  Log:
  Adding Expat 1.0.2 to the Apache repository. Apache elects to use the MPL
  license, per the instructions in expat.html. This version of Expat 1.0.2
  has been modified to contain only the tokenizer and parser, and the
  Makefile has been adjusted to use Apache conventions (Makefile.tmpl).
  See http://www.jclark.com/xml/expat.html for more information on Expat.

      </UL>
  
  </UL>
  <B>3. Distribution Obligations.</B>
  <UL>
  
      <B>3.1. Application of License.</B>
  
      <BR>The Modifications which You create or to which You contribute are
      governed by the terms of this License, including without limitation
      Section <B>2.2</B>.  The Source Code version of Covered Code may be
      distributed only under the terms of this License or a future version of
      this License released under Section <B>6.1</B>, and You must include a
      copy of this License with every copy of the Source Code You
      distribute. You may not offer or impose any terms on any Source Code
      version that alters or restricts the applicable version of this License
      or the recipients' rights hereunder. However, You may include an
      additional document offering the additional rights described in Section
      <B>3.5</B>.
  
      <P><B>3.2. Availability of Source Code.</B>
  
      <BR>Any Modification which You create or to which You contribute must be
      made available in Source Code form under the terms of this License either
      on the same media as an Executable version or via an accepted Electronic
      Distribution Mechanism to anyone to whom you made an Executable version
      available; and if made available via Electronic Distribution Mechanism,
      must remain available for at least twelve (12) months after the date it
      initially became available, or at least six (6) months after a subsequent
      version of that particular Modification has been made available to such
      recipients. You are responsible for ensuring that the Source Code version
      remains available even if the Electronic Distribution Mechanism is
      maintained by a third party.
  
      <P><B>3.3. Description of Modifications.</B>
  
      <BR>You must cause all Covered Code to which you contribute to contain a
      file documenting the changes You made to create that Covered Code and the
      date of any change. You must include a prominent statement that the
      Modification is derived, directly or indirectly, from Original Code
      provided by the Initial Developer and including the name of the Initial
      Developer in (a) the Source Code, and (b) in any notice in an Executable
      version or related documentation in which You describe the origin or
      ownership of the Covered Code.
  
      <P><B>3.4. Intellectual Property Matters</B>
      <UL>
  
  	<P><B>(a) Third Party Claims</B>. 
  
  	<BR>If You have knowledge that a party claims an intellectual
  	property right in particular functionality or code (or its
  	utilization under this License), you must include a text file with
  	the source code distribution titled ``LEGAL'' which describes the
  	claim and the party making the claim in sufficient detail that a
  	recipient will know whom to contact. If you obtain such knowledge
  	after You make Your Modification available as described in Section
  	<B>3.2</B>, You shall promptly modify the LEGAL file in all copies
  	You make available thereafter and shall take other steps (such as
  	notifying appropriate mailing lists or newsgroups) reasonably
  	calculated to inform those who received the Covered Code that new
  	knowledge has been obtained.
  
  	<P><B>(b) Contributor APIs</B>. 
  
  	<BR>If Your Modification is an application programming interface and
  	You own or control patents which are reasonably necessary to
  	implement that API, you must also include this information in the
  	LEGAL file.
  
      </UL>
  
      <P><B>3.5. Required Notices.</B>
  
      <BR>You must duplicate the notice in <B>Exhibit A</B> in each file of the
      Source Code, and this License in any documentation for the Source Code,
      where You describe recipients' rights relating to Covered Code. If You
      created one or more Modification(s), You may add your name as a
      Contributor to the notice described in <B>Exhibit A</B>. If it is not
      possible to put such notice in a particular Source Code file due to its
      structure, then you must include such notice in a location (such as a
      relevant directory file) where a user would be likely to look for such a
      notice.  You may choose to offer, and to charge a fee for, warranty,
      support, indemnity or liability obligations to one or more recipients of
      Covered Code. However, You may do so only on Your own behalf, and not on
      behalf of the Initial Developer or any Contributor.  You must make it
      absolutely clear than any such warranty, support, indemnity or liability
      obligation is offered by You alone, and You hereby agree to indemnify the
      Initial Developer and every Contributor for any liability incurred by the
      Initial Developer or such Contributor as a result of warranty, support,
      indemnity or liability terms You offer.
  
      <P><B>3.6. Distribution of Executable Versions.</B>
  
      <BR>You may distribute Covered Code in Executable form only if the
      requirements of Section <B>3.1-3.5</B> have been met for that Covered
      Code, and if You include a notice stating that the Source Code version of
      the Covered Code is available under the terms of this License, including
      a description of how and where You have fulfilled the obligations of
      Section <B>3.2</B>.  The notice must be conspicuously included in any
      notice in an Executable version, related documentation or collateral in
      which You describe recipients' rights relating to the Covered Code. You
      may distribute the Executable version of Covered Code under a license of
      Your choice, which may contain terms different from this License,
      provided that You are in compliance with the terms of this License and
      that the license for the Executable version does not attempt to limit or
      alter the recipient's rights in the Source Code version from the rights
      set forth in this License. If You distribute the Executable version under
      a different license You must make it absolutely clear that any terms
      which differ from this License are offered by You alone, not by the
      Initial Developer or any Contributor. You hereby agree to indemnify the
      Initial Developer and every Contributor for any liability incurred by the
      Initial Developer or such Contributor as a result of any such terms You
      offer.
  
