        Everyone is permitted to copy and distribute verbatim copies
 
     | 
  
  
     | 
    
        of this license document, but changing it is not allowed.

                                   Preamble
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The GNU General Public License is a free, copyleft license for
 
     | 
  
  
     | 
    
       software and other kinds of works.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The licenses for most software and other practical works are designed
 
     | 
  
  
     | 
    
       to take away your freedom to share and change the works.  By contrast,
 
     | 
  
  
     | 
    
       the GNU General Public License is intended to guarantee your freedom to
 
     | 
  
  
     | 
    
       share and change all versions of a program--to make sure it remains free
 
     | 
  
  
     | 
    
       software for all its users.  We, the Free Software Foundation, use the
 
     | 
  
  
     | 
    
       GNU General Public License for most of our software; it applies also to
 
     | 
  
  
     | 
    
       any other work released this way by its authors.  You can apply it to
 
     | 
  
  
     | 
    
       your programs, too.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         When we speak of free software, we are referring to freedom, not
 
     | 
  
  
     | 
    
       price.  Our General Public Licenses are designed to make sure that you
 
     | 
  
  
     | 
    
       have the freedom to distribute copies of free software (and charge for
 
     | 
  
  
     | 
    
       them if you wish), that you receive source code or can get it if you
 
     | 
  
  
     | 
    
       want it, that you can change the software or use pieces of it in new
 
     | 
  
  
     | 
    
       free programs, and that you know you can do these things.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         To protect your rights, we need to prevent others from denying you
 
     | 
  
  
     | 
    
       these rights or asking you to surrender the rights.  Therefore, you have
 
     | 
  
  
     | 
    
       certain responsibilities if you distribute copies of the software, or if
 
     | 
  
  
     | 
    
       you modify it: responsibilities to respect the freedom of others.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         For example, if you distribute copies of such a program, whether
 
     | 
  
  
     | 
    
       gratis or for a fee, you must pass on to the recipients the same
 
     | 
  
  
     | 
    
       freedoms that you received.  You must make sure that they, too, receive
 
     | 
  
  
     | 
    
       or can get the source code.  And you must show them these terms so they
 
     | 
  
  
     | 
    
       know their rights.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Developers that use the GNU GPL protect your rights with two steps:
 
     | 
  
  
     | 
    
       (1) assert copyright on the software, and (2) offer you this License
 
     | 
  
  
     | 
    
       giving you legal permission to copy, distribute and/or modify it.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         For the developers' and authors' protection, the GPL clearly explains
 
     | 
  
  
     | 
    
       that there is no warranty for this free software.  For both users' and
 
     | 
  
  
     | 
    
       authors' sake, the GPL requires that modified versions be marked as
 
     | 
  
  
     | 
    
       changed, so that their problems will not be attributed erroneously to
 
     | 
  
  
     | 
    
       authors of previous versions.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Some devices are designed to deny users access to install or run
 
     | 
  
  
     | 
    
       modified versions of the software inside them, although the manufacturer
 
     | 
  
  
     | 
    
       can do so.  This is fundamentally incompatible with the aim of
 
     | 
  
  
     | 
    
       protecting users' freedom to change the software.  The systematic
 
     | 
  
  
     | 
    
       pattern of such abuse occurs in the area of products for individuals to
 
     | 
  
  
     | 
    
       use, which is precisely where it is most unacceptable.  Therefore, we
 
     | 
  
  
     | 
    
       have designed this version of the GPL to prohibit the practice for those
 
     | 
  
  
     | 
    
       products.  If such problems arise substantially in other domains, we
 
     | 
  
  
     | 
    
       stand ready to extend this provision to those domains in future versions
 
     | 
  
  
     | 
    
       of the GPL, as needed to protect the freedom of users.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Finally, every program is threatened constantly by software patents.
 
     | 
  
  
     | 
    
       States should not allow patents to restrict development and use of
 
     | 
  
  
     | 
    
       software on general-purpose computers, but in those that do, we wish to
 
     | 
  
  
     | 
    
       avoid the special danger that patents applied to a free program could
 
     | 
  
  
     | 
    
       make it effectively proprietary.  To prevent this, the GPL assures that
 
     | 
  
  
     | 
    
       patents cannot be used to render the program non-free.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The precise terms and conditions for copying, distribution and
 
     | 
  
  
     | 
    
       modification follow.
 
     |

     | 
  
  
     | 
    
                              TERMS AND CONDITIONS
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         0. Definitions.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         "This License" refers to version 3 of the GNU General Public License.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         "Copyright" also means copyright-like laws that apply to other kinds of
 
     | 
  
  
     | 
    
       works, such as semiconductor masks.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         "The Program" refers to any copyrightable work licensed under this
 
     | 
  
  
     | 
    
       License.  Each licensee is addressed as "you".  "Licensees" and
 
     | 
  
  
     | 
    
       "recipients" may be individuals or organizations.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         To "modify" a work means to copy from or adapt all or part of the work
 
     | 
  
  
     | 
    
       in a fashion requiring copyright permission, other than the making of an
 
     | 
  
  
     | 
    
       exact copy.  The resulting work is called a "modified version" of the
 
     | 
  
  
     | 
    
       earlier work or a work "based on" the earlier work.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A "covered work" means either the unmodified Program or a work based
 
