By contrast, the GNU General Public License is +intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This General +Public License applies to most of the Free Software Foundation's +software and to any other program whose authors commit to using it. +(Some other Free Software Foundation software is covered by the +GNU Library General Public License instead.) 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 +this service 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 make restrictions that forbid anyone +to deny you these rights or to ask you to surrender the rights. These +restrictions translate to certain responsibilities for you if you distribute +copies of the software, or if you modify it. + +For example, if you distribute copies of such a program, whether gratis +or for a fee, you must give the recipients all the rights that you have. 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. + +We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + +Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, +we want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + +Finally, any free program is threatened constantly by software patents. +We wish to avoid the danger that redistributors of a free program will +individually obtain patent licenses, in effect making the program +proprietary. To prevent this, we have made it clear that any patent must +be licensed for everyone's free use or not licensed at all. + +The precise terms and conditions for copying, distribution and +modification follow. + +TERMS AND CONDITIONS FOR +COPYING, DISTRIBUTION AND +MODIFICATION + +0. This License applies to any program or other work which contains a +notice placed by the copyright holder saying it may be distributed under +the terms of this General Public License. The "Program", below, refers +to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, either +verbatim or with modifications and/or translated into another language. +(Hereinafter, translation is included without limitation in the term +"modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of running +the Program is not restricted, and the output from the Program is +covered only if its contents constitute a work based on the Program +(independent of having been made by running the Program). Whether +that is true depends on what the Program does. + +1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices +that refer to this License and to the absence of any warranty; and give +any other recipients of the Program a copy of this License along with the +Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide a + warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but does + not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, and +can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based on +the Program, the distribution of the whole must be on the terms of this +License, whose permissions for other licensees extend to the entire +whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest your +rights to work written entirely by you; rather, the intent is to exercise the +right to control the distribution of derivative or collective works based +on the Program. + +In addition, mere aggregation of another work not based on the +Program with the Program (or with a work based on the Program) on a +volume of a storage or distribution medium does not bring the other +work under the scope of this License. + +3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding + machine-readable source code, which must be distributed under + the terms of Sections 1 and 2 above on a medium customarily + used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your cost + of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a + medium customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with + such an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to control +compilation and installation of the executable. However, as a special +exception, the source code distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies the +executable. + +If distribution of executable or object code is made by offering access to +copy from a designated place, then offering equivalent access to copy +the source code from the same place counts as distribution of the source +code, even though third parties are not compelled to copy the source +along with the object code. + +4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt otherwise +to copy, modify, sublicense or distribute the Program is void, and will +automatically terminate your rights under this License. However, parties +who have received copies, or rights, from you under this License will not +have their licenses terminated so long as such parties remain in full +compliance. + +5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and all +its terms and conditions for copying, distributing or modifying the +Program or works based on it. + +6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the original +licensor to copy, distribute or modify the Program subject to these terms +and conditions. You may not impose any further restrictions on the +recipients' exercise of the rights granted herein. You are not responsible +for enforcing compliance by third parties to this License. + +7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +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 distribute +so as to satisfy simultaneously your obligations under this License and +any other pertinent obligations, then as a consequence you may not +distribute the Program at all. For example, if a patent license would not +permit royalty-free redistribution of the Program by all those who +receive copies directly or indirectly through you, then the only way you +could satisfy both it and this License would be to refrain entirely from +distribution of the Program. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any patents +or other property right claims or to contest validity of any such claims; +this section has the sole purpose of protecting the integrity of the free +software distribution system, which is implemented by public license +practices. Many people have made generous contributions to the wide +range of software distributed through that system in reliance on +consistent application of that system; it is up to the author/donor to +decide if he or she is willing to distribute software through any other +system and a licensee cannot impose that choice. + +This section is intended to make thoroughly clear what is believed to be +a consequence of the rest of this License. + +8. If the distribution and/or use of the Program is restricted in certain +countries either by patents or by copyrighted interfaces, the original +copyright holder who places the Program under this License may add an +explicit geographical distribution limitation excluding those countries, so +that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + +9. The Free Software Foundation may publish revised and/or new +versions of the 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 a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number +of this License, you may choose any version ever published by the Free +Software Foundation. + +10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we +sometimes make exceptions for this. Our decision will be guided by the +two goals of preserving the free status of all derivatives of our free +software and of promoting the sharing and reuse of software generally. + +NO WARRANTY + +11. BECAUSE THE PROGRAM IS LICENSED FREE OF +CHARGE, 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. + +12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW +OR AGREED TO IN WRITING WILL ANY COPYRIGHT +HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE 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. + +END OF TERMS AND CONDITIONS diff --git a/weightmap/Changes b/weightmap/Changes new file mode 100644 index 0000000..6e9711a --- /dev/null +++ b/weightmap/Changes @@ -0,0 +1,7 @@ +Change log for PD external 'weightmap' + +v0.02 Thu, 02 Feb 2006 12:41:36 +0100 + + automake'd version + +v0.01 Sat Apr 20 21:52:03 CEST 2002 + + initial distributed version diff --git a/weightmap/Makefile.am b/weightmap/Makefile.am new file mode 100644 index 0000000..e1c1480 --- /dev/null +++ b/weightmap/Makefile.am @@ -0,0 +1,98 @@ +# File: ./Makefile.am +# Package: weightmap +# Description: +# + top-level automake file +# +# Process this file with Automake to create Makefile.in. +#----------------------------------------------------------------------- + +#----------------------------------------------------------------------- +# Options & Subdirectories +#----------------------------------------------------------------------- + +## --- automake options +#AUTOMAKE_OPTIONS = foreign dist-bzip2 dist-zip +AUTOMAKE_OPTIONS = foreign + +## --- recursion subdirectories +SUBDIRS = config src + +## --- pseudo-deps for '.SUFFIXES' +SUFFIXES = .pod .txt + +#----------------------------------------------------------------------- +# Variables: cleanup +#----------------------------------------------------------------------- +## --- mostlyclean: built by 'make' & commonly rebuilt +#MOSTLYCLEANFILES = + +## --- clean: built by 'make' +#CLEANFILES = + +## --- distclean: built by 'configure' +DISTCLEANFILES = \ + config.log \ + config.cache \ + config.status + +## -- maintainerclean: built by maintainer / by hand +MAINTAINERCLEANFILES = *~ \ + $(PODS:.pod=.txt) \ + Makefile Makefile.in \ + aclocal.m4 \ + configure \ + install-sh \ + stamp-h.in \ + config.h.in + +maintainer-clean-local: + rm -rf autom4te.cache + +#CVSCLEAN_SUBDIRS = $(SUBDIRS) + +#CVSCLEANFILES = Makefile.in Makefile + + +#----------------------------------------------------------------------- +# Additional Variables & Rules: PODS +#----------------------------------------------------------------------- +PODS = README.pod + +.pod.txt: + pod2text $< $@ + +all-local: $(PODS:.pod=.txt) + +#----------------------------------------------------------------------- +# Variables: distribution +#----------------------------------------------------------------------- + +## --- extra distribution files +EXTRA_DIST = \ + $(PODS:.pod=.txt) autogen.sh configure \ + README.cvs COPYING + +## --- recursion subdirectories for 'make dist' +#DIST_SUBDIRS = $(SUBDIRS) + +## --- dist-hook: when another 'Makefile.am' is overkill +#DISTHOOK_DIRS = foo +#DISTHOOK_FILES = foo/bar.txt foo/baz.txt +#dist-hook: +# for d in $(DISTHOOK_DIRS);
