9# extract the data to csv
10#
11# REQUIREMENTS: unzip | xsltproc | libxml | sqlite3 | gnu sed | mktemp
12# BUGS: doesn't read formatting, macros
13# NOTES: does translate dates correctly! also handles null data
14# quotes and commas delimited, embedded quotes are doubled

40# Release notes:
41# 1.0 (2009/12/18) -- First release available to the public
42# 1.1 (2010/01/12) -- Improved date handling routine to look for all common date formats in Excel.
43# 1.2 (2010/08/31) -- Now uses /tmp, supports whitespace in filename, has a --help switch

51 Usage: $(basename $0) [-h|--help] [-c|--copyleft] [-d|--debug] [-v|--version] [-o|--overwrite]
52 [-t|--tmpdir] tempdir -x[|--xlsx] filename
53 -h, --help display this text
54 -c, --copyleft display copyright
55 -d, --debug show command output
56 -o, --overwrite overwrite already existing output files
57 -v, --version output version of this script
58 -t, --tmpdir dirname specify where temporary files should be created (currently in "${tmpdir}")
59 -x, --xlsx filename name of input file
60
61For those of us converting huge spreadsheets (or a lot of them):
62Create a ramdisk on OSX with the following code:
63NUMSECTORS=262144
64# 64mb = 131072 , 128mb = 262144 , 256mb = 524288 , 512mb = 1048576 , 1gb = 2097152
65mydev=\$(hdid -nomount ram://\$NUMSECTORS)
66newfs_hfs \$mydev
67[[ -d ~/sdb ]] || mkdir ~/sdb
68mount -t hfs \$mydev ~/sdb
69
70Then, use this mounted ramdisk for your temporary storage for $0.
71$0 -t ~/sdb -x filename
72On ubuntu, just use /dev/shm
73$0 -t /dev/shm -x filename
74
75Thanks to Hugo Mildeberger for cleaning up the temp dir code to make this work.

599# GNU GENERAL PUBLIC LICENSE
600# Version 3, 29 June 2007
601#
602# Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
603# Everyone is permitted to copy and distribute verbatim copies
604# of this license document, but changing it is not allowed.
605#
606# Preamble
607#
608# The GNU General Public License is a free, copyleft license for
609# software and other kinds of works.
610#
611# The licenses for most software and other practical works are designed
612# to take away your freedom to share and change the works. By contrast,
613# the GNU General Public License is intended to guarantee your freedom to
614# share and change all versions of a program--to make sure it remains free
615# software for all its users. We, the Free Software Foundation, use the
616# GNU General Public License for most of our software; it applies also to
617# any other work released this way by its authors. You can apply it to
618# your programs, too.
619#
620# When we speak of free software, we are referring to freedom, not
621# price. Our General Public Licenses are designed to make sure that you
622# have the freedom to distribute copies of free software (and charge for
623# them if you wish), that you receive source code or can get it if you
624# want it, that you can change the software or use pieces of it in new
625# free programs, and that you know you can do these things.
626#
627# To protect your rights, we need to prevent others from denying you
628# these rights or asking you to surrender the rights. Therefore, you have
629# certain responsibilities if you distribute copies of the software, or if
630# you modify it: responsibilities to respect the freedom of others.
631#
632# For example, if you distribute copies of such a program, whether
633# gratis or for a fee, you must pass on to the recipients the same
634# freedoms that you received. You must make sure that they, too, receive
635# or can get the source code. And you must show them these terms so they
636# know their rights.
637#
638# Developers that use the GNU GPL protect your rights with two steps:
639# (1) assert copyright on the software, and (2) offer you this License
640# giving you legal permission to copy, distribute and/or modify it.
641#
642# For the developers' and authors' protection, the GPL clearly explains
643# that there is no warranty for this free software. For both users' and
644# authors' sake, the GPL requires that modified versions be marked as
645# changed, so that their problems will not be attributed erroneously to
646# authors of previous versions.
