CDL is now fully documented in the Component Writers -Guide.</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Template support for straightforward control of multiple -configuration elements, which can be used to provide easy access -to standard eCos configurations such as a debug stub boot ROM.</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Best of all, the source of the new configuration tools -and underlying libCDL technology has been open sourced under the -GNU Public License (GPL).</PARA> -</LISTITEM> -</ITEMIZEDLIST> -<PARA>A companion beta version of the eCos TCP/IP stack -has been released in conjunction with this release. The stack is -derived from the OpenBSD source base and provides UDP, TCP, ICMP, -BOOTP and DHCP protocol support on an IPv4 standards base. Device -driver support for Cirrus Logic EP72xx evaluation boards, Motorola -MBX, and StrongARM EBSA285 with Intel 82559 is included. The stack -and ethernet core support are distributed as configurable eCos packages. Platform -ethernet device drivers are distributed with the associated platform -HAL, but are naturally not useful without the ethernet core support -package.</PARA> -<PARA>A PCI bus support library has also been added that provides -generic PCI bus based device initialization, discovery, and configuration. -The library has been ported to both the VR4300 DDB-VRC4373 and StrongARM -EBSA285 development boards.</PARA> -<PARA>eCos also contains support for the POSIX Specification (ISO/IEC -9945-1)[POSIX]. This support follows EL/IX -level 1 in the functionality supplied [ELIX].</PARA> -<PARA>POSIX support is divided between the POSIX and the FILEIO -packages. The POSIX package provides support for threads, signals, -synchronization, timers and message queues. The FILEIO package provides -support for file and device I/O. The two packages may be -used together or separately, depending on configuration.</PARA> -<PARA>Also supplied with eCos is RedBoot; the standard bootstrap -and debugging environment for embedded systems from Red Hat. It -provides a wide set of tools for downloading and executing programs -on embedded target systems, as well as tools for manipulating the -target system's environment.</PARA> -<PARA>RedBoot's capabilities include: </PARA> -<ITEMIZEDLIST> -<LISTITEM> -<PARA>Serial and network (Ethernet) based debugging</PARA> -</LISTITEM> -<LISTITEM> -<PARA>FLASH management </PARA> -</LISTITEM> -<LISTITEM> -<PARA>Simple command line interface, available via serial or -Ethernet </PARA> -</LISTITEM> -<LISTITEM> -<PARA>Configurable and extensible, specifically adapted to the -target environment</PARA> -</LISTITEM> -</ITEMIZEDLIST> -<PARA>New architectures and platforms added in this release include: - </PARA> -<ITEMIZEDLIST> -<LISTITEM> -<PARA>ARM Thumb</PARA> -</LISTITEM> -<LISTITEM> -<PARA>ARM9</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Cirrus Logic CL-PS7111 and EP72xx</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Cogent CMA222 and CMA230 ARM boards</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Hitachi SH3</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Intel StrongARM</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Intel x86 PC</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Matsushita AM33</PARA> -</LISTITEM> -<LISTITEM> -<PARA>Motorola MBX evaluation board</PARA> -</LISTITEM> -<LISTITEM> -<PARA>NEC MIPS VR4300</PARA> -</LISTITEM> -<LISTITEM> -<PARA>NEC V8xx</PARA> -</LISTITEM> -</ITEMIZEDLIST> -<PARA>For further details of all the changes see the NEWS file in -the eCos sources.</PARA> -<PARA>Red Hat is dedicated to continued enhancement and maintenance -of the eCos system. Developers can look forward to upcoming releases -that further expand the architectural and board coverage, extend -the functionality of the TCP/IP stack, add a Linux version -of the GUI configuration tool, and add major new features such as a -Linux/Posix compatibility layer based on the upcoming EL/IX -standard - see <ULINK URL="http://sources.redhat.com/elix/">http://sources.redhat.com/elix/</ULINK> -for more details.</PARA> -</SECT1> - -<!-- ==================================================== --> - -<SECT1 ID="FOREWORD-ECOS-IN-A-NUTSHELL"> -<TITLE>eCos in a Nutshell</TITLE> -<PARA>eCos is an open source, configurable, portable, and - royalty-free embedded real-time operating system. The - following text expands on these core aspects that define - eCos.</PARA> -<PARA>eCos is provided as an open source runtime system - supported by the Red Hat GNUPro and GNU open source - development tools. Developers have full and unfettered access - to all aspects of the runtime system. No parts of it are - proprietary or hidden, and you are at liberty to examine, add - to, and modify the code as you deem necessary. These rights - are granted to you and protected by the Red Hat eCos Public - License (RHEPL). It also grants you the right to freely - develop and distribute applications based on eCos. You are not - expected or required to make your embedded applications or any - additional components that you develop freely available, - although we do require that you make publicly available any - modifications to the eCos code itself. Red Hat of course - welcomes all contributions back to eCos such as board ports, - device drivers and other components, as this helps the growth - and development of eCos, and is of benefit to the entire eCos - community.