 restrictions on the recipients' exercise of the rights granted herein.    You may charge any price or no price for each copy that you convey,
 You are not responsible for enforcing compliance by third parties to  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.  this License.
   
   7. If, as a consequence of a court judgment or allegation of patent    Each contributor grants you a non-exclusive, worldwide, royalty-free
 infringement or for any other reason (not limited to patent issues),  patent license under the contributor's essential patent claims, to
 conditions are imposed on you (whether by court order, agreement or  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  otherwise) that contradict the conditions of this License, they do not

 certain countries either by patents or by copyrighted interfaces, the  
 original copyright holder who places the Program under this License  
 may add an explicit geographical distribution limitation excluding

 countries not thus excluded.  In such case, this License incorporates