     | 
  
  
     | 
    
       on the Program.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         To "propagate" a work means to do anything with it that, without
 
     | 
  
  
     | 
    
       permission, would make you directly or secondarily liable for
 
     | 
  
  
     | 
    
       infringement under applicable copyright law, except executing it on a
 
     | 
  
  
     | 
    
       computer or modifying a private copy.  Propagation includes copying,
 
     | 
  
  
     | 
    
       distribution (with or without modification), making available to the
 
     | 
  
  
     | 
    
       public, and in some countries other activities as well.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         To "convey" a work means any kind of propagation that enables other
 
     | 
  
  
     | 
    
       parties to make or receive copies.  Mere interaction with a user through
 
     | 
  
  
     | 
    
       a computer network, with no transfer of a copy, is not conveying.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         An interactive user interface displays "Appropriate Legal Notices"
 
     | 
  
  
     | 
    
       to the extent that it includes a convenient and prominently visible
 
     | 
  
  
     | 
    
       feature that (1) displays an appropriate copyright notice, and (2)
 
     | 
  
  
     | 
    
       tells the user that there is no warranty for the work (except to the
 
     | 
  
  
     | 
    
       extent that warranties are provided), that licensees may convey the
 
     | 
  
  
     | 
    
       work under this License, and how to view a copy of this License.  If
 
     | 
  
  
     | 
    
       the interface presents a list of user commands or options, such as a
 
     | 
  
  
     | 
    
       menu, a prominent item in the list meets this criterion.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         1. Source Code.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The "source code" for a work means the preferred form of the work
 
     | 
  
  
     | 
    
       for making modifications to it.  "Object code" means any non-source
 
     | 
  
  
     | 
    
       form of a work.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A "Standard Interface" means an interface that either is an official
 
     | 
  
  
     | 
    
       standard defined by a recognized standards body, or, in the case of
 
     | 
  
  
     | 
    
       interfaces specified for a particular programming language, one that
 
     | 
  
  
     | 
    
       is widely used among developers working in that language.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The "System Libraries" of an executable work include anything, other
 
     | 
  
  
     | 
    
       than the work as a whole, that (a) is included in the normal form of
 
     | 
  
  
     | 
    
       packaging a Major Component, but which is not part of that Major
 
     | 
  
  
     | 
    
       Component, and (b) serves only to enable use of the work with that
 
     | 
  
  
     | 
    
       Major Component, or to implement a Standard Interface for which an
 
     | 
  
  
     | 
    
       implementation is available to the public in source code form.  A
 
     | 
  
  
     | 
    
       "Major Component", in this context, means a major essential component
 
     | 
  
  
     | 
    
       (kernel, window system, and so on) of the specific operating system
 
     | 
  
  
     | 
    
       (if any) on which the executable work runs, or a compiler used to
 
     | 
  
  
     | 
    
       produce the work, or an object code interpreter used to run it.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The "Corresponding Source" for a work in object code form means all
 
     | 
  
  
     | 
    
       the source code needed to generate, install, and (for an executable
 
     | 
  
  
     | 
    
       work) run the object code and to modify the work, including scripts to
 
     | 
  
  
     | 
    
       control those activities.  However, it does not include the work's
 
     | 
  
  
     | 
    
       System Libraries, or general-purpose tools or generally available free
 
     | 
  
  
     | 
    
       programs which are used unmodified in performing those activities but
 
     | 
  
  
     | 
    
       which are not part of the work.  For example, Corresponding Source
 
     | 
  
  
     | 
    
       includes interface definition files associated with source files for
 
     | 
  
  
     | 
    
       the work, and the source code for shared libraries and dynamically
 
     | 
  
  
     | 
    
       linked subprograms that the work is specifically designed to require,
 
     | 
  
  
     | 
    
       such as by intimate data communication or control flow between those
 
     | 
  
  
     | 
    
       subprograms and other parts of the work.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The Corresponding Source need not include anything that users
 
     | 
  
  
     | 
    
       can regenerate automatically from other parts of the Corresponding
 
     | 
  
  
     | 
    
       Source.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The Corresponding Source for a work in source code form is that
 
     | 
  
  
     | 
    
       same work.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         2. Basic Permissions.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         All rights granted under this License are granted for the term of
 
     | 
  
  
     | 
    
       copyright on the Program, and are irrevocable provided the stated
 
     | 
  
  
     | 
    
       conditions are met.  This License explicitly affirms your unlimited
 
     | 
  
  
     | 
    
       permission to run the unmodified Program.  The output from running a
 
     | 
  
  
     | 
    
       covered work is covered by this License only if the output, given its
 
     | 
  
  
     | 
    
       content, constitutes a covered work.  This License acknowledges your
 
     | 
  
  
     | 
    
       rights of fair use or other equivalent, as provided by copyright law.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may make, run and propagate covered works that you do not
 
     | 
  
  
     | 
    
       convey, without conditions so long as your license otherwise remains
 
     | 
  
  
     | 
    
       in force.  You may convey covered works to others for the sole purpose
 
     | 
  
  
     | 
    
       of having them make modifications exclusively for you, or provide you
 
     | 
  
  
     | 
    
       with facilities for running those works, provided that you comply with
 
     | 
  
  
     | 
    
       the terms of this License in conveying all material for which you do
 
     | 
  
  
     | 
    
       not control copyright.  Those thus making or running the covered works
 
     | 
  
  
     | 
    
       for you must do so exclusively on your behalf, under your direction
 
     | 
  
  
     | 
    
       and control, on terms that prohibit them from making any copies of

     | 
  
  
     | 
    
         Conveying under any other circumstances is permitted solely under
 
     | 
  
  
     | 
    
       the conditions stated below.  Sublicensing is not allowed; section 10
 
     | 
  
  
     | 
    
       makes it unnecessary.

