It will work on a uniprocessor, but the tests are much more likely to pass in the presence of serious problems. 1) Type ./configure --prefix=; make; make check in the directory containing unpacked source. The usual GNU build machinery is used, except that only static, but position-independent, libraries are normally built. On Windows, read README_win32.txt instead. 2) Applications should include atomic_ops.h. Nearly all operations are implemented by header files included from it. It is sometimes necessary, and always recommended to also link against libatomic_ops.a. To use the almost non-blocking stack or malloc implementations, see the corresponding README files, and also link against libatomic_gpl.a before linking against libatomic_ops.a. OVERVIEW: Atomic_ops.h defines a large collection of operations, each one of which is a combination of an (optional) atomic memory operation, and a memory barrier. Also defines associated feature-test macros to determine whether a particular operation is available on the current target hardware (either directly or by synthesis). This is an attempt to replace various existing files with similar goals, since they usually do not handle differences in memory barrier styles with sufficient generality. If this is included after defining AO_REQUIRE_CAS, then the package will make an attempt to emulate compare-and-swap in a way that (at least on Linux) should still be async-signal-safe. As a result, most other atomic operations will then be defined using the compare-and-swap emulation. This emulation is slow, since it needs to disable signals. And it needs to block in case of contention. If you care about performance on a platform that can't directly provide compare-and-swap, there are probably better alternatives. But this allows easy ports to some such platforms (e.g. PA_RISC). The option is ignored if compare-and-swap can be implemented directly. If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all atomic operations will be emulated with pthread locking. This is NOT async-signal-safe. And it is slow. It is intended primarily for debugging of the atomic_ops package itself. Note that the implementation reflects our understanding of real processor behavior. This occasionally diverges from the documented behavior. (E.g. the documented X86 behavior seems to be weak enough that it is impractical to use. Current real implementations appear to be much better behaved.) We of course are in no position to guarantee that future processors (even HPs) will continue to behave this way, though we hope they will. This is a work in progress. Corrections/additions for other platforms are greatly appreciated. It passes rudimentary tests on X86, Itanium, and Alpha. OPERATIONS: Most operations operate on values of type AO_t, which are unsigned integers whose size matches that of pointers on the given architecture. Exceptions are: - AO_test_and_set operates on AO_TS_t, which is whatever size the hardware supports with good performance. In some cases this is the length of a cache line. In some cases it is a byte. In many cases it is equivalent to AO_t. - A few operations are implemented on smaller or larger size integers. Such operations are indicated by the appropriate prefix: AO_char_... Operates on unsigned char values. AO_short_... Operates on unsigned short values. AO_int_... Operates on unsigned int values. (Currently a very limited selection of these is implemented. We're working on it.) The defined operations are all of the form AO_[_](). The component specifies an atomic memory operation. It may be one of the following, where the corresponding argument and result types are also specified: void nop() No atomic operation. The barrier may still be useful. AO_t load(const volatile AO_t * addr) Atomic load of *addr. void store(volatile AO_t * addr, AO_t new_val) Atomically store new_val to *addr. AO_t fetch_and_add(volatile AO_t *addr, AO_t incr) Atomically add incr to *addr, and return the original value of *addr. AO_t fetch_and_add1(volatile AO_t *addr) Equivalent to AO_fetch_and_add(addr, 1). AO_t fetch_and_sub1(volatile AO_t *addr) Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)). void and(volatile AO_t *addr, AO_t value) Atomically 'and' value into *addr. void or(volatile AO_t *addr, AO_t value) Atomically 'or' value into *addr. void xor(volatile AO_t *addr, AO_t value) Atomically 'xor' value into *addr. int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) Atomically compare *addr to old_val, and replace *addr by new_val if the first comparison succeeds. Returns nonzero if the comparison succeeded and *addr was updated. AO_t fetch_compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) Atomically compare *addr to old_val, and replace *addr by new_val if the first comparison succeeds; returns the original value of *addr. AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr) Atomically read the binary value at *addr, and set it. AO_TS_VAL_t