    Subject: [PATCH InfoSlicer] Remove wrapper around sugar-toolkit SL #3743
    
    This wrapper was used to allow compatibility with old versions of
    Sugar. I'm removing it to start the port to Gtk3 of InfoSlicer

    1                     GNU GENERAL PUBLIC LICENSE
    2                        Version 2, June 1991
    3 
    4  Copyright (C) 1989, 1991 Free Software Foundation, Inc.
    5      51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
    6  Everyone is permitted to copy and distribute verbatim copies
    7  of this license document, but changing it is not allowed.
    8 
    9                             Preamble
    10 
    11   The licenses for most software are designed to take away your
    12 freedom to share and change it.  By contrast, the GNU General Public
    13 License is intended to guarantee your freedom to share and change free
    14 software--to make sure the software is free for all its users.  This
    15 General Public License applies to most of the Free Software
    16 Foundation's software and to any other program whose authors commit to
    17 using it.  (Some other Free Software Foundation software is covered by
    18 the GNU Library General Public License instead.)  You can apply it to
    19 your programs, too.
    20 
    21   When we speak of free software, we are referring to freedom, not
    22 price.  Our General Public Licenses are designed to make sure that you
    23 have the freedom to distribute copies of free software (and charge for
    24 this service if you wish), that you receive source code or can get it
    25 if you want it, that you can change the software or use pieces of it
    26 in new free programs; and that you know you can do these things.
    27 
    28   To protect your rights, we need to make restrictions that forbid
    29 anyone to deny you these rights or to ask you to surrender the rights.
    30 These restrictions translate to certain responsibilities for you if you
    31 distribute copies of the software, or if you modify it.
    32 
    33   For example, if you distribute copies of such a program, whether
    34 gratis or for a fee, you must give the recipients all the rights that
    35 you have.  You must make sure that they, too, receive or can get the
    36 source code.  And you must show them these terms so they know their
    37 rights.
    38 
    39   We protect your rights with two steps: (1) copyright the software, and
    40 (2) offer you this license which gives you legal permission to copy,
    41 distribute and/or modify the software.
    42 
    43   Also, for each author's protection and ours, we want to make certain
    44 that everyone understands that there is no warranty for this free
    45 software.  If the software is modified by someone else and passed on, we
    46 want its recipients to know that what they have is not the original, so
    47 that any problems introduced by others will not reflect on the original
    48 authors' reputations.
    49 
    50   Finally, any free program is threatened constantly by software
    51 patents.  We wish to avoid the danger that redistributors of a free
    52 program will individually obtain patent licenses, in effect making the
    53 program proprietary.  To prevent this, we have made it clear that any
    54 patent must be licensed for everyone's free use or not licensed at all.
    55 
    56   The precise terms and conditions for copying, distribution and
    57 modification follow.
    58 
    590
    60                     GNU GENERAL PUBLIC LICENSE
    61    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    62 
    63   0. This License applies to any program or other work which contains
    64 a notice placed by the copyright holder saying it may be distributed
    65 under the terms of this General Public License.  The "Program", below,
    66 refers to any such program or work, and a "work based on the Program"
    67 means either the Program or any derivative work under copyright law:
    68 that is to say, a work containing the Program or a portion of it,
    69 either verbatim or with modifications and/or translated into another
    70 language.  (Hereinafter, translation is included without limitation in
    71 the term "modification".)  Each licensee is addressed as "you".
    72 
    73 Activities other than copying, distribution and modification are not
    74 covered by this License; they are outside its scope.  The act of
    75 running the Program is not restricted, and the output from the Program
    76 is covered only if its contents constitute a work based on the
    77 Program (independent of having been made by running the Program).
    78 Whether that is true depends on what the Program does.
    79 
    80   1. You may copy and distribute verbatim copies of the Program's
    81 source code as you receive it, in any medium, provided that you
    82 conspicuously and appropriately publish on each copy an appropriate
    83 copyright notice and disclaimer of warranty; keep intact all the
    84 notices that refer to this License and to the absence of any warranty;
    85 and give any other recipients of the Program a copy of this License
    86 along with the Program.
    87 
    88 You may charge a fee for the physical act of transferring a copy, and
    89 you may at your option offer warranty protection in exchange for a fee.
    90 
    91   2. You may modify your copy or copies of the Program or any portion
    92 of it, thus forming a work based on the Program, and copy and
    93 distribute such modifications or work under the terms of Section 1
    94 above, provided that you also meet all of these conditions:
    95 
    96     a) You must cause the modified files to carry prominent notices
    97     stating that you changed the files and the date of any change.
    98 
    99     b) You must cause any work that you distribute or publish, that in
    100     whole or in part contains or is derived from the Program or any
    101     part thereof, to be licensed as a whole at no charge to all third
    102     parties under the terms of this License.
    103 
    104     c) If the modified program normally reads commands interactively
    105     when run, you must cause it, when started running for such
    106     interactive use in the most ordinary way, to print or display an
    107     announcement including an appropriate copyright notice and a
    108     notice that there is no warranty (or else, saying that you provide
    109     a warranty) and that users may redistribute the program under
    110     these conditions, and telling the user how to view a copy of this
    111     License.  (Exception: if the Program itself is interactive but
    112     does not normally print such an announcement, your work based on
    113     the Program is not required to print an announcement.)
    114 
    1151
    116 These requirements apply to the modified work as a whole.  If
    117 identifiable sections of that work are not derived from the Program,
    118 and can be reasonably considered independent and separate works in
    119 themselves, then this License, and its terms, do not apply to those
    120 sections when you distribute them as separate works.  But when you
    121 distribute the same sections as part of a whole which is a work based
    122 on the Program, the distribution of the whole must be on the terms of