         3. Protecting Users' Legal Rights From Anti-Circumvention Law.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         No covered work shall be deemed part of an effective technological
 
     | 
  
  
     | 
    
       measure under any applicable law fulfilling obligations under article
 
     | 
  
  
     | 
    
       11 of the WIPO copyright treaty adopted on 20 December 1996, or
 
     | 
  
  
     | 
    
       similar laws prohibiting or restricting circumvention of such
 
     | 
  
  
     | 
    
       measures.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         When you convey a covered work, you waive any legal power to forbid
 
     | 
  
  
     | 
    
       circumvention of technological measures to the extent such circumvention
 
     | 
  
  
     | 
    
       is effected by exercising rights under this License with respect to
 
     | 
  
  
     | 
    
       the covered work, and you disclaim any intention to limit operation or
 
     | 
  
  
     | 
    
       modification of the work as a means of enforcing, against the work's
 
     | 
  
  
     | 
    
       users, your or third parties' legal rights to forbid circumvention of
 
     | 
  
  
     | 
    
       technological measures.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         4. Conveying Verbatim Copies.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may convey verbatim copies of the Program's source code as you
 
     | 
  
  
     | 
    
       receive it, in any medium, provided that you conspicuously and
 
     | 
  
  
     | 
    
       appropriately publish on each copy an appropriate copyright notice;
 
     | 
  
  
     | 
    
       keep intact all notices stating that this License and any
 
     | 
  
  
     | 
    
       non-permissive terms added in accord with section 7 apply to the code;
 
     | 
  
  
     | 
    
       keep intact all notices of the absence of any warranty; and give all
 
     | 
  
  
     | 
    
       recipients a copy of this License along with the Program.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may charge any price or no price for each copy that you convey,
 
     | 
  
  
     | 
    
       and you may offer support or warranty protection for a fee.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         5. Conveying Modified Source Versions.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may convey a work based on the Program, or the modifications to
 
     | 
  
  
     | 
    
       produce it from the Program, in the form of source code under the
 
     | 
  
  
     | 
    
       terms of section 4, provided that you also meet all of these conditions:
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           a) The work must carry prominent notices stating that you modified
 
     | 
  
  
     | 
    
           it, and giving a relevant date.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           b) The work must carry prominent notices stating that it is
 
     | 
  
  
     | 
    
           released under this License and any conditions added under section
 
     | 
  
  
     | 
    
           7.  This requirement modifies the requirement in section 4 to
 
     | 
  
  
     | 
    
           "keep intact all notices".
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           c) You must license the entire work, as a whole, under this
 
     | 
  
  
     | 
    
           License to anyone who comes into possession of a copy.  This
 
     | 
  
  
     | 
    
           License will therefore apply, along with any applicable section 7
 
     | 
  
  
     | 
    
           additional terms, to the whole of the work, and all its parts,
 
     | 
  
  
     | 
    
           regardless of how they are packaged.  This License gives no
 
     | 
  
  
     | 
    
           permission to license the work in any other way, but it does not
 
     | 
  
  
     | 
    
           invalidate such permission if you have separately received it.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           d) If the work has interactive user interfaces, each must display
 
     | 
  
  
     | 
    
           Appropriate Legal Notices; however, if the Program has interactive
 
     | 
  
  
     | 
    
           interfaces that do not display Appropriate Legal Notices, your
 
     | 
  
  
     | 
    
           work need not make them do so.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A compilation of a covered work with other separate and independent
 
     | 
  
  
     | 
    
       works, which are not by their nature extensions of the covered work,
 
     | 
  
  
     | 
    
       and which are not combined with it such as to form a larger program,
 
     | 
  
  
     | 
    
       in or on a volume of a storage or distribution medium, is called an
 
     | 
  
  
     | 
    
       "aggregate" if the compilation and its resulting copyright are not
 
     | 
  
  
     | 
    
       used to limit the access or legal rights of the compilation's users
 
     | 
  
  
     | 
    
       beyond what the individual works permit.  Inclusion of a covered work
 
     | 
  
  
     | 
    
       in an aggregate does not cause this License to apply to the other
 
     | 
  
  
     | 
    
       parts of the aggregate.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         6. Conveying Non-Source Forms.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may convey a covered work in object code form under the terms
 
     | 
  
  
     | 
    
       of sections 4 and 5, provided that you also convey the
 
     | 
  
  
     | 
    
       machine-readable Corresponding Source under the terms of this License,
 
     | 
  
  
     | 
    
       in one of these ways:
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           a) Convey the object code in, or embodied in, a physical product
 