</PARA> -<PARA>One of the key technological innovations in eCos is our - configuration system. The configuration system allows the - application writer to impose their requirements on the - run-time components, both in terms of their functionality and - implementation, whereas traditionally the operating system has - constrained the application's own implementation. Essentially, - this enables eCos developers to create their own - application-specific operating system and makes eCos suitable - for a wide range of embedded uses. Configuration also ensures - that the resource footprint of eCos is minimized as all - unnecessary functionality and features are removed. The - configuration system also presents eCos as a component - architecture. This provides a standardized mechanism for - component suppliers to extend the functionality of eCos and - allows applications to be built from a wide set of optional - configurable run-time components. Components can be provided - from a variety of sources including: the standard eCos - release; commercial third party developers; open source - contributors; or additional optional components from Red - Hat.</PARA> -<PARA>The royalty-free nature of eCos means that you can develop -and deploy your application using the standard eCos release without -incurring any royalty charges. In addition, there are no up-front -license charges for the eCos runtime source code and associated -tools. We provide, without charge, everything necessary for basic embedded -applications development.</PARA> -<PARA>eCos is designed to be portable to a wide range of target -architectures and target platforms including 16, 32, and 64 bit -architectures, MPUs, MCUs and DSPs. The eCos kernel, libraries and -runtime components are layered on the Hardware Abstraction Layer -(HAL), and thus will run on any target once the HAL and relevant -device drivers have been ported to the target's processor -architecture and board. Currently eCos supports a large range of -different target architectures (ARM, Hitachi SH3, Intel x86, MIPS, -Matsushita AM3x, Intel StrongARM, NEC V850, Motorola PowerPC, and -SPARC) including many of the popular variants of these architectures -and evaluation boards. Many new ports are in development and will -be released as they become available.</PARA> -<PARA>eCos has been designed to support applications with real-time -requirements, providing features such as full preemptability, minimal -interrupt latencies, and all the necessary synchronization primitives, -scheduling policies, and interrupt handling mechanisms needed for -these type of applications. eCos also provides all the functionality -required for general embedded application support including device -drivers, memory management, exception handling, C, math libraries, -etc. In addition to runtime support, the eCos system includes all -the tools necessary to develop embedded applications, including -eCos software configuration and build tools, and GNU based compilers, -assemblers, linkers, debuggers, and simulators.</PARA> -<PARA>To get the most out of eCos you should visit the eCos open -source developers site: <ULINK URL="http://sources.redhat.com/ecos/">http://sources.redhat.com/ecos/</ULINK></PARA> -<PARA>The site is dedicated to the eCos developer community and - contains a rich set of resources including news, FAQ, online - documentation, installation guide, discussion and announcement - mailing lists, online problem report form, and runtime and - development tools downloads. We also support anonymous CVS and - WEBCVS access to provide you with direct access to the very - latest eCos source base. Complementing the open source - developers site is an eCos product site, featuring news, press - releases, details of our commercial engineering and support - services, products, and third party partner offerings. This is - located at <ULINK URL="http://www.redhat.com/embedded/technologies/ecos/">http://www.redhat.com/embedded/technologies/ecos/</ULINK></PARA> -<PARA>We have released eCos as open source software because we - believe that this is the most effective software development - model, and that it provides the greatest benefit to the embedded - developer community as a whole. As part of this endeavor, we - seek the input and participation of eCos developers in its - continuing evolution. Participation can take many forms - including:</PARA> -<ITEMIZEDLIST> -<LISTITEM> -<PARA>providing us with feedback on how eCos might be made more -useful to you - by taking part in the ongoing mailing list discussions -and by submitting problem reports covering bugs, documentation issues, -and