is an enumeration type which includes two values AO_TS_SET and AO_TS_CLEAR. An AO_TS_t location is capable of holding an AO_TS_VAL_t, but may be much larger, as dictated by hardware constraints. Test_and_set logically sets the value to AO_TS_SET. It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro. AO_TS_t locations should be initialized to AO_TS_INITIALIZER. The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent. (On PA-RISC, AO_TS_SET is zero!) Test_and_set is a more limited version of compare_and_swap. Its only advantage is that it is more easily implementable on some hardware. It should thus be used if only binary test-and-set functionality is needed. If available, we also provide compare_and_swap operations that operate on wider values. Since standard data types for double width values may not be available, these explicitly take pairs of arguments for the new and/or old value. Unfortunately, there are two common variants, neither of which can easily and efficiently emulate the other. The first performs a comparison against the entire value being replaced, where the second replaces a double-width replacement, but performs a single-width comparison: int compare_double_and_swap_double(volatile AO_double_t * addr, AO_t old_val1, AO_t old_val2, AO_t new_val1, AO_t new_val2); int compare_and_swap_double(volatile AO_double_t * addr, AO_t old_val1, AO_t new_val1, AO_t new_val2); where AO_double_t is a structure containing AO_val1 and AO_val2 fields, both of type AO_t. For compare_and_swap_double, we compare against the val1 field. AO_double_t exists only if AO_HAVE_double_t is defined. ORDERING CONSTRAINTS: Each operation name also includes a suffix that specifies the associated ordering semantics. The ordering constraint limits reordering of this operation with respect to other atomic operations and ordinary memory references. The current implementation assumes that all memory references are to ordinary cacheable memory; the ordering guarantee is with respect to other threads or processes, not I/O devices. (Whether or not this distinction is important is platform-dependent.) Ordering suffixes are one of the following: : No memory barrier. A plain AO_nop() really does nothing. _release: Earlier operations must become visible to other threads before the atomic operation. _acquire: Later operations must become visible after this operation. _read: Subsequent reads must become visible after reads included in the atomic operation or preceding it. Rarely useful for clients? _write: Earlier writes become visible before writes during or after the atomic operation. Rarely useful for clients? _full: Ordered with respect to both earlier and later memory ops. AO_store_full or AO_nop_full are the normal ways to force a store to be ordered with respect to a later load. _release_write: Ordered with respect to earlier writes. This is normally implemented as either a _write or _release barrier. _acquire_read: Ordered with respect to later reads. This is normally implemented as either a _read or _acquire barrier. _dd_acquire_read: Ordered with respect to later reads that are data dependent on this one. This is needed on a pointer read, which is later dereferenced to read a second value, with the expectation that the second read is ordered after the first one. On most architectures, this is equivalent to no barrier. (This is very hard to define precisely. It should probably be avoided. A major problem is that optimizers tend to try to eliminate dependencies from the generated code, since dependencies force the hardware to execute the code serially.) We assume that if a store is data-dependent on a previous load, then the two are always implicitly ordered. It is possible to test whether AO_ is available on the current platform by checking whether AO_HAVE__ is defined as a macro. Note that we generally don't implement operations that are either meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write, AO_store_read). On some platforms (e.g. PA-RISC) many operations will remain undefined unless AO_REQUIRE_CAS is defined before including the package. When typed in the package build directory, the following command will print operations that are unimplemented on the platform: make test_atomic; ./test_atomic The following command generates a file "list_atomic.i" containing the macro expansions of all implemented operations on the platform: make list_atomic.i Future directions: It currently appears that something roughly analogous to this is very likely to become part of the C++0x standard. That effort has pointed out a number of issues that we expect to address there. Since some of the solutions really require compiler support, they may not be completely addressed here. Known issues include: We should be more precise in defining the semantics of the ordering constraints, and if and how we can guarantee sequential consistency. Dd_acquire_read is very hard or impossible to define in a way