     57     protect your rights with two steps: (1) assert copyright on the software,
     58     and (2) offer you this License giving you legal permission to copy,
     59     distribute and/or modify it.
     60   </para>
     61   <para>
     62     For the developers and authors protection, the
     63     <acronym>GPL</acronym> clearly explains that there is no warranty for this
     64     free software.  For both users and authors sake, the
     65     <acronym>GPL</acronym> requires that modified versions be marked as changed,
     66     so that their problems will not be attributed erroneously to authors of
     67     previous versions.
     68   </para>
     69   <para>
     70     Some devices are designed to deny users access to install or run modified
     71     versions of the software inside them, although the manufacturer can do so.
     72     This is fundamentally incompatible with the aim of protecting users
     73     freedom to change the software.  The systematic pattern of such abuse occurs
     74     in the area of products for individuals to use, which is precisely where it
     75     is most unacceptable.  Therefore, we have designed this version of the
     76     <acronym>GPL</acronym> to prohibit the practice for those products.  If such
     77     problems arise substantially in other domains, we stand ready to extend this
     78     provision to those domains in future versions of the <acronym>GPL</acronym>,
     79     as needed to protect the freedom of users.
     80   </para>
     81   <para>
     82     Finally, every program is threatened constantly by software patents.  States
     83     should not allow patents to restrict development and use of software on
     84     general-purpose computers, but in those that do, we wish to avoid the
     85     special danger that patents applied to a free program could make it
     86     effectively proprietary.  To prevent this, the <acronym>GPL</acronym>
     87     assures that patents cannot be used to render the program non-free.

    104     Copyright also means copyright-like laws that apply to other

    107   <para>
    108     The Program refers to any copyrightable work licensed under
    109     this License.  Each licensee is addressed as you.
    110     Licensees and recipients may be individuals or
    111     organizations.
    112   </para>
    113   <para>
    114     To modify a work means to copy from or adapt all or part of
    115     the work in a fashion requiring copyright permission, other than the making
    116     of an exact copy.  The resulting work is called a modified
    117     version of the earlier work or a work based on the
    118     earlier work.
    119   </para>
    120   <para>
    121     A covered work means either the unmodified Program or a work
    122     based on the Program.
    123   </para>
    124   <para>
    125     To propagate a work means to do anything with it that, without
    126     permission, would make you directly or secondarily liable for infringement
    127     under applicable copyright law, except executing it on a computer or
    128     modifying a private copy.  Propagation includes copying, distribution (with
    129     or without modification), making available to the public, and in some
    130     countries other activities as well.
    131   </para>
    132   <para>
    133     To convey a work means any kind of propagation that enables
    134     other parties to make or receive copies.  Mere interaction with a user
    135     through a computer network, with no transfer of a copy, is not conveying.
    136   </para>
    137   <para>
    138     An interactive user interface displays Appropriate Legal
    139     Notices to the extent that it includes a convenient and prominently
    140     visible feature that (1) displays an appropriate copyright notice, and (2)
    141     tells the user that there is no warranty for the work (except to the extent
    142     that warranties are provided), that licensees may convey the work under this
    143     License, and how to view a copy of this License.  If the interface presents
    144     a list of user commands or options, such as a menu, a prominent item in the
    145     list meets this criterion.

    148     1. Source Code.
    149   </bridgehead>
    150   <para>
    151     The source code for a work means the preferred form of the
    152     work for making modifications to it.  Object code means any
    153     non-source form of a work.
    154   </para>
    155   <para>
    156     A Standard Interface means an interface that either is an
    157     official standard defined by a recognized standards body, or, in the case of
    158     interfaces specified for a particular programming language, one that is
    159     widely used among developers working in that language.
    160   </para>
    161   <para>
    162     The System Libraries of an executable work include anything,
    163     other than the work as a whole, that (a) is included in the normal form of
    164     packaging a Major Component, but which is not part of that Major Component,
    165     and (b) serves only to enable use of the work with that Major Component, or
    166     to implement a Standard Interface for which an implementation is available
    167     to the public in source code form.  A Major Component, in this
    168     context, means a major essential component (kernel, window system, and so
    169     on) of the specific operating system (if any) on which the executable work
    170     runs, or a compiler used to produce the work, or an object code interpreter
    171     used to run it.
    172   </para>
    173   <para>
    174     The Corresponding Source for a work in object code form means
    175     all the source code needed to generate, install, and (for an executable
    176     work) run the object code and to modify the work, including scripts to
    177     control those activities.  However, it does not include the works
    178     System Libraries, or general-purpose tools or generally available free
    179     programs which are used unmodified in performing those activities but which
    180     are not part of the work.  For example, Corresponding Source includes
    181     interface definition files associated with source files for the work, and
    182     the source code for shared libraries and dynamically linked subprograms that
    183     the work is specifically designed to require, such as by intimate data
    184     communication or control flow between those subprograms and other parts of
    185     the work.
    186   </para>
    187   <para>
    188     The Corresponding Source need not include anything that users can regenerate
    189     automatically from other parts of the Corresponding Source.

    192     The Corresponding Source for a work in source code form is that same work.

    212     in conveying all material for which you do not control copyright.  Those
    213     thus making or running the covered works for you must do so exclusively on
