-			 GNU libc SNAPSHOT SYSTEM
-			    (general info)
-			   Updated 1997-9-26
-
-WHAT ARE GNU libc SNAPSHOTS
----------------------------
-
-Snapshots are an "image" of the main glibc development tree, captured at a
-particular random instant in time.  When you use the snapshots, you should be
-able to maintain a local copy of libc that is no more than one day older than
-the official source tree used by the libc maintainers.
-
-The primary purpose of providing snapshots is to widen the group of motivated
-developers that would like to help test, debug, and enhance glibc, by providing
-you with access to the "latest and greatest" source.  This has several
-advantages, and several disadvantages.
-
-    First the advantages:
-
-    o	Once we have a large base of motivated testers using the snapshots,
-	this should provide good coverage across all currently supported
-	glibc hosts and targets.  If a new bug is introduced in glibc due to
-	fixing another bug or ongoing development, it should become
-	obvious much more quickly and get fixed before the next general
-	net release.  This should help to reduce the chances of glibc being
-	released to the general public with a major bug that went unnoticed
-	during the release cycle testing because they are machine dependent.
-	We hope to greatly improve glibc's stability and reliability by
-	involving more people and more execution environments in the
-	prerelease testing.
-
-    o	With access to the latest source, any diffs that you send to fix
-	bugs or add new features should be much easier for the glibc team
-	to merge into the official source base (after suitable review
-	of course).  This encourages us to merge your changes quicker,
-	while they are still "fresh".
-
-    o	Once your diffs are merged, you can obtain a new copy of glibc
-	containing your changes almost immediately.  Thus you do not
-	have to maintain local copies of your changes for any longer
-	than it takes to get them merged into the official source base.
-	This encourages you to send in changes quicker.
-
-    And the disadvantages:
-
-    o	The snapshot you get will be largely untested and of unknown quality.
-	It may fail to configure or compile.  It may have serious bugs.
-	You should always keep a copy of the last known working version
-	before updating to the current snapshot, or at least be able to
-	regenerate a working version if the latest snapshot is unusable
-	in your environment for some reason.
-
-	If a production version of glibc has a bug and a snapshot has the fix,
-	and you care about stability, you should put only the fix for that
-	particular problem into your production version.  Of course, if you
-	are eager to test glibc, you can use the snapshot versions in your
-	daily work, but users who have not been consulted about whether they
-	feel like testing glibc should generally have something which is at
-	least as bug free as the last released version.
-
-    o	Providing timely response to your questions, bug reports, and
-	submitted patches will require the glibc development team to allocate
-	time from an already thin time budget.  Please try to help us make
-	this time as productive as possible.  See the section below about
-	how to submit changes.
-
-
-WHO SHOULD TRY THE SNAPSHOTS
-----------------------------
-
-Remember, these are snapshots not tested versions.  So if you use
-these versions you should be able to
-
-    o	make sure your system stays usable
-
-    o	locate and hopefully fix problems
-
-    o	to port glibc to a new target yourself
-
-You should not use the snapshots if
-
-    o	your system is needed in a production environment which needs
-	stability
-
-    o	you expect us to fix your problems since you somehow depend on them.
-	You must be willing to fix the problems yourself, we don't want to
-	see "I have problems, fix this" messages.
-
-
-HOW TO GET THE SNAPSHOTS
-------------------------
-
-At the moment we provide a full snapshot weekly (every sunday), so
-that users getting a snapshot for the first time, or updating after
-a long period of not updating, can get the latest version in a single
-operation.  Along with the full snapshot, we will provide incremental
-diffs on a nearly daily basis (whenever code changes).  Each daily
-diff will be relative to the source tree after applying all previous
-daily diffs.  The daily diffs are for people who have relatively low
-bandwidth ftp or uucp connections.
-
-The files will be available via anonymous ftp from alpha.gnu.org, in
-directory /gnu/libc and on linux.kernel.org in /pub/software/libs/glibc.  The
-directories should look something like:
-
-	libc-970921.tar.gz
-	libc-970917-970922.diff.gz
-	libc-970922-970925.diff.gz
-	.