    123 this License, whose permissions for other licensees extend to the
    124 entire whole, and thus to each and every part regardless of who wrote it.
    125 
    126 Thus, it is not the intent of this section to claim rights or contest
    127 your rights to work written entirely by you; rather, the intent is to
    128 exercise the right to control the distribution of derivative or
    129 collective works based on the Program.
    130 
    131 In addition, mere aggregation of another work not based on the Program
    132 with the Program (or with a work based on the Program) on a volume of
    133 a storage or distribution medium does not bring the other work under
    134 the scope of this License.
    135 
    136   3. You may copy and distribute the Program (or a work based on it,
    137 under Section 2) in object code or executable form under the terms of
    138 Sections 1 and 2 above provided that you also do one of the following:
    139 
    140     a) Accompany it with the complete corresponding machine-readable
    141     source code, which must be distributed under the terms of Sections
    142     1 and 2 above on a medium customarily used for software interchange; or,
    143 
    144     b) Accompany it with a written offer, valid for at least three
    145     years, to give any third party, for a charge no more than your
    146     cost of physically performing source distribution, a complete
    147     machine-readable copy of the corresponding source code, to be
    148     distributed under the terms of Sections 1 and 2 above on a medium
    149     customarily used for software interchange; or,
    150 
    151     c) Accompany it with the information you received as to the offer
    152     to distribute corresponding source code.  (This alternative is
    153     allowed only for noncommercial distribution and only if you
    154     received the program in object code or executable form with such
    155     an offer, in accord with Subsection b above.)
    156 
    157 The source code for a work means the preferred form of the work for
    158 making modifications to it.  For an executable work, complete source
    159 code means all the source code for all modules it contains, plus any
    160 associated interface definition files, plus the scripts used to
    161 control compilation and installation of the executable.  However, as a
    162 special exception, the source code distributed need not include
    163 anything that is normally distributed (in either source or binary
    164 form) with the major components (compiler, kernel, and so on) of the
    165 operating system on which the executable runs, unless that component
    166 itself accompanies the executable.
    167 
    168 If distribution of executable or object code is made by offering
    169 access to copy from a designated place, then offering equivalent
    170 access to copy the source code from the same place counts as
    171 distribution of the source code, even though third parties are not
    172 compelled to copy the source along with the object code.
    173 
    1742
    175   4. You may not copy, modify, sublicense, or distribute the Program
    176 except as expressly provided under this License.  Any attempt
    177 otherwise to copy, modify, sublicense or distribute the Program is
    178 void, and will automatically terminate your rights under this License.
    179 However, parties who have received copies, or rights, from you under
    180 this License will not have their licenses terminated so long as such
    181 parties remain in full compliance.
    182 
    183   5. You are not required to accept this License, since you have not
    184 signed it.  However, nothing else grants you permission to modify or
    185 distribute the Program or its derivative works.  These actions are
    186 prohibited by law if you do not accept this License.  Therefore, by
    187 modifying or distributing the Program (or any work based on the
    188 Program), you indicate your acceptance of this License to do so, and
    189 all its terms and conditions for copying, distributing or modifying
    190 the Program or works based on it.
    191 
    192   6. Each time you redistribute the Program (or any work based on the
    193 Program), the recipient automatically receives a license from the
    194 original licensor to copy, distribute or modify the Program subject to
    195 these terms and conditions.  You may not impose any further
    196 restrictions on the recipients' exercise of the rights granted herein.
    197 You are not responsible for enforcing compliance by third parties to
    198 this License.
    199 
    200   7. If, as a consequence of a court judgment or allegation of patent
    201 infringement or for any other reason (not limited to patent issues),
    202 conditions are imposed on you (whether by court order, agreement or
    203 otherwise) that contradict the conditions of this License, they do not
    204 excuse you from the conditions of this License.  If you cannot
    205 distribute so as to satisfy simultaneously your obligations under this
    206 License and any other pertinent obligations, then as a consequence you
    207 may not distribute the Program at all.  For example, if a patent
    208 license would not permit royalty-free redistribution of the Program by
    209 all those who receive copies directly or indirectly through you, then
    210 the only way you could satisfy both it and this License would be to
    211 refrain entirely from distribution of the Program.
    212 
    213 If any portion of this section is held invalid or unenforceable under
    214 any particular circumstance, the balance of the section is intended to
    215 apply and the section as a whole is intended to apply in other
    216 circumstances.
    217 
    218 It is not the purpose of this section to induce you to infringe any
    219 patents or other property right claims or to contest validity of any
    220 such claims; this section has the sole purpose of protecting the
    221 integrity of the free software distribution system, which is
    222 implemented by public license practices.  Many people have made
    223 generous contributions to the wide range of software distributed
    224 through that system in reliance on consistent application of that
    225 system; it is up to the author/donor to decide if he or she is willing
    226 to distribute software through any other system and a licensee cannot
    227 impose that choice.
    228 
    229 This section is intended to make thoroughly clear what is believed to
    230 be a consequence of the rest of this License.
    231 
    2323
    233   8. If the distribution and/or use of the Program is restricted in
    234 certain countries either by patents or by copyrighted interfaces, the
    235 original copyright holder who places the Program under this License
    236 may add an explicit geographical distribution limitation excluding
    237 those countries, so that distribution is permitted only in or among
    238 countries not thus excluded.  In such case, this License incorporates
    239 the limitation as if written in the body of this License.
    240 
    241   9. The Free Software Foundation may publish revised and/or new versions
    242 of the General Public License from time to time.  Such new versions will
    243 be similar in spirit to the present version, but may differ in detail to