     | 
  
  
     | 
    
           (including a physical distribution medium), accompanied by the
 
     | 
  
  
     | 
    
           Corresponding Source fixed on a durable physical medium
 
     | 
  
  
     | 
    
           customarily used for software interchange.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           b) Convey the object code in, or embodied in, a physical product
 
     | 
  
  
     | 
    
           (including a physical distribution medium), accompanied by a
 
     | 
  
  
     | 
    
           written offer, valid for at least three years and valid for as
 
     | 
  
  
     | 
    
           long as you offer spare parts or customer support for that product
 
     | 
  
  
     | 
    
           model, to give anyone who possesses the object code either (1) a
 
     | 
  
  
     | 
    
           copy of the Corresponding Source for all the software in the
 
     | 
  
  
     | 
    
           product that is covered by this License, on a durable physical
 
     | 
  
  
     | 
    
           medium customarily used for software interchange, for a price no
 
     | 
  
  
     | 
    
           more than your reasonable cost of physically performing this
 
     | 
  
  
     | 
    
           conveying of source, or (2) access to copy the
 
     | 
  
  
     | 
    
           Corresponding Source from a network server at no charge.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           c) Convey individual copies of the object code with a copy of the
 
     | 
  
  
     | 
    
           written offer to provide the Corresponding Source.  This
 
     | 
  
  
     | 
    
           alternative is allowed only occasionally and noncommercially, and
 
     | 
  
  
     | 
    
           only if you received the object code with such an offer, in accord
 
     | 
  
  
     | 
    
           with subsection 6b.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           d) Convey the object code by offering access from a designated
 
     | 
  
  
     | 
    
           place (gratis or for a charge), and offer equivalent access to the
 
     | 
  
  
     | 
    
           Corresponding Source in the same way through the same place at no
 
     | 
  
  
     | 
    
           further charge.  You need not require recipients to copy the
 
     | 
  
  
     | 
    
           Corresponding Source along with the object code.  If the place to
 
     | 
  
  
     | 
    
           copy the object code is a network server, the Corresponding Source
 
     | 
  
  
     | 
    
           may be on a different server (operated by you or a third party)
 
     | 
  
  
     | 
    
           that supports equivalent copying facilities, provided you maintain
 
     | 
  
  
     | 
    
           clear directions next to the object code saying where to find the
 
     | 
  
  
     | 
    
           Corresponding Source.  Regardless of what server hosts the
 
     | 
  
  
     | 
    
           Corresponding Source, you remain obligated to ensure that it is
 
     | 
  
  
     | 
    
           available for as long as needed to satisfy these requirements.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           e) Convey the object code using peer-to-peer transmission, provided
 
     | 
  
  
     | 
    
           you inform other peers where the object code and Corresponding
 
     | 
  
  
     | 
    
           Source of the work are being offered to the general public at no
 
     | 
  
  
     | 
    
           charge under subsection 6d.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A separable portion of the object code, whose source code is excluded
 
     | 
  
  
     | 
    
       from the Corresponding Source as a System Library, need not be
 
     | 
  
  
     | 
    
       included in conveying the object code work.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A "User Product" is either (1) a "consumer product", which means any
 
     | 
  
  
     | 
    
       tangible personal property which is normally used for personal, family,
 
     | 
  
  
     | 
    
       or household purposes, or (2) anything designed or sold for incorporation
 
     | 
  
  
     | 
    
       into a dwelling.  In determining whether a product is a consumer product,
 
     | 
  
  
     | 
    
       doubtful cases shall be resolved in favor of coverage.  For a particular
 
     | 
  
  
     | 
    
       product received by a particular user, "normally used" refers to a
 
     | 
  
  
     | 
    
       typical or common use of that class of product, regardless of the status
 
     | 
  
  
     | 
    
       of the particular user or of the way in which the particular user
 
     | 
  
  
     | 
    
       actually uses, or expects or is expected to use, the product.  A product
 
     | 
  
  
     | 
    
       is a consumer product regardless of whether the product has substantial
 
     | 
  
  
     | 
    
       commercial, industrial or non-consumer uses, unless such uses represent
 
     | 
  
  
     | 
    
       the only significant mode of use of the product.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         "Installation Information" for a User Product means any methods,
 
     | 
  
  
     | 
    
       procedures, authorization keys, or other information required to install
 
     | 
  
  
     | 
    
       and execute modified versions of a covered work in that User Product from
 
     | 
  
  
     | 
    
       a modified version of its Corresponding Source.  The information must
 
     | 
  
  
     | 
    
       suffice to ensure that the continued functioning of the modified object
 
     | 
  
  
     | 
    
       code is in no case prevented or interfered with solely because
 
     | 
  
  
     | 
    
       modification has been made.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If you convey an object code work under this section in, or with, or
 