      <P><B>3.7. Larger Works.</B>
  
      <BR>You may create a Larger Work by combining Covered Code with other
      code not governed by the terms of this License and distribute the Larger
      Work as a single product. In such a case, You must make sure the
      requirements of this License are fulfilled for the Covered Code.
  
  </UL>
  <B>4. Inability to Comply Due to Statute or Regulation.</B>
  <UL>
  
      <P>If it is impossible for You to comply with any of the terms of this
      License with respect to some or all of the Covered Code due to statute or
      regulation then You must: (a) comply with the terms of this License to
      the maximum extent possible; and (b) describe the limitations and the
      code they affect. Such description must be included in the LEGAL file
      described in Section <B>3.4</B> and must be included with all
      distributions of the Source Code. Except to the extent prohibited by
      statute or regulation, such description must be sufficiently detailed for
      a recipient of ordinary skill
      to be able to understand it.
  
  </UL>
  <B>5. Application of this License.</B>
  <UL>
  
      This License applies to code to which the Initial Developer has attached
      the notice in <B>Exhibit A</B>, and to related Covered Code.
  
  </UL>
  <B>6. Versions of the License.</B>
  <UL>
  
      <B>6.1. New Versions</B>. 
  
      <BR>Netscape Communications Corporation (``Netscape'') may publish
      revised and/or new versions of the License from time to time.  Each
      version will be given a distinguishing version number.
  
      <P><B>6.2. Effect of New Versions</B>. 
  
      <BR>Once Covered Code has been published under a particular version of
      the License, You may always continue to use it under the terms of that
      version. You may also choose to use such Covered Code under the terms of
      any subsequent version of the License published by Netscape. No one other
      than Netscape has the right to modify the terms applicable to Covered
      Code created under this License.
  
      <P><B>6.3. Derivative Works</B>. 
  
      <BR>If you create or use a modified version of this License (which you
      may only do in order to apply it to code which is not already Covered
      Code governed by this License), you must (a) rename Your license so that
      the phrases ``Mozilla'', ``MOZILLAPL'', ``MOZPL'', ``Netscape'', ``NPL''
      or any confusingly similar phrase do not appear anywhere in your license
      and (b) otherwise make it clear that your version of the license contains
      terms which differ from the Mozilla Public License and Netscape Public
      License. (Filling in the name of the Initial Developer, Original Code or
      Contributor in the notice described in <B>Exhibit A</B> shall not of
      themselves be deemed to be modifications of this License.)
  
  </UL>
  <B>7. DISCLAIMER OF WARRANTY.</B>
  <UL>
  
      COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN ``AS IS'' BASIS,
      WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
      WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF DEFECTS,
      MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE
      RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE IS WITH
      YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE
      INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY
      NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY
      CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED CODE
      IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
  
  </UL>
  <B>8. TERMINATION.</B>
  <UL>
  
      This License and the rights granted hereunder will terminate
      automatically if You fail to comply with terms herein and fail to cure
      such breach within 30 days of becoming aware of the breach. All
      sublicenses to the Covered Code which are properly granted shall survive
      any termination of this License.  Provisions which, by their nature, must
      remain in effect beyond the termination of this License shall survive.
  
  </UL>
  <B>9. LIMITATION OF LIABILITY.</B>
  <UL>
  
      UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING
      NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE INITIAL DEVELOPER, ANY
      OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE, OR ANY SUPPLIER OF
      ANY OF SUCH PARTIES, BE LIABLE TO YOU OR ANY OTHER PERSON FOR ANY
      INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER
      INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK
      STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
      COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED
      OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL
      NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH
      PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH
      LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION
      OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THAT EXCLUSION AND LIMITATION
      MAY NOT APPLY TO YOU.
  
  </UL>
  <B>10. U.S. GOVERNMENT END USERS.</B>
  <UL>
  
      The Covered Code is a ``commercial item,'' as that term is defined in 48
      C.F.R. 2.101 (Oct. 1995), consisting of ``commercial computer software''
      and ``commercial computer software documentation,'' as such terms are
      used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212
      and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all
      U.S. Government End Users acquire Covered Code with only those rights set
      forth herein.
  