647#
648# Some devices are designed to deny users access to install or run
649# modified versions of the software inside them, although the manufacturer
650# can do so. This is fundamentally incompatible with the aim of
651# protecting users' freedom to change the software. The systematic
652# pattern of such abuse occurs in the area of products for individuals to
653# use, which is precisely where it is most unacceptable. Therefore, we
654# have designed this version of the GPL to prohibit the practice for those
655# products. If such problems arise substantially in other domains, we
656# stand ready to extend this provision to those domains in future versions
657# of the GPL, as needed to protect the freedom of users.
658#
659# Finally, every program is threatened constantly by software patents.
660# States should not allow patents to restrict development and use of
661# software on general-purpose computers, but in those that do, we wish to
662# avoid the special danger that patents applied to a free program could
663# make it effectively proprietary. To prevent this, the GPL assures that
664# patents cannot be used to render the program non-free.
665#
666# The precise terms and conditions for copying, distribution and
667# modification follow.
668#
669# TERMS AND CONDITIONS
670#
671# 0. Definitions.
672#
673# "This License" refers to version 3 of the GNU General Public License.
674#
675# "Copyright" also means copyright-like laws that apply to other kinds of
676# works, such as semiconductor masks.
677#
678# "The Program" refers to any copyrightable work licensed under this
679# License. Each licensee is addressed as "you". "Licensees" and
680# "recipients" may be individuals or organizations.
681#
682# To "modify" a work means to copy from or adapt all or part of the work
683# in a fashion requiring copyright permission, other than the making of an
684# exact copy. The resulting work is called a "modified version" of the
685# earlier work or a work "based on" the earlier work.
686#
687# A "covered work" means either the unmodified Program or a work based
688# on the Program.
689#
690# To "propagate" a work means to do anything with it that, without
691# permission, would make you directly or secondarily liable for
692# infringement under applicable copyright law, except executing it on a
693# computer or modifying a private copy. Propagation includes copying,
694# distribution (with or without modification), making available to the
695# public, and in some countries other activities as well.
696#
697# To "convey" a work means any kind of propagation that enables other
698# parties to make or receive copies. Mere interaction with a user through
699# a computer network, with no transfer of a copy, is not conveying.
700#
701# An interactive user interface displays "Appropriate Legal Notices"
702# to the extent that it includes a convenient and prominently visible
703# feature that (1) displays an appropriate copyright notice, and (2)
704# tells the user that there is no warranty for the work (except to the
705# extent that warranties are provided), that licensees may convey the
706# work under this License, and how to view a copy of this License. If
707# the interface presents a list of user commands or options, such as a
708# menu, a prominent item in the list meets this criterion.
709#
710# 1. Source Code.
711#
712# The "source code" for a work means the preferred form of the work
713# for making modifications to it. "Object code" means any non-source
714# form of a work.
715#
716# A "Standard Interface" means an interface that either is an official
717# standard defined by a recognized standards body, or, in the case of
718# interfaces specified for a particular programming language, one that
719# is widely used among developers working in that language.
720#
721# The "System Libraries" of an executable work include anything, other
722# than the work as a whole, that (a) is included in the normal form of
723# packaging a Major Component, but which is not part of that Major
724# Component, and (b) serves only to enable use of the work with that
725# Major Component, or to implement a Standard Interface for which an
726# implementation is available to the public in source code form. A
727# "Major Component", in this context, means a major essential component
728# (kernel, window system, and so on) of the specific operating system
729# (if any) on which the executable work runs, or a compiler used to
730# produce the work, or an object code interpreter used to run it.
731#
732# The "Corresponding Source" for a work in object code form means all
733# the source code needed to generate, install, and (for an executable
734# work) run the object code and to modify the work, including scripts to
735# control those activities. However, it does not include the work's
736# System Libraries, or general-purpose tools or generally available free
737# programs which are used unmodified in performing those activities but
738# which are not part of the work. For example, Corresponding Source
739# includes interface definition files associated with source files for
740# the work, and the source code for shared libraries and dynamically
741# linked subprograms that the work is specifically designed to require,
742# such as by intimate data communication or control flow between those
743# subprograms and other parts of the work.
744#
745# The Corresponding Source need not include anything that users
746# can regenerate automatically from other parts of the Corresponding
747# Source.