     | 
  
  
     | 
    
       specifically for use in, a User Product, and the conveying occurs as
 
     | 
  
  
     | 
    
       part of a transaction in which the right of possession and use of the
 
     | 
  
  
     | 
    
       User Product is transferred to the recipient in perpetuity or for a
 
     | 
  
  
     | 
    
       fixed term (regardless of how the transaction is characterized), the
 
     | 
  
  
     | 
    
       Corresponding Source conveyed under this section must be accompanied
 
     | 
  
  
     | 
    
       by the Installation Information.  But this requirement does not apply
 
     | 
  
  
     | 
    
       if neither you nor any third party retains the ability to install
 
     | 
  
  
     | 
    
       modified object code on the User Product (for example, the work has
 
     | 
  
  
     | 
    
       been installed in ROM).
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The requirement to provide Installation Information does not include a
 
     | 
  
  
     | 
    
       requirement to continue to provide support service, warranty, or updates
 
     | 
  
  
     | 
    
       for a work that has been modified or installed by the recipient, or for
 
     | 
  
  
     | 
    
       the User Product in which it has been modified or installed.  Access to a
 
     | 
  
  
     | 
    
       network may be denied when the modification itself materially and
 
     | 
  
  
     | 
    
       adversely affects the operation of the network or violates the rules and
 
     | 
  
  
     | 
    
       protocols for communication across the network.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Corresponding Source conveyed, and Installation Information provided,
 
     | 
  
  
     | 
    
       in accord with this section must be in a format that is publicly
 
     | 
  
  
     | 
    
       documented (and with an implementation available to the public in
 
     | 
  
  
     | 
    
       source code form), and must require no special password or key for
 
     | 
  
  
     | 
    
       unpacking, reading or copying.
 
     | 
  
  
     |

     | 
    
         7. Additional Terms.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         "Additional permissions" are terms that supplement the terms of this
 
     | 
  
  
     | 
    
       License by making exceptions from one or more of its conditions.
 
     | 
  
  
     | 
    
       Additional permissions that are applicable to the entire Program shall
 
     | 
  
  
     | 
    
       be treated as though they were included in this License, to the extent
 
     | 
  
  
     | 
    
       that they are valid under applicable law.  If additional permissions
 
     | 
  
  
     | 
    
       apply only to part of the Program, that part may be used separately
 
     | 
  
  
     | 
    
       under those permissions, but the entire Program remains governed by
 
     | 
  
  
     | 
    
       this License without regard to the additional permissions.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         When you convey a copy of a covered work, you may at your option
 
     | 
  
  
     | 
    
       remove any additional permissions from that copy, or from any part of
 
     | 
  
  
     | 
    
       it.  (Additional permissions may be written to require their own
 
     | 
  
  
     | 
    
       removal in certain cases when you modify the work.)  You may place
 
     | 
  
  
     | 
    
       additional permissions on material, added by you to a covered work,
 
     | 
  
  
     | 
    
       for which you have or can give appropriate copyright permission.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Notwithstanding any other provision of this License, for material you
 
     | 
  
  
     | 
    
       add to a covered work, you may (if authorized by the copyright holders of
 
     | 
  
  
     | 
    
       that material) supplement the terms of this License with terms:
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           a) Disclaiming warranty or limiting liability differently from the
 
     | 
  
  
     | 
    
           terms of sections 15 and 16 of this License; or
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           b) Requiring preservation of specified reasonable legal notices or
 
     | 
  
  
     | 
    
           author attributions in that material or in the Appropriate Legal
 
     | 
  
  
     | 
    
           Notices displayed by works containing it; or
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           c) Prohibiting misrepresentation of the origin of that material, or
 
     | 
  
  
     | 
    
           requiring that modified versions of such material be marked in
 
     | 
  
  
     | 
    
           reasonable ways as different from the original version; or
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           d) Limiting the use for publicity purposes of names of licensors or
 
     | 
  
  
     | 
    
           authors of the material; or
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           e) Declining to grant rights under trademark law for use of some
 
     | 
  
  
     | 
    
           trade names, trademarks, or service marks; or
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
           f) Requiring indemnification of licensors and authors of that
 
     | 
  
  
     | 
    
           material by anyone who conveys the material (or modified versions of
 
     | 
  
  
     | 
    
           it) with contractual assumptions of liability to the recipient, for
 
     | 
  
  
     | 
    
           any liability that these contractual assumptions directly impose on
 
     | 
  
  
     | 
    
           those licensors and authors.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         All other non-permissive additional terms are considered "further
 
     | 
  
  
     | 
    
       restrictions" within the meaning of section 10.  If the Program as you
 
     | 
  
  
     | 
    
       received it, or any part of it, contains a notice stating that it is
 
     | 
  
  
     | 
    
       governed by this License along with a term that is a further
 
     | 
  
  
     | 
    
       restriction, you may remove that term.  If a license document contains
 
     | 
  
  
     | 
    
       a further restriction but permits relicensing or conveying under this
 
     | 
  
  
     | 
    
       License, you may add to a covered work material governed by the terms
 
     | 
  
  
     | 
    
       of that license document, provided that the further restriction does
 
     | 
  
  
     | 
    
       not survive such relicensing or conveying.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If you add terms to a covered work in accord with this section, you
 
     | 
  
  
     | 
    
       must place, in the relevant source files, a statement of the
 
     | 
  
  
     | 
    
       additional terms that apply to those files, or a notice indicating
 
     | 
  
  
     | 
    
       where to find the applicable terms.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Additional terms, permissive or non-permissive, may be stated in the
 