  </UL>
  <B>11. MISCELLANEOUS.</B>
  <UL>
  
      This License represents the complete agreement concerning subject matter
      hereof. If any provision of this License is held to be unenforceable,
      such provision shall be reformed only to the extent necessary to make it
      enforceable. This License shall be governed by California law provisions
      (except to the extent applicable law, if any, provides otherwise),
      excluding its conflict-of-law provisions. With respect to disputes in
      which at least one party is a citizen of, or an entity chartered or
      registered to do business in, the United States of America: (a) unless
      otherwise agreed in writing, all disputes relating to this License
      (excepting any dispute relating to intellectual property rights) shall be
      subject to final and binding arbitration, with the losing party paying
      all costs of arbitration; (b) any arbitration relating to this Agreement
      shall be held in Santa Clara County, California, under the auspices of
      JAMS/EndDispute; and (c) any litigation relating to this Agreement shall
      be subject to the jurisdiction of the Federal Courts of the Northern
      District of California, with venue lying in Santa Clara County,
      California, with the losing party responsible for costs, including
      without limitation, court costs and reasonable attorneys fees and
      expenses.  The application of the United Nations Convention on Contracts
      for the International Sale of Goods is expressly excluded. Any law or
      regulation which provides that the language of a contract shall be
      construed against the drafter shall not apply to this License.
  
  </UL>
  <B>12. RESPONSIBILITY FOR CLAIMS.</B>
  <UL>
  
      Except in cases where another Contributor has failed to comply with
      Section <B>3.4</B>, You are responsible for damages arising, directly or
      indirectly, out of Your utilization of rights under this License, based
      on the number of copies of Covered Code you made available, the revenues
      you received from utilizing such rights, and other relevant factors. You
      agree to work with affected parties to distribute responsibility on an
      equitable basis.

  <P>Expat is an <A
  HREF="http://www.w3.org/TR/1998/REC-xml-19980210">XML 1.0</A> parser
  written in C. It aims to be fully conforming.  It is currently not a
  validating XML processor.  Expat can be downloaded from <A href =
  "ftp://ftp.jclark.com/pub/xml/expat.zip"
  >ftp://ftp.jclark.com/pub/xml/expat.zip</A>.  This is a production
  version.</P>
  
  <P>The directory <SAMP>xmltok</SAMP> contains a low-level library for
  tokenizing XML.  The interface is documented in
  <SAMP>xmltok/xmltok.h</SAMP>.</P>
  
  <P>The directory <SAMP>xmlparse</SAMP> contains an XML parser library
  which is built on top of the <SAMP>xmltok</SAMP> library.  The
  interface is documented in <SAMP>xmlparse/xmlparse.h</SAMP>.  The
  directory <SAMP>sample</SAMP> contains a simple example program using
  this interface; <SAMP>sample/build.bat</SAMP> is a batch file to build
  the example using Visual C++.</P>
  
  <P>The directory <SAMP>xmlwf</SAMP> contains the <SAMP>xmlwf</SAMP>
  application, which uses the <SAMP>xmlparse</SAMP> library. The
  arguments to <SAMP>xmlwf</SAMP> are one or more files which are each
  to be checked for well-formedness. An option <SAMP>-d
  <VAR>dir</VAR></SAMP> can be specified; for each well-formed input
  file the corresponding <A
  href="http://www.jclark.com/xml/canonxml.html">canonical XML</A> will
  be written to <SAMP>dir/<VAR>f</VAR></SAMP>, where
  <SAMP><VAR>f</VAR></SAMP> is the filename (without any path) of the
  input file.  A <CODE>-x</CODE> option will cause references to
  external general entities to be processed.</P>
  
  <P>The <SAMP>bin</SAMP> directory contains Win32 executables.  The
  <SAMP>lib</SAMP> directory contains Win32 import libraries.</P>

  /* This structure is filled in by the XML_UnknownEncodingHandler
  to provide information to the parser about encodings that are unknown

  The map[b] member gives information about byte sequences
  whose first byte is b.
  If map[b] is c where c is >= 0, then b by itself encodes the Unicode scalar value c.
  If map[b] is -1, then the byte sequence is malformed.
  If map[b] is -n, where n >= 2, then b is the first byte of an n-byte
  sequence that encodes a single Unicode scalar value.
  The data member will be passed as the first argument to the convert function.
  The convert function is used to convert multibyte sequences;
  s will point to a n-byte sequence where map[(unsigned char)*s] == -n.
  The convert function must return the Unicode scalar value
  represented by this byte sequence or -1 if the byte sequence is malformed.
  The convert function may be null if the encoding is a single-byte encoding,
  that is if map[b] >= -1 for all bytes b.
  When the parser is finished with the encoding, then if release is not null,
  it will call release passing it the data member;
  once release has been called, the convert function will not be called again.
  
  Expat places certain restrictions on the encodings that are supported
  using this mechanism.
  
  1. Every ASCII character that can appear in a well-formed XML document,
  other than the characters
  
    $@\^`{}~
  
  must be represented by a single byte, and that byte must be the
  same byte that represents that character in ASCII.
  
  2. No character may require more than 4 bytes to encode.
  
  3. All characters encoded must have Unicode scalar values <= 0xFFFF,
  (ie characters that would be encoded by surrogates in UTF-16
  are  not allowed).  Note that this restriction doesn't apply to
  the built-in support for UTF-8 and UTF-16.
  
  4. No Unicode character may be encoded by more than one distinct sequence
  of bytes. */
