+Simple Test interface changes
+=============================
+Because the SimpleTest tool set is still evolving it is likely that tests
+written with earlier versions will fail with the newest ones. The most
+dramatic changes are in the alpha releases. Here is a list of possible
+problems and their fixes...
+
+No method getRelativeUrls() or getAbsoluteUrls()
+------------------------------------------------
+These methods were always a bit weird anyway, and
+the new parsing of the base tag makes them more so.
+They have been replaced with getUrls() instead. If
+you want the old functionality then simply chop
+off the current domain from getUrl().
+
+Method setWildcard() removed in mocks
+-------------------------------------
+Even setWildcard() has been removed in 1.0.1beta now.
+If you want to test explicitely for a '*' string, then
+simply pass in new IdenticalExpectation('*') instead.
+
+No method _getTest() on mocks
+-----------------------------
+This has finally been removed. It was a pretty esoteric
+flex point anyway. It was there to allow the mocks to
+work with other test tools, but no one does this.
+
+No method assertError(), assertNoErrors(), swallowErrors()
+----------------------------------------------------------
+These have been deprecated in 1.0.1beta in favour of
+expectError() and expectException(). assertNoErrors() is
+redundant if you use expectError() as failures are now reported
+immediately.
+
+No method TestCase::signal()
+----------------------------
+This has been deprecated in favour of triggering an error or
+throwing an exception. Deprecated as of 1.0.1beta.
+
+No method TestCase::sendMessage()
+---------------------------------
+This has been deprecated as of 1.0.1beta.
+
+Failure to connect now emits failures
+-------------------------------------
+It used to be that you would have to use the
+getTransferError() call on the web tester to see if
+there was a socket level error in a fetch. This check
+is now always carried out by the WebTestCase unless
+the fetch is prefaced with WebTestCase::ignoreErrors().
+The ignore directive only lasts for test case fetching
+action such as get() and click().
+
+No method SimpleTestOptions::ignore()
+-------------------------------------
+This is deprecated in version 1.0.1beta and has been moved
+to SimpleTest::ignore() as that is more readable. In
+addition, parent classes are also ignored automatically.
+If you are using PHP5 you can skip this directive simply
+by marking your test case as abstract.
+
+No method assertCopy()
+----------------------
+This is deprecated in 1.0.1 in favour of assertClone().
+The assertClone() method is slightly different in that
+the objects must be identical, but without being a
+reference. It is thus not a strict inversion of
+assertReference().
+
+Constructor wildcard override has no effect in mocks
+----------------------------------------------------
+As of 1.0.1beta this is now set with setWildcard() instead
+of in the constructor.
+
+No methods setStubBaseClass()/getStubBaseClass()
+------------------------------------------------
+As mocks are now used instead of stubs, these methods
+stopped working and are now removed as of the 1.0.1beta
+release. The mock objects may be freely used instead.
+
+No method addPartialMockCode()
+------------------------------
+The ability to insert arbitrary partial mock code
+has been removed. This was a low value feature
+causing needless complications. It was removed
+in the 1.0.1beta release.
+
+No method setMockBaseClass()
+----------------------------
+The ability to change the mock base class has been
+scheduled for removal and is deprecated since the
+1.0.1beta version. This was a rarely used feature
+except as a workaround for PHP5 limitations. As
+these limitations are being resolved it's hoped
+that the bundled mocks can be used directly.
+
+No class Stub
+-------------
+Server stubs are deprecated from 1.0.1 as the mocks now
+have exactly the same interface. Just use mock objects
+instead.
+
+No class SimpleTestOptions
+--------------------------
+This was replced by the shorter SimpleTest in 1.0.1beta1
+and is since deprecated.
+
+No file simple_test.php
+-----------------------
+This was renamed test_case.php in 1.0.1beta to more accurately
+reflect it's purpose. This file should never be directly
+included in test suites though, as it's part of the
+underlying mechanics and has a tendency to be refactored.
+
+No class WantedPatternExpectation
+---------------------------------
+This was deprecated in 1.0.1alpha in favour of the simpler
+name PatternExpectation.
+
+No class NoUnwantedPatternExpectation
+-------------------------------------
+This was deprecated in 1.0.1alpha in favour of the simpler
+name NoPatternExpectation.