missing features</PARA> -</LISTITEM> -<LISTITEM> -<PARA>contributing bug fixes and enhancement patches</PARA> -</LISTITEM> -<LISTITEM> -<PARA>contributing new code including device drivers, board -ports, libraries, and other runtime components</PARA> -</LISTITEM> -</ITEMIZEDLIST> -<PARA>Our long term aim is to make eCos a rich and ubiquitous standard -infrastructure for the development of deeply embedded applications. -This will be achieved in part by Red Hat's own efforts, -but also with the assistance of the eCos developer community cooperating -to improve eCos for all. I would like to take this opportunity to -extend our thanks to the many eCos developers who have already contributed -feedback, ideas, patches, and code that have augmented and improved this -release.</PARA> -<PARA>On behalf of the eCos team, welcome to the eCos developer - community.</PARA> -<LITERALLAYOUT><EMPHASIS ROLE="strong">Paul Beskeen, -Director of Engineering, eCos -November 2000</EMPHASIS></LITERALLAYOUT> -</SECT1> -</PREFACE><!-- Keep this comment at the end of the file -Local variables: -mode: sgml -sgml-omittag:nil -sgml-shorttag:t -sgml-namecase-general:t -sgml-general-insert-case:lower -sgml-minimize-attributes:nil -sgml-always-quote-attributes:t -sgml-indent-step:2 -sgml-indent-data:t -sgml-parent-document:("ecos-tutorial.sgml" "book" "preface") -sgml-exposed-tags:nil -sgml-local-catalogs:nil -sgml-local-ecat-files:nil -End: ---> -<CHAPTER ID="DOCUMENTATION-ROADMAP"> -<TITLE>Documentation Roadmap</TITLE> - -<!-- ==================================================== --> - -<SECT1 ID="GETTING-STARTED-WITH-ECOS"> -<TITLE>Getting Started with eCos</TITLE> -<VARIABLELIST> -<VARLISTENTRY> -<TERM><EMPHASIS>Release Notes</EMPHASIS></TERM> -<LISTITEM> -<PARA>Description of this release. </PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Installation Guide</EMPHASIS></TERM> -<LISTITEM> -<PARA>Hardware and software installation instructions, - including instructions on how to execute some prebuilt - tests to verify the installation.</PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Programming Tutorial</EMPHASIS></TERM> -<LISTITEM> -<PARA>A tutorial that gets you started running programs with - <EMPHASIS>eCos</EMPHASIS>.</PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Appendixes</EMPHASIS></TERM> -<LISTITEM> -<PARA>Extra information about the licensing terms - for <EMPHASIS>eCos</EMPHASIS>.</PARA> -</LISTITEM> -</VARLISTENTRY> -</VARIABLELIST> -</SECT1> - -<!-- ==================================================== --> - -<SECT1 ID="ECOS-USERS-GUIDE"> -<TITLE>eCos User's Guide</TITLE> -<VARIABLELIST> -<VARLISTENTRY> -<TERM><EMPHASIS>The eCos Configuration Tool</EMPHASIS></TERM> -<LISTITEM> -<PARA>A description of all features of the Configuration Tool. </PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Programming concepts and - techniques</EMPHASIS></TERM> -<LISTITEM> -<PARA>An explanation of the - <EMPHASIS>eCos</EMPHASIS> programming cycle, and a - description of some debugging facilities that - <EMPHASIS>eCos</EMPHASIS> offers. </PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Configuration and the Package - Repository</EMPHASIS></TERM> -<LISTITEM> -<PARA>Information on how to configure - <EMPHASIS>eCos</EMPHASIS> manually, including a reference - on the ecosconfig command, memory layouts, and information - on how to manage a package repository using the - <EMPHASIS>eCos Package Administration Tool</EMPHASIS>. - </PARA> -</LISTITEM> -</VARLISTENTRY> -</VARIABLELIST> -</SECT1> - -<!-- ==================================================== --> - -<SECT1 ID="ECOS-REFERENCE-MANUAL"> -<TITLE>eCos Reference Manual</TITLE> -<VARIABLELIST> -<VARLISTENTRY> -<TERM><EMPHASIS>Preliminaries</EMPHASIS></TERM> -<LISTITEM> -<PARA>An overview of the <EMPHASIS>eCos</EMPHASIS> - kernel and configurability system.</PARA> -</LISTITEM> -</VARLISTENTRY> -<VARLISTENTRY> -<TERM><EMPHASIS>Kernel APIs</EMPHASIS></TERM> -<LISTITEM> -<PARA>In-depth description of - <EMPHASIS>eCos</EMPHASIS>"s native C kernel API, the - µITRON API, the ISO standard C - library, and the <EMPHASIS>eCos</EMPHASIS> Hardware - Abstraction Layer (HAL).

Copyright (C) 1989, 1991 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - 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. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) <year> <name of author> - - 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. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs. If your program is a subroutine library, you may -consider it more useful to permit linking proprietary applications with the -library. If this is what you want to do, use the GNU Library General -Public License instead of this License. -</LITERALLAYOUT> -</APPENDIX> - <APPENDIX ID="THE-ECOS-COPYRIGHT-ASSIGNMENT-FORM"> - <docinfo> - <edition>Revision 1.2</edition> - </docinfo> - <TITLE>The eCos Copyright Assignment Form</TITLE> - <section> - <title>Rationale</title> - - <para>This preamble describes how to use the standard eCos copyright assignment -form. The rationale behind this assignment is to avoid any possible confusion -over the legal ownership of eCos, and to indemnify Red Hat and all eCos users -against copyright or patent claims on contributed code used within eCos. -Red Hat would be especially vulnerable, but all users and their eCos based -applications could be affected.