748#
749# The Corresponding Source for a work in source code form is that
750# same work.
751#
752# 2. Basic Permissions.
753#
754# All rights granted under this License are granted for the term of
755# copyright on the Program, and are irrevocable provided the stated
756# conditions are met. This License explicitly affirms your unlimited
757# permission to run the unmodified Program. The output from running a
758# covered work is covered by this License only if the output, given its
759# content, constitutes a covered work. This License acknowledges your
760# rights of fair use or other equivalent, as provided by copyright law.
761#
762# You may make, run and propagate covered works that you do not
763# convey, without conditions so long as your license otherwise remains
764# in force. You may convey covered works to others for the sole purpose
765# of having them make modifications exclusively for you, or provide you
766# with facilities for running those works, provided that you comply with
767# the terms of this License in conveying all material for which you do
768# not control copyright. Those thus making or running the covered works
769# for you must do so exclusively on your behalf, under your direction
770# and control, on terms that prohibit them from making any copies of
771# your copyrighted material outside their relationship with you.
772#
773# Conveying under any other circumstances is permitted solely under
774# the conditions stated below. Sublicensing is not allowed; section 10
775# makes it unnecessary.
776#
777# 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
778#
779# No covered work shall be deemed part of an effective technological
780# measure under any applicable law fulfilling obligations under article
781# 11 of the WIPO copyright treaty adopted on 20 December 1996, or
782# similar laws prohibiting or restricting circumvention of such
783# measures.
784#
785# When you convey a covered work, you waive any legal power to forbid
786# circumvention of technological measures to the extent such circumvention
787# is effected by exercising rights under this License with respect to
788# the covered work, and you disclaim any intention to limit operation or
789# modification of the work as a means of enforcing, against the work's
790# users, your or third parties' legal rights to forbid circumvention of
791# technological measures.
792#
793# 4. Conveying Verbatim Copies.
794#
795# You may convey verbatim copies of the Program's source code as you
796# receive it, in any medium, provided that you conspicuously and
797# appropriately publish on each copy an appropriate copyright notice;
798# keep intact all notices stating that this License and any
799# non-permissive terms added in accord with section 7 apply to the code;
800# keep intact all notices of the absence of any warranty; and give all
801# recipients a copy of this License along with the Program.
802#
803# You may charge any price or no price for each copy that you convey,
804# and you may offer support or warranty protection for a fee.
805#
806# 5. Conveying Modified Source Versions.
807#
808# You may convey a work based on the Program, or the modifications to
809# produce it from the Program, in the form of source code under the
810# terms of section 4, provided that you also meet all of these conditions:
811#
812# a) The work must carry prominent notices stating that you modified
813# it, and giving a relevant date.
814#
815# b) The work must carry prominent notices stating that it is
816# released under this License and any conditions added under section
817# 7. This requirement modifies the requirement in section 4 to
818# "keep intact all notices".
819#
820# c) You must license the entire work, as a whole, under this
821# License to anyone who comes into possession of a copy. This
822# License will therefore apply, along with any applicable section 7
823# additional terms, to the whole of the work, and all its parts,
824# regardless of how they are packaged. This License gives no
825# permission to license the work in any other way, but it does not
826# invalidate such permission if you have separately received it.
827#
828# d) If the work has interactive user interfaces, each must display
829# Appropriate Legal Notices; however, if the Program has interactive
830# interfaces that do not display Appropriate Legal Notices, your
831# work need not make them do so.
832#
833# A compilation of a covered work with other separate and independent
834# works, which are not by their nature extensions of the covered work,
835# and which are not combined with it such as to form a larger program,
836# in or on a volume of a storage or distribution medium, is called an
837# "aggregate" if the compilation and its resulting copyright are not
838# used to limit the access or legal rights of the compilation's users
839# beyond what the individual works permit. Inclusion of a covered work
840# in an aggregate does not cause this License to apply to the other
841# parts of the aggregate.
842#
843# 6. Conveying Non-Source Forms.