that cannot be invalidated by reasonably standard compiler transformations. There is probably no good reason to provide operations on standard integer types, since those may have the wrong alignment constraints. Example: If you want to initialize an object, and then "publish" a pointer to it in a global location p, such that other threads reading the new value of p are guaranteed to see an initialized object, it suffices to use AO_release_write(p, ...) to write the pointer to the object, and to retrieve it in other threads with AO_acquire_read(p). Platform notes: All X86: We quietly assume 486 or better. Microsoft compilers: Define AO_ASSUME_WINDOWS98 to get access to hardware compare-and-swap functionality. This relies on the InterlockedCompareExchange() function which was apparently not supported in Windows95. (There may be a better way to get access to this.) Gcc on x86: Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction. Currently this is appears to be of marginal benefit. libatomic-ops-7.4.2/doc/README_stack.txt0000644000175000017500000000756712330737456016425 0ustar ianwianwNote that the AO_stack implementation is licensed under the GPL, unlike the lower level routines. The header file atomic_ops_stack.h defines a linked stack abstraction. Stacks may be accessed by multiple concurrent threads. The implementation is 1-lock-free, i.e. it will continue to make progress if at most one thread becomes inactive while operating on the data structure. (The implementation can be built to be N-lock-free for any given N. But that seems to rarely be useful, especially since larger N involve some slowdown.) This makes it safe to access these data structures from non-reentrant signal handlers, provided at most one non-signal-handler thread is accessing the data structure at once. This latter condition can be ensured by acquiring an ordinary lock around the non-handler accesses to the data structure. For details see: Hans-J. Boehm, "An Almost Non-Blocking Stack", PODC 2004, http://portal.acm.org/citation.cfm?doid=1011767.1011774 (This is not exactly the implementation described there, since the interface was cleaned up in the interim. But it should perform very similarly.) We use a fully lock-free implementation when the underlying hardware makes that less expensive, i.e. when we have a double-wide compare-and-swap operation available. (The fully lock-free implementation uses an AO_t- sized version count, and assumes it does not wrap during the time any given operation is active. This seems reasonably safe on 32-bit hardware, and very safe on 64-bit hardware.) If a fully lock-free implementation is used, the macro AO_STACK_IS_LOCK_FREE will be defined. The implementation is interesting only because it allows reuse of existing nodes. This is necessary, for example, to implement a memory allocator. Since we want to leave the precise stack node type up to the client, we insist only that each stack node contains a link field of type AO_t. When a new node is pushed on the stack, the push operation expects to be passed the pointer to this link field, which will then be overwritten by this link field. Similarly, the pop operation returns a pointer to the link field of the object that previously was on the top of the stack. The cleanest way to use these routines is probably to define the stack node type with an initial AO_t link field, so that the conversion between the link-field pointer and the stack element pointer is just a compile-time cast. But other possibilities exist. (This would be cleaner in C++ with templates.) A stack is represented by an AO_stack_t structure. (This is normally 2 or 3 times the size of a pointer.) It may be statically initialized by setting it to AO_STACK_INITIALIZER, or dynamically initialized to an empty stack with AO_stack_init. There are only three operations for accessing stacks: void AO_stack_init(AO_stack_t *list); void AO_stack_push_release(AO_stack_t *list, AO_t *new_element); AO_t * AO_stack_pop_acquire(volatile AO_stack_t *list); We require that the objects pushed as list elements remain addressable as long as any push or pop operation are in progress. (It is OK for an object to be "pop"ped off a stack and "deallocated" with a concurrent "pop" on the same stack still in progress, but only if "deallocation" leaves the object addressable. The second "pop" may still read the object, but the value it reads will not matter.) We require that the headers (AO_stack objects) remain allocated and valid as long as any operations on them are still in-flight. We also provide macros AO_REAL_HEAD_PTR that converts an AO_stack_t to a pointer to the link field in the next element, and AO_REAL_NEXT_PTR that converts a link field to a real, dereferencable, pointer to the link field in the next element. This is intended only for debugging, or to traverse the list after modification has ceased. There is otherwise no guarantee that walking a stack using this macro will