 License, supplemented by the additional permissions listed below.

+-------------------------------------------------------------------------------
-  As used herein, "this License" refers to version 3 of the GNU Lesser
+Creative Commons Legal Code
 General Public License, and the "GNU GPL" refers to version 3 of the GNU
 General Public License.
-  "The Library" refers to a covered work governed by this License,
+Attribution-ShareAlike 3.0 Unported
 other than an Application or a Combined Work as defined below.
-  An "Application" is any work that makes use of an interface provided
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE

+    LEGAL SERVICES. DISTRIBUTION OF THIS LICENSE DOES NOT CREATE AN

+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES

    DAMAGES RESULTING FROM ITS USE.
  A "Combined Work" is a work produced by combining or linking an
 Application with the Library.  The particular version of the Library
 with which the Combined Work was made is also called the "Linked
 Version".
  The "Minimal Corresponding Source" for a Combined Work means the
 Corresponding Source for the Combined Work, excluding any source code
 for portions of the Combined Work that, considered in isolation, are
 based on the Application, and not on the Linked Version.
  The "Corresponding Application Code" for a Combined Work means the
 object code and/or source code for the Application, including any data
 and utility programs needed for reproducing the Combined Work from the
 Application, but excluding the System Libraries of the Combined Work.
  1. Exception to Section 3 of the GNU GPL.
  You may convey a covered work under sections 3 and 4 of this License
 without being bound by section 3 of the GNU GPL.
  2. Conveying Modified Versions.
  If you modify a copy of the Library, and, in your modifications, a
 facility refers to a function or data to be supplied by an Application
 that uses the facility (other than as an argument passed when the
 facility is invoked), then you may convey a copy of the modified
 version:
   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or
   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.
  3. Object Code Incorporating Material from Library Header Files.
  The object code form of an Application may incorporate material from
 a header file that is part of the Library.  You may convey such object
 code under terms of your choice, provided that, if the incorporated
 material is not limited to numerical parameters, data structure
 layouts and accessors, or small macros, inline functions and templates
 (ten or fewer lines in length), you do both of the following:
   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.
   b) Accompany the object code with a copy of the GNU GPL and this license
   document.
  4. Combined Works.
  You may convey a Combined Work under terms of your choice that,
 taken together, effectively do not restrict modification of the
 portions of the Library contained in the Combined Work and reverse
 engineering for debugging such modifications, if you also do each of
 the following:
   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.
   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.
   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.
   d) Do one of the following:
       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.
       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version.
   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)
  5. Combined Libraries.
  You may place library facilities that are a work based on the
 Library side by side in a single library together with other library
 facilities that are not Applications and are not covered by this
 License, and convey such a combined library under terms of your
 choice, if you do both of the following:
   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.
   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.
  6. Revised Versions of the GNU Lesser General Public License.
  The Free Software Foundation may publish revised and/or new versions
 of the GNU Lesser 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
 Library as you received it specifies that a certain numbered version
 of the GNU Lesser General Public License "or any later version"
 applies to it, you have the option of following the terms and
 conditions either of that published version or of any later version
 published by the Free Software Foundation. If the Library as you
 received it does not specify a version number of the GNU Lesser
 General Public License, you may choose any version of the GNU Lesser
 General Public License ever published by the Free Software Foundation.
  If the Library as you received it specifies that a proxy can decide
 whether future versions of the GNU Lesser General Public License shall
 apply, that proxy's public statement of acceptance of any version is
 permanent authorization for you to choose that version for the
 Library.

 Using Creative Commons Public Licenses
 Creative Commons public licenses provide a standard set of terms and
 conditions that creators and other rights holders may use to share
 original works of authorship and other material subject to copyright
 and certain other rights specified in the public license below. The
 following considerations are for informational purposes only, are not
 exhaustive, and do not form part of our licenses.
     Considerations for licensors: Our public licenses are
     intended for use by those authorized to give the public
     permission to use material in ways otherwise restricted by
     copyright and certain other rights. Our licenses are
     irrevocable. Licensors should read and understand the terms
     and conditions of the license they choose before applying it.
     Licensors should also secure all rights necessary before
     applying our licenses so that the public can reuse the
     material as expected. Licensors should clearly mark any
     material not subject to the license. This includes other CC-
     licensed material, or material used under an exception or
     limitation to copyright. More considerations for licensors:
 	wiki.creativecommons.org/Considerations_for_licensors
     Considerations for the public: By using one of our public
     licenses, a licensor grants the public permission to use the
     licensed material under specified terms and conditions. If
     the licensor's permission is not necessary for any reason--for
     example, because of any applicable exception or limitation to
     copyright--then that use is not regulated by the license. Our
     licenses grant only permissions under copyright and certain
     other rights that a licensor has authority to grant. Use of
     the licensed material may still be restricted for other
     reasons, including because others have copyright or other
     rights in the material. A licensor may make special requests,
     such as asking that all changes be marked or described.
     Although not required by our licenses, you are encouraged to
     respect those requests where reasonable. More considerations