     | 
  
  
     | 
    
       form of a separately written license, or stated as exceptions;
 
     | 
  
  
     | 
    
       the above requirements apply either way.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         8. Termination.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may not propagate or modify a covered work except as expressly
 
     | 
  
  
     | 
    
       provided under this License.  Any attempt otherwise to propagate or
 
     | 
  
  
     | 
    
       modify it is void, and will automatically terminate your rights under
 
     | 
  
  
     | 
    
       this License (including any patent licenses granted under the third
 
     | 
  
  
     | 
    
       paragraph of section 11).
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         However, if you cease all violation of this License, then your
 
     | 
  
  
     | 
    
       license from a particular copyright holder is reinstated (a)
 
     | 
  
  
     | 
    
       provisionally, unless and until the copyright holder explicitly and
 
     | 
  
  
     | 
    
       finally terminates your license, and (b) permanently, if the copyright
 
     | 
  
  
     | 
    
       holder fails to notify you of the violation by some reasonable means
 
     | 
  
  
     | 
    
       prior to 60 days after the cessation.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Moreover, your license from a particular copyright holder is
 
     | 
  
  
     | 
    
       reinstated permanently if the copyright holder notifies you of the
 
     | 
  
  
     | 
    
       violation by some reasonable means, this is the first time you have
 
     | 
  
  
     | 
    
       received notice of violation of this License (for any work) from that
 
     | 
  
  
     | 
    
       copyright holder, and you cure the violation prior to 30 days after
 
     | 
  
  
     | 
    
       your receipt of the notice.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Termination of your rights under this section does not terminate the
 
     | 
  
  
     | 
    
       licenses of parties who have received copies or rights from you under
 
     | 
  
  
     | 
    
       this License.  If your rights have been terminated and not permanently
 
     | 
  
  
     | 
    
       reinstated, you do not qualify to receive new licenses for the same
 
     | 
  
  
     | 
    
       material under section 10.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         9. Acceptance Not Required for Having Copies.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You are not required to accept this License in order to receive or
 
     | 
  
  
     | 
    
       run a copy of the Program.  Ancillary propagation of a covered work
 
     | 
  
  
     | 
    
       occurring solely as a consequence of using peer-to-peer transmission
 
     | 
  
  
     | 
    
       to receive a copy likewise does not require acceptance.  However,
 
     | 
  
  
     | 
    
       nothing other than this License grants you permission to propagate or
 
     | 
  
  
     | 
    
       modify any covered work.  These actions infringe copyright if you do
 
     | 
  
  
     | 
    
       not accept this License.  Therefore, by modifying or propagating a
 
     | 
  
  
     | 
    
       covered work, you indicate your acceptance of this License to do so.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         10. Automatic Licensing of Downstream Recipients.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Each time you convey a covered work, the recipient automatically
 
     | 
  
  
     | 
    
       receives a license from the original licensors, to run, modify and
 
     | 
  
  
     | 
    
       propagate that work, subject to this License.  You are not responsible
 
     | 
  
  
     | 
    
       for enforcing compliance by third parties with this License.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         An "entity transaction" is a transaction transferring control of an
 
     | 
  
  
     | 
    
       organization, or substantially all assets of one, or subdividing an
 
     | 
  
  
     | 
    
       organization, or merging organizations.  If propagation of a covered
 
     | 
  
  
     | 
    
       work results from an entity transaction, each party to that
 
     | 
  
  
     | 
    
       transaction who receives a copy of the work also receives whatever
 
     | 
  
  
     | 
    
       licenses to the work the party's predecessor in interest had or could
 
     | 
  
  
     | 
    
       give under the previous paragraph, plus a right to possession of the
 
     | 
  
  
     | 
    
       Corresponding Source of the work from the predecessor in interest, if
 
     | 
  
  
     | 
    
       the predecessor has it or can get it with reasonable efforts.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         You may not impose any further restrictions on the exercise of the
 
     | 
  
  
     | 
    
       rights granted or affirmed under this License.  For example, you may
 
     | 
  
  
     | 
    
       not impose a license fee, royalty, or other charge for exercise of
 
     | 
  
  
     | 
    
       rights granted under this License, and you may not initiate litigation
 
     | 
  
  
     | 
    
       (including a cross-claim or counterclaim in a lawsuit) alleging that
 
     | 
  
  
     | 
    
       any patent claim is infringed by making, using, selling, offering for
 
     | 
  
  
     | 
    
       sale, or importing the Program or any portion of it.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         11. Patents.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A "contributor" is a copyright holder who authorizes use under this
 
     | 
  
  
     | 
    
       License of the Program or a work on which the Program is based.  The
 
     | 
  
  
     | 
    
       work thus licensed is called the contributor's "contributor version".
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A contributor's "essential patent claims" are all patent claims
 
     | 
  
  
     | 
    
       owned or controlled by the contributor, whether already acquired or
 
     | 
  
  
     | 
    
       hereafter acquired, that would be infringed by some manner, permitted
 
     | 
  
  
     | 
    
       by this License, of making, using, or selling its contributor version,
 
     | 
  
  
     | 
    
       but do not include claims that would be infringed only as a
 
     | 
  
  
     | 
    
       consequence of further modification of the contributor version.  For
 
     | 
  
  
     | 
    
       purposes of this definition, "control" includes the right to grant
 
     | 
  
  
     | 
    
       patent sublicenses in a manner consistent with the requirements of
 
     | 
  
  
     | 
    
       this License.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Each contributor grants you a non-exclusive, worldwide, royalty-free
 