</para> - - <para>In virtually all cases, all contributions to eCos for which there are -copyright assignments will be made available publically covered by the -<link linkend="GNU-GENERAL-PUBLIC-LICENSE">GNU General Public License</link> -plus an exception permitting linking eCos with proprietary code in order to make -the license more appropriate for embedded systems. The license provides a -guarantee that the contribution will remain freely available to all.</para> - - <para>This agreement gives Red Hat ownership of your changes but promises that -you will retain the right to use your contributed changes as you see fit. For convenience, -signing this agreement allows you to make further changes and additions and contribute -them as well if you so desire, without the necessity of signing a separate agreement. -There is however no requirement for you to do so. -</para> - - <para>Because employers often can claim ownership over things that employees -write, you may also have to get your employer to sign a disclaimer that says that -they have no claim to the changes you are contributing.</para> - - <para>Please read everything, and if you have any questions, email -<email>ecos-assign@redhat.com</email> for help.</para> - - <para>Thanks for your contribution to eCos!</para> - </section> - - <section id="how-to-assign-copyright"> - <title>How to assign copyright</title> - - <para>The way to assign copyright to Red Hat is to sign an assignment contract. This is -what makes Red Hat the legal copyright holder, so that Red Hat can register the -copyright on the new version. </para> - - <para>If you are employed as a programmer (even at a university), or have made an -agreement with your employer or school that gives them ownership of the software -you write, then Red Hat needs a signed letter from your employer disclaiming -rights to the contributed software. </para> - - <para>The disclaimer should be printed on the company's headed paper, and signed by an -officer of the company, or someone authorized to license the company's -intellectual property. Here is an example of wording that can be used for this -purpose: -<blockquote> - <para><replaceable><INSERT COMPANY NAME></replaceable> hereby disclaims all copyright -interest in the changes and enhancements made by <replaceable><INSERT YOUR NAME></replaceable> to eCos, -including any future revisions of these changes and enhancements.</para> - - <para><replaceable><INSERT COMPANY NAME></replaceable> affirms that it has no other intellectual -property interest that would undermine this release, or the use of eCos, and will do nothing -to undermine it in the future.</para> - - <para><replaceable><INSERT SIGNATURE OF OFFICER OF COMPANY></replaceable></para> - <para><replaceable><INSERT DATE></replaceable></para> - <para><replaceable><INSERT PRINTED NAME OF OFFICER OF COMPANY></replaceable></para> - <para><replaceable><INSERT TITLE OF OFFICER></replaceable></para> - </blockquote></para> - - <para>If your employer says they do have an intellectual property claim that could -conflict with the use of the program, then please contact Red Hat to discuss -possible next steps.</para> - - <para>Below is the usual assignment contract. You need to edit and replace -<replaceable><INSERT NAME OF CONTRIBUTOR></replaceable> with your full name. Please print a -copy, sign, date, and mail it to: -<address> -Legal Department (eCos Assignments) -Red Hat, Inc. -<pob>P.O.Box 13588</pob> -<street>Research Triangle Park</street> -<state>NC</state><postcode>27709-3588</postcode> -<country>USA</country></address> -</para> - <para>Don't forget to include the original signed copy of the employer's disclaimer.</para> - - <para>Please try to print the whole first page of the form on a single piece of paper. If it -doesn't fit on one printed page, put it on two sides of a single piece of paper, and -attach the second page of the form. Please write the date using letters rather than -numbers to avoid any confusion due to international day/month ordering -conventions. </para> - -<note><title>Note</title><para>This text is also available in the eCos software distribution, in the file -assign.txt.</para> - </note> - -<literallayout> - --------------------------------- Cut Here ------------------------------ - -eCos ASSIGNMENT - -For good and valuable consideration, receipt of which I acknowledge, I, -<replaceable>INSERT NAME OF CONTRIBUTOR</replaceable>, hereby transfer to Red Hat, Inc. -my entire right, title, and interest (including all rights under -copyright) in my changes and enhancements to the eCos Operating System and -associated software (herein called the "Software"), subject to the conditions -below.