844#
845# You may convey a covered work in object code form under the terms
846# of sections 4 and 5, provided that you also convey the
847# machine-readable Corresponding Source under the terms of this License,
848# in one of these ways:
849#
850# a) Convey the object code in, or embodied in, a physical product
851# (including a physical distribution medium), accompanied by the
852# Corresponding Source fixed on a durable physical medium
853# customarily used for software interchange.
854#
855# b) Convey the object code in, or embodied in, a physical product
856# (including a physical distribution medium), accompanied by a
857# written offer, valid for at least three years and valid for as
858# long as you offer spare parts or customer support for that product
859# model, to give anyone who possesses the object code either (1) a
860# copy of the Corresponding Source for all the software in the
861# product that is covered by this License, on a durable physical
862# medium customarily used for software interchange, for a price no
863# more than your reasonable cost of physically performing this
864# conveying of source, or (2) access to copy the
865# Corresponding Source from a network server at no charge.
866#
867# c) Convey individual copies of the object code with a copy of the
868# written offer to provide the Corresponding Source. This
869# alternative is allowed only occasionally and noncommercially, and
870# only if you received the object code with such an offer, in accord
871# with subsection 6b.
872#
873# d) Convey the object code by offering access from a designated
874# place (gratis or for a charge), and offer equivalent access to the
875# Corresponding Source in the same way through the same place at no
876# further charge. You need not require recipients to copy the
877# Corresponding Source along with the object code. If the place to
878# copy the object code is a network server, the Corresponding Source
879# may be on a different server (operated by you or a third party)
880# that supports equivalent copying facilities, provided you maintain
881# clear directions next to the object code saying where to find the
882# Corresponding Source. Regardless of what server hosts the
883# Corresponding Source, you remain obligated to ensure that it is
884# available for as long as needed to satisfy these requirements.
885#
886# e) Convey the object code using peer-to-peer transmission, provided
887# you inform other peers where the object code and Corresponding
888# Source of the work are being offered to the general public at no
889# charge under subsection 6d.
890#
891# A separable portion of the object code, whose source code is excluded
892# from the Corresponding Source as a System Library, need not be
893# included in conveying the object code work.
894#
895# A "User Product" is either (1) a "consumer product", which means any
896# tangible personal property which is normally used for personal, family,
897# or household purposes, or (2) anything designed or sold for incorporation
898# into a dwelling. In determining whether a product is a consumer product,
899# doubtful cases shall be resolved in favor of coverage. For a particular
900# product received by a particular user, "normally used" refers to a
901# typical or common use of that class of product, regardless of the status
902# of the particular user or of the way in which the particular user
903# actually uses, or expects or is expected to use, the product. A product
904# is a consumer product regardless of whether the product has substantial
905# commercial, industrial or non-consumer uses, unless such uses represent
906# the only significant mode of use of the product.
907#
908# "Installation Information" for a User Product means any methods,
909# procedures, authorization keys, or other information required to install
910# and execute modified versions of a covered work in that User Product from
911# a modified version of its Corresponding Source. The information must
912# suffice to ensure that the continued functioning of the modified object
913# code is in no case prevented or interfered with solely because
914# modification has been made.
915#
916# If you convey an object code work under this section in, or with, or
917# specifically for use in, a User Product, and the conveying occurs as
918# part of a transaction in which the right of possession and use of the
919# User Product is transferred to the recipient in perpetuity or for a
920# fixed term (regardless of how the transaction is characterized), the
921# Corresponding Source conveyed under this section must be accompanied
922# by the Installation Information. But this requirement does not apply
923# if neither you nor any third party retains the ability to install
924# modified object code on the User Product (for example, the work has
925# been installed in ROM).
926#
927# The requirement to provide Installation Information does not include a
928# requirement to continue to provide support service, warranty, or updates
929# for a work that has been modified or installed by the recipient, or for
930# the User Product in which it has been modified or installed. Access to a
931# network may be denied when the modification itself materially and
932# adversely affects the operation of the network or violates the rules and
933# protocols for communication across the network.
934#
935# Corresponding Source conveyed, and Installation Information provided,
936# in accord with this section must be in a format that is publicly
937# documented (and with an implementation available to the public in
938# source code form), and must require no special password or key for
939# unpacking, reading or copying.