     | 
  
  
     | 
    
       patent license under the contributor's essential patent claims, to
 
     | 
  
  
     | 
    
       make, use, sell, offer for sale, import and otherwise run, modify and
 
     | 
  
  
     | 
    
       propagate the contents of its contributor version.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         In the following three paragraphs, a "patent license" is any express
 
     | 
  
  
     | 
    
       agreement or commitment, however denominated, not to enforce a patent
 
     | 
  
  
     | 
    
       (such as an express permission to practice a patent or covenant not to
 
     | 
  
  
     | 
    
       sue for patent infringement).  To "grant" such a patent license to a
 
     | 
  
  
     | 
    
       party means to make such an agreement or commitment not to enforce a
 
     | 
  
  
     | 
    
       patent against the party.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If you convey a covered work, knowingly relying on a patent license,
 
     | 
  
  
     | 
    
       and the Corresponding Source of the work is not available for anyone
 
     | 
  
  
     | 
    
       to copy, free of charge and under the terms of this License, through a
 
     | 
  
  
     | 
    
       publicly available network server or other readily accessible means,
 
     | 
  
  
     | 
    
       then you must either (1) cause the Corresponding Source to be so
 
     | 
  
  
     | 
    
       available, or (2) arrange to deprive yourself of the benefit of the
 
     | 
  
  
     | 
    
       patent license for this particular work, or (3) arrange, in a manner
 
     | 
  
  
     | 
    
       consistent with the requirements of this License, to extend the patent
 
     | 
  
  
     | 
    
       license to downstream recipients.  "Knowingly relying" means you have
 
     | 
  
  
     | 
    
       actual knowledge that, but for the patent license, your conveying the
 
     | 
  
  
     | 
    
       covered work in a country, or your recipient's use of the covered work
 
     | 
  
  
     | 
    
       in a country, would infringe one or more identifiable patents in that
 
     | 
  
  
     | 
    
       country that you have reason to believe are valid.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If, pursuant to or in connection with a single transaction or
 
     | 
  
  
     | 
    
       arrangement, you convey, or propagate by procuring conveyance of, a
 
     | 
  
  
     | 
    
       covered work, and grant a patent license to some of the parties
 
     | 
  
  
     | 
    
       receiving the covered work authorizing them to use, propagate, modify
 
     | 
  
  
     | 
    
       or convey a specific copy of the covered work, then the patent license
 
     | 
  
  
     | 
    
       you grant is automatically extended to all recipients of the covered
 
     | 
  
  
     | 
    
       work and works based on it.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         A patent license is "discriminatory" if it does not include within
 
     | 
  
  
     | 
    
       the scope of its coverage, prohibits the exercise of, or is
 
     | 
  
  
     | 
    
       conditioned on the non-exercise of one or more of the rights that are
 
     | 
  
  
     | 
    
       specifically granted under this License.  You may not convey a covered
 
     | 
  
  
     | 
    
       work if you are a party to an arrangement with a third party that is
 
     | 
  
  
     | 
    
       in the business of distributing software, under which you make payment
 
     | 
  
  
     | 
    
       to the third party based on the extent of your activity of conveying
 
     | 
  
  
     | 
    
       the work, and under which the third party grants, to any of the
 
     | 
  
  
     | 
    
       parties who would receive the covered work from you, a discriminatory
 
     | 
  
  
     | 
    
       patent license (a) in connection with copies of the covered work
 
     | 
  
  
     | 
    
       conveyed by you (or copies made from those copies), or (b) primarily
 
     | 
  
  
     | 
    
       for and in connection with specific products or compilations that
 
     | 
  
  
     | 
    
       contain the covered work, unless you entered into that arrangement,
 
     | 
  
  
     | 
    
       or that patent license was granted, prior to 28 March 2007.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Nothing in this License shall be construed as excluding or limiting
 
     | 
  
  
     | 
    
       any implied license or other defenses to infringement that may
 
     | 
  
  
     | 
    
       otherwise be available to you under applicable patent law.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         12. No Surrender of Others' Freedom.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If conditions are imposed on you (whether by court order, agreement or
 
     | 
  
  
     | 
    
       otherwise) that contradict the conditions of this License, they do not
 
     | 
  
  
     | 
    
       excuse you from the conditions of this License.  If you cannot convey a
 
     | 
  
  
     | 
    
       covered work so as to satisfy simultaneously your obligations under this
 
     | 
  
  
     | 
    
       License and any other pertinent obligations, then as a consequence you may
 
     | 
  
  
     | 
    
       not convey it at all.  For example, if you agree to terms that obligate you
 
     | 
  
  
     | 
    
       to collect a royalty for further conveying from those to whom you convey
 
     | 
  
  
     | 
    
       the Program, the only way you could satisfy both those terms and this
 
     | 
  
  
     | 
    
       License would be to refrain entirely from conveying the Program.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         13. Use with the GNU Affero General Public License.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Notwithstanding any other provision of this License, you have
 