-	.
-	.
-
-Please note that the snapshots on alpha.gnu.org and on
-linux.kernel.org are not always in sync. Patches to some files might
-appear a day a diff earlier or later on alpha than on kernel.
-Use always alpha or always kernel but don't mix them.
-
-There are sometimes additionally test releases of the add-ons available in
-these directories.  If a new version of an add-on is available it is normally
-required for the corresponding snapshot so always pay attention for these.
-
-Note that we provide GNU gzip compressed files only.  You can ftp gzip
-from ftp.gnu.org in directory pub/gnu.
-
-In some cases the dates for diffs and snapshots do not match like in the
-example above.  The full release is for 970921 but the patch is for
-970917-970922.  This only means that nothing changed between 970917 and 970922
-and that you have to use this patch on top of the 970921 snapshot since the
-patch is made on 970922.
-
-Also, as the gcc developers did with their gcc snapshot system, even though we
-will make the snapshots available on a publically accessible ftp area, we ask
-that recipients not widely publicise their availability.  The motivation for
-this request is not to hoard them, but to avoid the situation where the
-general glibc user base naively attempts to use the snapshots, has trouble with
-them, complains publically, and the reputation of glibc declines because of a
-perception of instability or lack of quality control.
-
-
-GLIBC TEST SUITE
-----------------
-
-A test suite is distributed as an integral part of the snapshots.  A simple
-"make check" in your build directory is sufficient to run the tests.  glibc
-should pass all tests and if any fails, please report it.  A failure might not
-originate from a bug in glibc but also from bugs in the tools, e.g. with gcc
-2.7.2.x the math tests fail some of the tests because of compiler bugs.
-
-Note that the test suite is still in its infancy.  The tests themselves only
-cover a small portion of libc features, and where tests do exist for a feature
-they are not exhaustive.  New tests are welcome.
-
-
-GETTING HELP, GLIBC DISCUSSIONS, etc
-------------------------------------
-
-People who want to help with glibc and who test out snapshots
-regularly should get on the libc-alpha@sourceware.cygnus.com mailing
-list by sending an email to libc-alpha-subscribe@sourceware.cygnus.com.
-This list is meant (as the name suggests) for the discussion of test
-releases and also reports for them.  People who are on this list are
-welcome to post questions of general interest.
-
-People who are not only willing to test the snapshots but instead
-really want to help developing glibc should contact
-libc-hacker-subscribe@sourceware.cygnus.com.org to be put on the developers
-mailing list.  This list is really only meant for developers.  No
-questions about installation problems or other simple topics are
-wanted nor will they be answered.
-
-Do *not* send any questions about the snapshots or patches specific to the
-snapshots to bug-glibc@gnu.org.  Nobody there will have any idea what
-you are talking about and it will just cause confusion.
-
-
-BUG REPORTS
------------
-
-Send bug reports directly to Ulrich Drepper <drepper@gnu.org>.  Please
-do *not* use the glibcbug script for reporting bugs in the snapshots.
-glibcbug should only be used for problems with the official released versions.
-We don't like bug reports in the bug database because otherwise the impression
-of instability or lack of quality control of glibc as a whole might manifest
-in people's mind.
-
-Note that since no testing is done on the snapshots, and snapshots may even be
-made when glibc is in an inconsistent state, it may not be unusual for an
-occasional snapshot to have a very obvious bug, such as failure to compile on
-*any* machine.  It is likely that such bugs will be fixed by the next
-snapshot, so it really isn't necessary to report them unless they persist for
-a couple of days.
-
-Missing files should always be reported, since they usually mean there is a
-problem with the snapshot-generating process and we won't know about them
-unless someone tells us.
-
-Bugs which are non-obvious, such as failure to compile on only a specific
-machine, a new machine dependent or obscure bug (particularly one not detected
-by the testsuite), etc should be reported when you discover them, or have a
-suggested patch to fix them.