+
+No method assertNoUnwantedPattern()
+-----------------------------------
+This has been renamed to assertNoPattern() in 1.0.1alpha and
+the old form is deprecated.
+
+No method assertWantedPattern()
+-------------------------------
+This has been renamed to assertPattern() in 1.0.1alpha and
+the old form is deprecated.
+
+No method assertExpectation()
+-----------------------------
+This was renamed as assert() in 1.0.1alpha and the old form
+has been deprecated.
+
+No class WildcardExpectation
+----------------------------
+This was a mostly internal class for the mock objects. It was
+renamed AnythingExpectation to bring it closer to JMock and
+NMock in version 1.0.1alpha.
+
+Missing UnitTestCase::assertErrorPattern()
+------------------------------------------
+This method is deprecated for version 1.0.1 onwards.
+This method has been subsumed by assertError() that can now
+take an expectation. Simply pass a PatternExpectation
+into assertError() to simulate the old behaviour.
+
+No HTML when matching page elements
+-----------------------------------
+This behaviour has been switched to using plain text as if it
+were seen by the user of the browser. This means that HTML tags
+are suppressed, entities are converted and whitespace is
+normalised. This should make it easier to match items in forms.
+Also images are replaced with their "alt" text so that they
+can be matched as well.
+
+No method SimpleRunner::_getTestCase()
+--------------------------------------
+This was made public as getTestCase() in 1.0RC2.
+
+No method restartSession()
+--------------------------
+This was renamed to restart() in the WebTestCase, SimpleBrowser
+and the underlying SimpleUserAgent in 1.0RC2. Because it was
+undocumented anyway, no attempt was made at backward
+compatibility.
+
+My custom test case ignored by tally()
+--------------------------------------
+The _assertTrue method has had it's signature changed due to a bug
+in the PHP 5.0.1 release. You must now use getTest() from within
+that method to get the test case. Mock compatibility with other
+unit testers is now deprecated as of 1.0.1alpha as PEAR::PHPUnit2
+should soon have mock support of it's own.
+
+Broken code extending SimpleRunner
+----------------------------------
+This was replaced with SimpleScorer so that I could use the runner
+name in another class. This happened in RC1 development and there
+is no easy backward compatibility fix. The solution is simply to
+extend SimpleScorer instead.
+
+Missing method getBaseCookieValue()
+-----------------------------------
+This was renamed getCurrentCookieValue() in RC1.
+
+Missing files from the SimpleTest suite
+---------------------------------------
+Versions of SimpleTest prior to Beta6 required a SIMPLE_TEST constant
+to point at the SimpleTest folder location before any of the toolset
+was loaded. This is no longer documented as it is now unnecessary
+for later versions. If you are using an earlier version you may
+need this constant. Consult the documentation that was bundled with
+the release that you are using or upgrade to Beta6 or later.
+
+No method SimpleBrowser::getCurrentUrl()
+--------------------------------------
+This is replaced with the more versatile showRequest() for
+debugging. It only existed in this context for version Beta5.
+Later versions will have SimpleBrowser::getHistory() for tracking
+paths through pages. It is renamed as getUrl() since 1.0RC1.
+
+No method Stub::setStubBaseClass()
+----------------------------------
+This method has finally been removed in 1.0RC1. Use
+SimpleTestOptions::setStubBaseClass() instead.
+
+No class CommandLineReporter
+----------------------------
+This was renamed to TextReporter in Beta3 and the deprecated version
+was removed in 1.0RC1.
+
+No method requireReturn()
+-------------------------
+This was deprecated in Beta3 and is now removed.
+
+No method expectCookie()
+------------------------
+This method was abruptly removed in Beta4 so as to simplify the internals
+until another mechanism can replace it. As a workaround it is necessary
+to assert that the cookie has changed by setting it before the page
+fetch and then assert the desired value.
+
+No method clickSubmitByFormId()
+-------------------------------
+This method had an incorrect name as no button was involved. It was
+renamed to submitByFormId() in Beta4 and the old version deprecated.
+Now removed.