     | 
  
  
     | 
    
       permission to link or combine any covered work with a work licensed
 
     | 
  
  
     | 
    
       under version 3 of the GNU Affero General Public License into a single
 
     | 
  
  
     | 
    
       combined work, and to convey the resulting work.  The terms of this
 
     | 
  
  
     | 
    
       License will continue to apply to the part which is the covered work,
 
     | 
  
  
     | 
    
       but the special requirements of the GNU Affero General Public License,
 
     | 
  
  
     | 
    
       section 13, concerning interaction through a network will apply to the
 
     | 
  
  
     | 
    
       combination as such.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         14. Revised Versions of this License.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         The Free Software Foundation may publish revised and/or new versions of
 
     | 
  
  
     | 
    
       the GNU General Public License from time to time.  Such new versions will
 
     | 
  
  
     | 
    
       be similar in spirit to the present version, but may differ in detail to
 
     | 
  
  
     | 
    
       address new problems or concerns.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Each version is given a distinguishing version number.  If the
 
     | 
  
  
     | 
    
       Program specifies that a certain numbered version of the GNU General
 
     | 
  
  
     | 
    
       Public License "or any later version" applies to it, you have the
 
     | 
  
  
     | 
    
       option of following the terms and conditions either of that numbered
 
     | 
  
  
     | 
    
       version or of any later version published by the Free Software
 
     | 
  
  
     | 
    
       Foundation.  If the Program does not specify a version number of the
 
     | 
  
  
     | 
    
       GNU General Public License, you may choose any version ever published
 
     | 
  
  
     | 
    
       by the Free Software Foundation.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If the Program specifies that a proxy can decide which future
 
     | 
  
  
     | 
    
       versions of the GNU General Public License can be used, that proxy's
 
     | 
  
  
     | 
    
       public statement of acceptance of a version permanently authorizes you
 
     | 
  
  
     | 
    
       to choose that version for the Program.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         Later license versions may give you additional or different
 
     | 
  
  
     | 
    
       permissions.  However, no additional obligations are imposed on any
 
     | 
  
  
     | 
    
       author or copyright holder as a result of your choosing to follow a
 
     | 
  
  
     | 
    
       later version.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         15. Disclaimer of Warranty.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 
     | 
  
  
     | 
    
       APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 
     | 
  
  
     | 
    
       HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 
     | 
  
  
     | 
    
       OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 
     | 
  
  
     | 
    
       THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 
     | 
  
  
     | 
    
       PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 
     | 
  
  
     | 
    
       IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 
     | 
  
  
     | 
    
       ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         16. Limitation of Liability.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 
     | 
  
  
     | 
    
       WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 
     | 
  
  
     | 
    
       THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 
     | 
  
  
     | 
    
       GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 
     | 
  
  
     | 
    
       USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 
     | 
  
  
     | 
    
       DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 
     | 
  
  
     | 
    
       PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 
     | 
  
  
     | 
    
       EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 
     | 
  
  
     | 
    
       SUCH DAMAGES.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         17. Interpretation of Sections 15 and 16.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If the disclaimer of warranty and limitation of liability provided
 
     | 
  
  
     | 
    
       above cannot be given local legal effect according to their terms,
 
     | 
  
  
     | 
    
       reviewing courts shall apply local law that most closely approximates
 
     | 
  
  
     | 
    
       an absolute waiver of all civil liability in connection with the
 
     | 
  
  
     | 
    
       Program, unless a warranty or assumption of liability accompanies a
 
     | 
  
  
     | 
    
       copy of the Program in return for a fee.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
                            END OF TERMS AND CONDITIONS

     | 
  
  
     | 
    
                   How to Apply These Terms to Your New Programs
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         If you develop a new program, and you want it to be of the greatest
 
     | 
  
  
     | 
    
       possible use to the public, the best way to achieve this is to make it
 
     | 
  
  
     | 
    
       free software which everyone can redistribute and change under these terms.
 
     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
         To do so, attach the following notices to the program.  It is safest
 
     | 
  
  
     | 
    
       to attach them to the start of each source file to most effectively
 
     | 
  
  
     | 
    
       state the exclusion of warranty; and each file should have at least
 
     | 
  
  
     | 
    
       the "copyright" line and a pointer to where the full notice is found.
 
     |

         If the program does terminal interaction, make it output a short
 
     | 
  
  
     | 
    
       notice like this when it starts in an interactive mode:
 
     |

           This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

           This is free software, and you are welcome to redistribute it
 
     |

     | 
  
  
     | 
    
       
     | 
  
  
     | 
    
       The hypothetical commands `show w' and `show c' should show the appropriate
 
     | 
  
  
     | 
    
       parts of the General Public License.  Of course, your program's commands
 
     | 
  
  
     | 
    
       might be different; for a GUI interface, you would use an "about box".

     | 
    
       
     | 
  
  
     | 
    
         You should also get your employer (if you work as a programmer) or school,
 
     | 
  
  
     | 
    
       if any, to sign a "copyright disclaimer" for the program, if necessary.

         The GNU General Public License does not permit incorporating your program