940#
941# 7. Additional Terms.
942#
943# "Additional permissions" are terms that supplement the terms of this
944# License by making exceptions from one or more of its conditions.
945# Additional permissions that are applicable to the entire Program shall
946# be treated as though they were included in this License, to the extent
947# that they are valid under applicable law. If additional permissions
948# apply only to part of the Program, that part may be used separately
949# under those permissions, but the entire Program remains governed by
950# this License without regard to the additional permissions.
951#
952# When you convey a copy of a covered work, you may at your option
953# remove any additional permissions from that copy, or from any part of
954# it. (Additional permissions may be written to require their own
955# removal in certain cases when you modify the work.) You may place
956# additional permissions on material, added by you to a covered work,
957# for which you have or can give appropriate copyright permission.
958#
959# Notwithstanding any other provision of this License, for material you
960# add to a covered work, you may (if authorized by the copyright holders of
961# that material) supplement the terms of this License with terms:
962#
963# a) Disclaiming warranty or limiting liability differently from the
964# terms of sections 15 and 16 of this License; or
965#
966# b) Requiring preservation of specified reasonable legal notices or
967# author attributions in that material or in the Appropriate Legal
968# Notices displayed by works containing it; or
969#
970# c) Prohibiting misrepresentation of the origin of that material, or
971# requiring that modified versions of such material be marked in
972# reasonable ways as different from the original version; or
973#
974# d) Limiting the use for publicity purposes of names of licensors or
975# authors of the material; or
976#
977# e) Declining to grant rights under trademark law for use of some
978# trade names, trademarks, or service marks; or
979#
980# f) Requiring indemnification of licensors and authors of that
981# material by anyone who conveys the material (or modified versions of
982# it) with contractual assumptions of liability to the recipient, for
983# any liability that these contractual assumptions directly impose on
984# those licensors and authors.
985#
986# All other non-permissive additional terms are considered "further
987# restrictions" within the meaning of section 10. If the Program as you
988# received it, or any part of it, contains a notice stating that it is
989# governed by this License along with a term that is a further
990# restriction, you may remove that term. If a license document contains
991# a further restriction but permits relicensing or conveying under this
992# License, you may add to a covered work material governed by the terms
993# of that license document, provided that the further restriction does
994# not survive such relicensing or conveying.
995#
996# If you add terms to a covered work in accord with this section, you
997# must place, in the relevant source files, a statement of the
998# additional terms that apply to those files, or a notice indicating
999# where to find the applicable terms.
1000#
1001# Additional terms, permissive or non-permissive, may be stated in the
1002# form of a separately written license, or stated as exceptions;
1003# the above requirements apply either way.
1004#
1005# 8. Termination.
1006#
1007# You may not propagate or modify a covered work except as expressly
1008# provided under this License. Any attempt otherwise to propagate or
1009# modify it is void, and will automatically terminate your rights under
1010# this License (including any patent licenses granted under the third
1011# paragraph of section 11).
1012#
1013# However, if you cease all violation of this License, then your
1014# license from a particular copyright holder is reinstated (a)
1015# provisionally, unless and until the copyright holder explicitly and
1016# finally terminates your license, and (b) permanently, if the copyright
1017# holder fails to notify you of the violation by some reasonable means
1018# prior to 60 days after the cessation.
1019#
1020# Moreover, your license from a particular copyright holder is
1021# reinstated permanently if the copyright holder notifies you of the
1022# violation by some reasonable means, this is the first time you have
1023# received notice of violation of this License (for any work) from that
1024# copyright holder, and you cure the violation prior to 30 days after
1025# your receipt of the notice.
1026#
1027# Termination of your rights under this section does not terminate the
1028# licenses of parties who have received copies or rights from you under
1029# this License. If your rights have been terminated and not permanently
1030# reinstated, you do not qualify to receive new licenses for the same
1031# material under section 10.
1032#
1033# 9. Acceptance Not Required for Having Copies.