produce any kind of consistent picture of the data structure. libatomic-ops-7.4.2/doc/Makefile.am0000644000175000017500000000020112330737456015550 0ustar ianwianw# installed documentation # dist_pkgdata_DATA=LICENSING.txt README.txt README_stack.txt \ README_malloc.txt README_win32.txt libatomic-ops-7.4.2/doc/README_malloc.txt0000644000175000017500000000601612330737456016553 0ustar ianwianwThe libatomic_ops_gpl includes a simple almost-lock-free malloc implementation. This is intended as a safe way to allocate memory from a signal handler, or to allocate memory in the context of a library that does not know what thread library it will be used with. In either case locking is impossible. Note that the operations are only guaranteed to be 1-lock-free, i.e. a single blocked thread will not prevent progress, but multiple blocked threads may. To safely use these operations in a signal handler, the handler should be non-reentrant, i.e. it should not be interruptable by another handler using these operations. Furthermore use outside of signal handlers in a multithreaded application should be protected by a lock, so that at most one invocation may be interrupted by a signal. The header will define the macro "AO_MALLOC_IS_LOCK_FREE" on platforms on which malloc is completely lock-free, and hence these restrictions do not apply. In the presence of threads, but absence of contention, the time performance of this package should be as good, or slightly better than, most system malloc implementations. Its space performance is theoretically optimal (to within a constant factor), but probably quite poor in practice. In particular, no attempt is made to coalesce free small memory blocks. Something like Doug Lea's malloc is likely to use significantly less memory for complex applications. Performance on platforms without an efficient compare-and-swap implementation will be poor. This package was not designed for processor-scalability in the face of high allocation rates. If all threads happen to allocate different-sized objects, you might get lucky. Otherwise expect contention and false-sharing problems. If this is an issue, something like Maged Michael's algorithm (PLDI 2004) would be technically a far better choice. If you are concerned only with scalability, and not signal-safety, you might also consider using Hoard instead. We have seen a factor of 3 to 4 slowdown from the standard glibc malloc implementation with contention, even when the performance without contention was faster. (To make the implementation more scalable, one would need to replicate at least the free list headers, so that concurrent access is possible without cache conflicts.) Unfortunately there is no portable async-signal-safe way to obtain large chunks of memory from the OS. Based on reading of the source code, mmap-based allocation appears safe under Linux, and probably BSD variants. It is probably unsafe for operating systems built on Mach, such as Apple's Darwin. Without use of mmap, the allocator is limited to a fixed size, statically preallocated heap (2MB by default), and will fail to allocate objects above a certain size (just under 64K by default). Use of mmap to circumvent these limitations requires an explicit call. The entire interface to the AO_malloc package currently consists of: #include /* includes atomic_ops.h */ void *AO_malloc(size_t sz); void AO_free(void *p); void AO_malloc_enable_mmap(void); libatomic-ops-7.4.2/doc/README_win32.txt0000644000175000017500000000316512330737457016251 0ustar ianwianwMost of the atomic_ops functionality is available under Win32 with the Microsoft tools, but the build process currently is considerably more primitive than on Linux/Unix platforms. To build: 1) Go to the src directory in the distribution. 2) Make sure the Microsoft command-line tools (e.g. nmake) are available. 3) Run "nmake -f Makefile.msft". This should run some tests, which may print warnings about the types of the "Interlocked" functions. I haven't been able to make all versions of VC++ happy. If you know how to, please send a patch. 4) To compile applications, you will need to retain or copy the following pieces from the resulting src directory contents: "atomic_ops.h" - Header file defining low-level primitives. This includes files from: "atomic_ops"- Subdirectory containing implementation header files. "atomic_ops_stack.h" - Header file describing almost lock-free stack. "atomic_ops_malloc.h" - Header file describing almost lock-free malloc. "libatomic_ops_gpl.lib" - Library containing implementation of the above two (plus AO_pause() defined in atomic_ops.c). The atomic_ops.h implementation is entirely in the header files in Win32. Most clients of atomic_ops.h will need to define AO_ASSUME_WINDOWS98 before including it. Compare_and_swap is otherwise not available. Defining AO_ASSUME_VISTA will make compare_double_and_swap_double available as well.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.