+
+No method paintStart() or paintEnd()
+------------------------------------
+You should only get this error if you have subclassed the lower level
+reporting and test runner machinery. These methods have been broken
+down into events for test methods, events for test cases and events
+for group tests. The new methods are...
+
+paintStart() --> paintMethodStart(), paintCaseStart(), paintGroupStart()
+paintEnd() --> paintMethodEnd(), paintCaseEnd(), paintGroupEnd()
+
+This change was made in Beta3, ironically to make it easier to subclass
+the inner machinery. Simply duplicating the code you had in the previous
+methods should provide a temporary fix.
+
+No class TestDisplay
+--------------------
+This has been folded into SimpleReporter in Beta3 and is now deprecated.
+It was removed in RC1.
+
+No method WebTestCase::fetch()
+------------------------------
+This was renamed get() in Alpha8. It is removed in Beta3.
+
+No method submit()
+------------------
+This has been renamed clickSubmit() in Beta1. The old method was
+removed in Beta2.
+
+No method clearHistory()
+------------------------
+This method is deprecated in Beta2 and removed in RC1.
+
+No method getCallCount()
+------------------------
+This method has been deprecated since Beta1 and has now been
+removed. There are now more ways to set expectations on counts
+and so this method should be unecessery. Removed in RC1.
+
+Cannot find file *
+------------------
+The following public name changes have occoured...
+
+simple_html_test.php --> reporter.php
+simple_mock.php --> mock_objects.php
+simple_unit.php --> unit_tester.php
+simple_web.php --> web_tester.php
+
+The old names were deprecated in Alpha8 and removed in Beta1.
+
+No method attachObserver()
+--------------------------
+Prior to the Alpha8 release the old internal observer pattern was
+gutted and replaced with a visitor. This is to trade flexibility of
+test case expansion against the ease of writing user interfaces.
+
+Code such as...
+
+$test = &new MyTestCase();
+$test->attachObserver(new TestHtmlDisplay());
+$test->run();
+
+...should be rewritten as...
+
+$test = &new MyTestCase();
+$test->run(new HtmlReporter());
+
+If you previously attached multiple observers then the workaround
+is to run the tests twice, once with each, until they can be combined.
+For one observer the old method is simulated in Alpha 8, but is
+removed in Beta1.
+
+No class TestHtmlDisplay
+------------------------
+This class has been renamed to HtmlReporter in Alpha8. It is supported,
+but deprecated in Beta1 and removed in Beta2. If you have subclassed
+the display for your own design, then you will have to extend this
+class (HtmlReporter) instead.
+
+If you have accessed the event queue by overriding the notify() method
+then I am afraid you are in big trouble :(. The reporter is now
+carried around the test suite by the runner classes and the methods
+called directly. In the unlikely event that this is a problem and
+you don't want to upgrade the test tool then simplest is to write your
+own runner class and invoke the tests with...
+
+$test->accept(new MyRunner(new MyReporter()));
+
+...rather than the run method. This should be easier to extend
+anyway and gives much more control. Even this method is overhauled
+in Beta3 where the runner class can be set within the test case. Really
+the best thing to do is to upgrade to this version as whatever you were
+trying to achieve before should now be very much easier.
+
+Missing set options method
+--------------------------
+All test suite options are now in one class called SimpleTestOptions.
+This means that options are set differently...
+
+GroupTest::ignore() --> SimpleTestOptions::ignore()
+Mock::setMockBaseClass() --> SimpleTestOptions::setMockBaseClass()
+
+These changed in Alpha8 and the old versions are now removed in RC1.
+
+No method setExpected*()
+------------------------
+The mock expectations changed their names in Alpha4 and the old names
+ceased to be supported in Alpha8. The changes are...
+
+setExpectedArguments() --> expectArguments()
+setExpectedArgumentsSequence() --> expectArgumentsAt()
+setExpectedCallCount() --> expectCallCount()
+setMaximumCallCount() --> expectMaximumCallCount()
+
+The parameters remained the same.

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  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 Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    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 Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+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 other code 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.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  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, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser 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 combine 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) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) 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.
+
+    d) 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.
+
+    e) 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 materials to be 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 with
+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 Lesser 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
+
+           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 Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 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
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  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.
+
+  <signature of Ty Coon>, 1 April 1990

+
+That's all there is to it!

