+#   DESCRIPTION:  Read an MS excel SpreadsheetML document
+#                   extract the data to csv
+#
+#  REQUIREMENTS:  unzip | xsltproc | libxml | sqlite3 | gnu sed
+#          BUGS:  doesn't read formatting, macros
+#         NOTES:  does translate dates correctly! also handles null data
+#                 quotes and commas delimited, embedded quotes are doubled

+# 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
+# your copyrighted material outside their relationship with you.
+#
+#   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