-
-
-FORMAT FOR PATCHES
-------------------
-
-If you have a fix for a bug, or an enhancement to submit, send your patch to
-Ulrich Drepper <drepper@gnu.org>.  Here are some simple guidelines for
-submitting patches:
-
-    o	Use "unified diffs" for patches.  A typical command for generating
-	context diffs is "diff -ru glibc-old glibc-patched".
-
-    o	Use the "minimalist approach" for patches.  That is, each patch
-	should address only one particular bug, new feature, etc.  Do not
-	save up many unrelated changes and submit them all in one big
-	patch, since in general, the larger the patch the more difficult
-	it is for us to decide if the patch is either correct or
-	desirable.  And if we find something about the patch that needs
-	to be corrected before it can be installed, we would have to reject
-	the entire patch, which might contain changes which otherwise would
-	be accepted if submitted separately.
-
-    o	Submit a sample ChangeLog entry with your patch.  See the existing
-	glibc ChangeLog for examples of what a ChangeLog entry should look
-	like.  The emacs command ^X4A will create a ChangeLog entry header
-	for you.
-
-
-BUILDING SNAPSHOTS
-------------------
-
-The `best' way to build glibc is to use an extra directory, e.g.:
-tar xzf libc-970921.tar.gz
-mkdir build-glibc
-cd build-glibc
-../libc-970921/configure ...
-
-In this way you can easily clean up (since `make clean' doesn't work at
-the moment) and rebuild glibc.
-
-
-NECESSARY TOOLS
----------------
-
-For the recommended versions of gcc, binutils, make, texinfo, gettext,
-autoconf and other tools which might be especially needed when using patches,
-please read the file INSTALL.
-
-
-HOW CAN YOU HELP
-----------------
-
-It helps already a lot if you just install glibc on your system and try to
-solve any problems.  You might want to look at the file `PROJECTS' and help
-with one of those projects, fix some bugs (see `BUGS' or the bug database),
-port to an unsupported platform, ...
-
-
-FURTHER DOCUMENTATION
----------------------
-
-A lot of questions are answered in the FAQ.  The files `INSTALL', `README' and
-`NOTES' contain the most important documentation.  Furthermore glibc has its
-own 700+ pages info documentation, ...
-
-
-
-And finally a word of caution: The libc is one of the most fundamental parts
-of your system - and these snapshots are untested and come without any
-guarantee or warranty.  You might be lucky and everything works or you might
-crash your system.  If you install a glibc snapshot as primary library, you
-should have a backup somewhere.
-
-On many systems it is also a problem to replace the libc while the system is
-running.  In the worst case on broken OSes some systems crash.  On better
-systems you can move the old libc aside but removing it will cause problems
-since there are still processes using this libc image and so you might have to
-check the filesystem to get rid of the libc data.  One good alternative (which
-is also safer) is to use a chroot'ed environment.
-
-Thanks for your help and support.
-
-Thanks to Fred Fish from Cygnus for the original version of this text
-(for GDB).

-   We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the

-   we used `long' when it's 64 bits where `long long' is expected, then the
-   compiler would warn about the formats not matching the argument types,
-   and the programmer changing them to shut up the compiler would break the
-   program's portability.
-
-   Here we assume what is presently the case in all the GCC configurations
-   we support: long long is always 64 bits, long is always word/address size,
-   and int is always 32 bits.  */

+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 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.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, 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 library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, 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 companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, 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 library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete 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 distribute a copy of this License along with the
+Library.
+
+  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 Library or any portion
+of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+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 Library, 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 Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you 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.
+
+  If distribution of 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 satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  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.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library 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.
+
+  9. 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 Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+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.
+
+  11. 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 Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library 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 Library.
+
+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.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library 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.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+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 Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+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
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. 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 LIBRARY 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
+LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  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 library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library 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
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; 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.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