1034#
1035# You are not required to accept this License in order to receive or
1036# run a copy of the Program. Ancillary propagation of a covered work
1037# occurring solely as a consequence of using peer-to-peer transmission
1038# to receive a copy likewise does not require acceptance. However,
1039# nothing other than this License grants you permission to propagate or
1040# modify any covered work. These actions infringe copyright if you do
1041# not accept this License. Therefore, by modifying or propagating a
1042# covered work, you indicate your acceptance of this License to do so.
1043#
1044# 10. Automatic Licensing of Downstream Recipients.
1045#
1046# Each time you convey a covered work, the recipient automatically
1047# receives a license from the original licensors, to run, modify and
1048# propagate that work, subject to this License. You are not responsible
1049# for enforcing compliance by third parties with this License.
1050#
1051# An "entity transaction" is a transaction transferring control of an
1052# organization, or substantially all assets of one, or subdividing an
1053# organization, or merging organizations. If propagation of a covered
1054# work results from an entity transaction, each party to that
1055# transaction who receives a copy of the work also receives whatever
1056# licenses to the work the party's predecessor in interest had or could
1057# give under the previous paragraph, plus a right to possession of the
1058# Corresponding Source of the work from the predecessor in interest, if
1059# the predecessor has it or can get it with reasonable efforts.
1060#
1061# You may not impose any further restrictions on the exercise of the
1062# rights granted or affirmed under this License. For example, you may
1063# not impose a license fee, royalty, or other charge for exercise of
1064# rights granted under this License, and you may not initiate litigation
1065# (including a cross-claim or counterclaim in a lawsuit) alleging that
1066# any patent claim is infringed by making, using, selling, offering for
1067# sale, or importing the Program or any portion of it.
1068#
1069# 11. Patents.
1070#
1071# A "contributor" is a copyright holder who authorizes use under this
1072# License of the Program or a work on which the Program is based. The
1073# work thus licensed is called the contributor's "contributor version".
1074#
1075# A contributor's "essential patent claims" are all patent claims
1076# owned or controlled by the contributor, whether already acquired or
1077# hereafter acquired, that would be infringed by some manner, permitted
1078# by this License, of making, using, or selling its contributor version,
1079# but do not include claims that would be infringed only as a
1080# consequence of further modification of the contributor version. For
1081# purposes of this definition, "control" includes the right to grant
1082# patent sublicenses in a manner consistent with the requirements of
1083# this License.
1084#
1085# Each contributor grants you a non-exclusive, worldwide, royalty-free
1086# patent license under the contributor's essential patent claims, to
1087# make, use, sell, offer for sale, import and otherwise run, modify and
1088# propagate the contents of its contributor version.
1089#
1090# In the following three paragraphs, a "patent license" is any express
1091# agreement or commitment, however denominated, not to enforce a patent
1092# (such as an express permission to practice a patent or covenant not to
1093# sue for patent infringement). To "grant" such a patent license to a
1094# party means to make such an agreement or commitment not to enforce a
1095# patent against the party.
1096#
1097# If you convey a covered work, knowingly relying on a patent license,
1098# and the Corresponding Source of the work is not available for anyone
1099# to copy, free of charge and under the terms of this License, through a
1100# publicly available network server or other readily accessible means,
1101# then you must either (1) cause the Corresponding Source to be so
1102# available, or (2) arrange to deprive yourself of the benefit of the
1103# patent license for this particular work, or (3) arrange, in a manner
1104# consistent with the requirements of this License, to extend the patent
1105# license to downstream recipients. "Knowingly relying" means you have
1106# actual knowledge that, but for the patent license, your conveying the
1107# covered work in a country, or your recipient's use of the covered work
1108# in a country, would infringe one or more identifiable patents in that
1109# country that you have reason to believe are valid.
1110#
1111# If, pursuant to or in connection with a single transaction or
1112# arrangement, you convey, or propagate by procuring conveyance of, a
1113# covered work, and grant a patent license to some of the parties
1114# receiving the covered work authorizing them to use, propagate, modify
1115# or convey a specific copy of the covered work, then the patent license
1116# you grant is automatically extended to all recipients of the covered
1117# work and works based on it.
