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/sysfsutils/cmd/Makefile.am b/sysfsutils/cmd/Makefile.am deleted file mode 100644 index 1d10bba..0000000 --- a/sysfsutils/cmd/Makefile.am +++ /dev/null @@ -1,7 +0,0 @@ -bin_PROGRAMS = systool -systool_SOURCES = systool.c names.c names.h -INCLUDES = -I../include -LDADD = ../lib/libsysfs.la -EXTRA_CFLAGS = @EXTRA_CFLAGS@ -AM_CFLAGS = -Wall -W -Wstrict-prototypes $(EXTRA_CFLAGS) - diff --git a/sysfsutils/cmd/Makefile.in b/sysfsutils/cmd/Makefile.in deleted file mode 100644 index 960fa78..0000000 --- a/sysfsutils/cmd/Makefile.in +++ /dev/null @@ -1,453 +0,0 @@ -# Makefile.in generated by automake 1.9.6 from Makefile.am. -# @configure_input@ - -# Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, -# 2003, 2004, 2005 Free Software Foundation, Inc. -# This Makefile.in is free software;