+SimpleTest
+==========
+You probably got this package from...
+http://simpletest.sourceforge.net/projects/simpletest/
+
+If there is no licence agreement with this package please download
+a version from the location above. You must read and accept that
+licence to use this software. The file is titled simply LICENSE.
+
+What is it? It's a framework for unit testing, web site testing and
+mock objects for PHP 4.2.0+ (and PHP 5.0 to 5.3 without E_STRICT).
+
+If you have used JUnit, you will find this PHP unit testing version very
+similar. Also included is a mock objects and server stubs generator.
+The stubs can have return values set for different arguments, can have
+sequences set also by arguments and can return items by reference.
+The mocks inherit all of this functionality and can also have
+expectations set, again in sequences and for different arguments.
+
+A web tester similar in concept to JWebUnit is also included. There is no
+JavaScript or tables support, but forms, authentication, cookies and
+frames are handled.
+
+You can see a release schedule at http://www.lastcraft.com/overview.php
+which is also copied to the documentation folder with this release.
+A full PHPDocumenter API documentation exists at
+http://simpletest.sourceforge.net/.
+
+The user interface is minimal
+in the extreme, but a lot of information flows from the test suite.
+After version 1.0 we will release a better web UI, but we are leaving XUL
+and GTk versions to volunteers as everybody has their own opinion
+on a good GUI, and we don't want to discourage development by shipping
+one with the toolkit. YOucan download an Eclipse plug-in separately.
+
+You are looking at a second full release. The unit tests for SimpleTest
+itself can be run here...
+
+simpletest/test/unit_tests.php
+
+And tests involving live network connections as well are here...
+
+simpletest/test/all_tests.php
+
+The full tests will typically overrun the 8Mb limit often allowed
+to a PHP process. A workaround is to run the tests on the command
+with a custom php.ini file if you do not have access to your server
+version.
+
+You will have to edit the all_tests.php file if you are accesssing
+the internet through a proxy server. See the comments in all_tests.php
+for instructions.
+
+The full tests read some test data from the LastCraft site. If the site
+is down or has been modified for a later version then you will get
+spurious errors. A unit_tests.php failure on the other hand would be
+very serious. As far as we know we haven't yet managed to check in any
+unit test failures, so please correct us if you find one.
+
+Even if all of the tests run please verify that your existing test suites
+also function as expected. If they don't see the file...
+
+HELP_MY_TESTS_DONT_WORK_ANYMORE
+
+This contains information on interface changes. It also points out
+deprecated interfaces, so you should read this even if all of
+your current tests appear to run.
+
+There is a documentation folder which contains the core reference information
+in English and French, although this information is fairly basic.
+You can find a tutorial on...
+
+http://www.lastcraft.com/first_test_tutorial.php
+
+...to get you started and this material will eventually become included
+with the project documentation. A French translation exists at...
+
+http://www.onpk.net/index.php/2005/01/12/254-tutoriel-simpletest-decouvrir-les-tests-unitaires.
+
+If you download and use, and possibly even extend this tool, please let us
+know. Any feedback, even bad, is always welcome and we will work to get
+your suggestions into the next release. Ideally please send your
+comments to...
+
+simpletest-support@lists.sourceforge.net
+
+...so that others can read them too. We usually try to respond within 48
+hours.
+
+There is no change log except at Sourceforge. You can visit the
+release notes to see the completed TODO list after each cycle and also the
+status of any bugs, but if the bug is recent then it will be fixed in SVN only.
+The SVN check-ins always have all the tests passing and so SVN snapshots should
+be pretty usable, although the code may not look so good internally.
+
+Oh, yes. It is called "Simple" because it should be simple to
+use. We intend to add a complete set of tools for a test first
+and "test as you code" type of development. "Simple" does not
+mean "Lite" in this context.
+
+Thanks to everyone who has sent comments and offered suggestions. They
+really are invaluable, but sadly you are too many to mention in full.
+Thanks to all on the advanced PHP forum on SitePoint, especially Harry
+Feucks. Early adopters are always an inspiration.
+
+Marcus Baker, Jason Sweat, Travis Swicegood, Perrick Penet and Edward Z. Yang.