1118#
1119# A patent license is "discriminatory" if it does not include within
1120# the scope of its coverage, prohibits the exercise of, or is
1121# conditioned on the non-exercise of one or more of the rights that are
1122# specifically granted under this License. You may not convey a covered
1123# work if you are a party to an arrangement with a third party that is
1124# in the business of distributing software, under which you make payment
1125# to the third party based on the extent of your activity of conveying
1126# the work, and under which the third party grants, to any of the
1127# parties who would receive the covered work from you, a discriminatory
1128# patent license (a) in connection with copies of the covered work
1129# conveyed by you (or copies made from those copies), or (b) primarily
1130# for and in connection with specific products or compilations that
1131# contain the covered work, unless you entered into that arrangement,
1132# or that patent license was granted, prior to 28 March 2007.
1133#
1134# Nothing in this License shall be construed as excluding or limiting
1135# any implied license or other defenses to infringement that may
1136# otherwise be available to you under applicable patent law.
1137#
1138# 12. No Surrender of Others' Freedom.
1139#
1140# If conditions are imposed on you (whether by court order, agreement or
1141# otherwise) that contradict the conditions of this License, they do not
1142# excuse you from the conditions of this License. If you cannot convey a
1143# covered work so as to satisfy simultaneously your obligations under this
1144# License and any other pertinent obligations, then as a consequence you may
1145# not convey it at all. For example, if you agree to terms that obligate you
1146# to collect a royalty for further conveying from those to whom you convey
1147# the Program, the only way you could satisfy both those terms and this
1148# License would be to refrain entirely from conveying the Program.
1149#
1150# 13. Use with the GNU Affero General Public License.
1151#
1152# Notwithstanding any other provision of this License, you have
1153# permission to link or combine any covered work with a work licensed
1154# under version 3 of the GNU Affero General Public License into a single
1155# combined work, and to convey the resulting work. The terms of this
1156# License will continue to apply to the part which is the covered work,
1157# but the special requirements of the GNU Affero General Public License,
1158# section 13, concerning interaction through a network will apply to the
1159# combination as such.
1160#
1161# 14. Revised Versions of this License.
1162#
1163# The Free Software Foundation may publish revised and/or new versions of
1164# the GNU General Public License from time to time. Such new versions will
1165# be similar in spirit to the present version, but may differ in detail to
1166# address new problems or concerns.
1167#
1168# Each version is given a distinguishing version number. If the
1169# Program specifies that a certain numbered version of the GNU General
1170# Public License "or any later version" applies to it, you have the
1171# option of following the terms and conditions either of that numbered
1172# version or of any later version published by the Free Software
1173# Foundation. If the Program does not specify a version number of the
1174# GNU General Public License, you may choose any version ever published
1175# by the Free Software Foundation.
1176#
1177# If the Program specifies that a proxy can decide which future
1178# versions of the GNU General Public License can be used, that proxy's
1179# public statement of acceptance of a version permanently authorizes you
1180# to choose that version for the Program.
1181#
1182# Later license versions may give you additional or different
1183# permissions. However, no additional obligations are imposed on any
1184# author or copyright holder as a result of your choosing to follow a
1185# later version.
1186#
1187# 15. Disclaimer of Warranty.
1188#
1189# THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
1190# APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
1191# HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
1192# OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
1193# THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1194# PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
1195# IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
1196# ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1197#
1198# 16. Limitation of Liability.
1199#
1200# IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1201# WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
1202# THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
1203# GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
1204# USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
1205# DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
1206# PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
1207# EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
1208# SUCH DAMAGES.
1209#
1210# 17. Interpretation of Sections 15 and 16.
1211#
1212# If the disclaimer of warranty and limitation of liability provided
1213# above cannot be given local legal effect according to their terms,
1214# reviewing courts shall apply local law that most closely approximates
1215# an absolute waiver of all civil liability in connection with the
1216# Program, unless a warranty or assumption of liability accompanies a
1217# copy of the Program in return for a fee.
1218#
1219# END OF TERMS AND CONDITIONS