    245 
    246 Each version is given a distinguishing version number.  If the Program
    247 specifies a version number of this License which applies to it and "any
    248 later version", you have the option of following the terms and conditions
    249 either of that version or of any later version published by the Free
    250 Software Foundation.  If the Program does not specify a version number of
    251 this License, you may choose any version ever published by the Free Software
    252 Foundation.
    253 
    254   10. If you wish to incorporate parts of the Program into other free
    255 programs whose distribution conditions are different, write to the author
    256 to ask for permission.  For software which is copyrighted by the Free
    257 Software Foundation, write to the Free Software Foundation; we sometimes
    258 make exceptions for this.  Our decision will be guided by the two goals
    259 of preserving the free status of all derivatives of our free software and
    260 of promoting the sharing and reuse of software generally.
    261 
    262                             NO WARRANTY
    263 
    264   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
    265 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
    266 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
    267 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
    268 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
    269 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
    270 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
    271 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
    272 REPAIR OR CORRECTION.
    273 
    274   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    275 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
    276 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
    277 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
    278 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
    279 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
    280 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
    281 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
    282 POSSIBILITY OF SUCH DAMAGES.

    284                      END OF TERMS AND CONDITIONS
    285 
    2864
    287             How to Apply These Terms to Your New Programs
    288 
    289   If you develop a new program, and you want it to be of the greatest
    290 possible use to the public, the best way to achieve this is to make it
    291 free software which everyone can redistribute and change under these terms.
    292 
    293   To do so, attach the following notices to the program.  It is safest
    294 to attach them to the start of each source file to most effectively
    295 convey the exclusion of warranty; and each file should have at least
    296 the "copyright" line and a pointer to where the full notice is found.
    297 
    298     <one line to give the program's name and a brief idea of what it does.>
    299     Copyright (C) <year>  <name of author>
    300 
    301     This program is free software; you can redistribute it and/or modify
    302     it under the terms of the GNU General Public License as published by
    303     the Free Software Foundation; either version 2 of the License, or
    304     (at your option) any later version.
    305 
    306     This program is distributed in the hope that it will be useful,
    307     but WITHOUT ANY WARRANTY; without even the implied warranty of
    308     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    309     GNU General Public License for more details.
    310 
    311     You should have received a copy of the GNU General Public License
    312     along with this program; if not, write to the Free Software
    313     Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
    314 
    315 
    316 Also add information on how to contact you by electronic and paper mail.
    317 
    318 If the program is interactive, make it output a short notice like this
    319 when it starts in an interactive mode:
    320 
    321     Gnomovision version 69, Copyright (C) year  name of author
    322     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    323     This is free software, and you are welcome to redistribute it
    324     under certain conditions; type `show c' for details.
    325 
    326 The hypothetical commands `show w' and `show c' should show the appropriate
    327 parts of the General Public License.  Of course, the commands you use may
    328 be called something other than `show w' and `show c'; they could even be
    329 mouse-clicks or menu items--whatever suits your program.
    330 
    331 You should also get your employer (if you work as a programmer) or your
    332 school, if any, to sign a "copyright disclaimer" for the program, if
    333 necessary.  Here is a sample; alter the names:
    334 
    335   Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    336   `Gnomovision' (which makes passes at compilers) written by James Hacker.

    1 About
    2 -----
    3 
    4 A set of sugar components/libraries/etc to simplify writing activities.
    5 
    6 Cornerstone purposes for this project:
    7 * Total backwards compatibility for sugar-port API
    8 * Run on all sugar platforms beginning from 0.82
    9 
    10 In most cases sugar-port could be embedded to activity's directory tree.
    11 There is no need to include the whole sugar-port project only top level
    12 files/directories you are using directly - sugar-port's top level entities
    13 don't import each other.