You might find a more recent version [here](http://www.hboehm.info/gc/), or [here](https://github.com/ivmai/libatomic_ops). ## Overview This package provides semi-portable access to hardware-provided atomic memory update operations on a number architectures. These might allow you to write code: * That does more interesting things in signal handlers. * Makes more effective use of multiprocessors by allowing you to write clever lock-free code. Note that such code is very difficult to get right, and will unavoidably be less portable than lock-based code. It is also not always faster than lock-based code. But it may occasionally be a large performance win. * To experiment with new and much better thread programming paradigms, etc. For details and licensing restrictions see the files in the "doc" subdirectory. Please address bug reports to [mailing list](mailto:bdwgc@lists.opendylan.org). ## Installation and Usage The configuration and build scripts for this package were generated by Automake/Autoconf. "./configure; make; sudo make install" in this directory should work. For a more customized build, see the output of "./configure --help". Note that much of the content of this library is in the header files. However, two small libraries are built and installed: * libatomic_ops.a is a support library, which is not needed on some platforms. This is intended to be usable, under some mild restrictions, in free or proprietary code, as are all the header files. See doc/LICENSING.txt. * libatomic_ops_gpl.a contains some higher level facilities. This code is currently covered by the GPL. The contents currently correspond to the headers atomic_ops_stack.h and atomic_ops_malloc.h. ## Platform Specific Notes Win32/64: src/Makefile.msft contains a very simple Makefile for building and running tests and building the gpl library. The core atomic_ops implementation is entirely in header files. HP-UX/PA-RISC: aCC -Ae won't work as a C compiler, since it doesn't support inline assembly code. Use cc. ## Copyright & Warranty See doc/LICENSING.txt file. libatomic-ops-7.4.2/m4/0000755000175000017500000000000012330740343013263 5ustar ianwianwlibatomic-ops-7.4.2/m4/ltversion.m40000644000175000017500000000131312330737755015565 0ustar ianwianw# ltversion.m4 -- version numbers -*- Autoconf -*- # # Copyright (C) 2004, 2011-2013 Free Software Foundation, Inc. # Written by Scott James Remnant, 2004 # # This file is free software; the Free Software Foundation gives # unlimited permission to copy and/or distribute it, with or without # modifications, as long as this notice is preserved. # @configure_input@ # serial 4038 ltversion.m4 # This file is part of GNU Libtool m4_define([LT_PACKAGE_VERSION], [2.4.2.418]) m4_define([LT_PACKAGE_REVISION], [2.4.2.418]) AC_DEFUN([LTVERSION_VERSION], [macro_version='2.4.2.418' macro_revision='2.4.2.418' _LT_DECL(, macro_version, 0, [Which release of libtool.m4 was used?]) _LT_DECL(, macro_revision, 0) ]) libatomic-ops-7.4.2/m4/lt~obsolete.m40000644000175000017500000001377412330737757016132 0ustar ianwianw# lt~obsolete.m4 -- aclocal satisfying obsolete definitions. -*-Autoconf-*- # # Copyright (C) 2004-2005, 2007, 2009, 2011-2013 Free Software # Foundation, Inc. # Written by Scott James Remnant, 2004. # # This file is free software; the Free Software Foundation gives # unlimited permission to copy and/or distribute it, with or without # modifications, as long as this notice is preserved. # serial 5 lt~obsolete.m4 # These exist entirely to fool aclocal when bootstrapping libtool. # # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN), # which have later been changed to m4_define as they aren't part of the # exported API, or moved to Autoconf or Automake where they belong. # # The trouble is, aclocal is a bit thick.

Preamble The licenses for most software are designed to take away your freedom to share and change it. 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. GNU GENERAL PUBLIC LICENSE 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 How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'.