 -- Dates growing functions.
 -- This is a bit complex, as the purpose is to find male flowers at horizontal distances of over
 -- 100 nodes. As searching such a large area is time consuming, this is optimized in four ways:
 -- - The search result (the locations of male trees) is cached, so that it can be used again
 -- - Only 1/9th of the desired area is searched at a time. A new search is only performed if no male
 --   flowers are found in the previously searched parts.
 -- - Search results are shared with other female palms nearby.
 -- - If previous searches for male palms have consumed too much CPU time, the search is skipped
 --   (This means no male palms will be found, and the pollination of the flowers affected will be
 --   delayed. If this happens repeatedly, eventually, the female flowers will wither...)
 -- A caching method was selected that is suited for the case where most date trees are long-lived,
 -- and where the number of trees nearby is limited:
 -- - Locations of male palms are stored as metadata for every female palm. This means that a player
 --   visiting a remote area with some date palms will not cause extensive searches for male palms as
 --   long overdue blossoming ABMs are triggered for every date palm.
 -- - Even when male palms *are* cut down, a cache refill will only be performed if the cached results do not
 --   contain a male palm with blossoms.
 -- The method will probably perform suboptimally:
 -- - If female palms are frequently chopped down and replanted.
 --   Freshly grown palms will need to search for male palms again
 --   (this is mitigated by the long blossoming interval, which increases the chance that search
 --    results have already been shared)
 -- - If an area contains a large number of male and female palms.
 --   In this area, every female palm will have an almost identical list of male palm locations
 --   as metadata.
 -- - If all male palms within range of a number of female palms have been chopped down (with possibly
 --   new ones planted). Although an attempt was made to share search results in this case as well,
 --   a number of similar searches will unavoidably be performed by the different female palms.
 -- - If no male palms are in range of a female palm. In that case, there will be frequent searches
 --   for newly-grown male palms.
 -- Search statistics - used to limit the search load.

 -- Usage:
 -- - Create a new world
 -- - Set world mapgen: v6
 -- - Set world seed: 2625051331357512570
 -- - Enable the moretrees mod
 -- - Edit the moretrees source
 --   - Disable all trees in default_settings.lua
 --   - Recommended: make saplings grow fast in default_settings.lua:
 --     sapling_interval = 5
 --     sapling_chance = 1
 --   - Apply the patch below to moretrees
 --     (so that jungle trees are always large, and differently-colored):
 --     use 'git apply --ignore-space-change'
 --   - Make sure this file (you are reading) will be loaded when minetest starts !
 --     (e.g. add 'dofile(modpath.."/screenshot.lua")' to init.lua)
 -- - Start minetest
 -- - Goto 700,y,-280 (approximately)
 -- - Make sure the world is loaded between x = 650 .. 780 and z = -350 .. -180
 -- - Give the chat command '/make-scene'
 -- - Wait & walk/fly around until all trees have grown
 -- - goto the platform at 780, 30, -277
 -- - Set the viewing range to 300, with fog enabled
 -- - Take a screenshot.

 The following is a search/replace command suitable for vi (/vim) or sed, to convert minetest log
 messages to equivalent lua commands:
 s/.*\(\(moretrees\|default\)[^ ]*\) at (\([-0-9]\+\),\([-0-9]\+\),\([-0-9]\+\)).*/\t\tminetest.place_node({x=\3, y=\4, z=\5}, {name="\1"})/
 E.g. a minetest log line of the following kind:
 		2016-07-03 11:30:50: ACTION[Server]: singleplayer places node moretrees:rubber_tree_sapling at  (760,5,-223)
 Becomes:
 		minetest.place_node({x=760, y=5, z=-223}, {name="moretrees:rubber_tree_sapling"})
 (Except that the example log line above has an extra space added, so it won't be converted)
 vi/vim users: Add the minetest log lines to this file, then enter the following command, with
 <expression> replaced with the search/replace expression above.
 	:%<expression>
 sed users: Add the minetest log lines to this file, then execute the following command at the shell
 prompt with <expression> replaced by the search/replace expression above. Don't forget the
 single-quotes.
 	sed '<expression>' < screenshot.lua > screenshot-new.lua
 Windows users: You're probably out of luck. And the effort of doing such a thing is probably
 larger anyway than the effort of copying an existing line and typing things manually.
