+Revision history for Bio-ASN1-Entrezgene
+
+1.70      2013-09-14 14:39:54 America/Chicago
+  * Bio::ASN1::EntrezGene is now able to parse EntrezGene-set in which case
+    next_seq() will return the next set of sequences with each sequence as
+    an element in the array ref instead of an array ref with a single element.
+
+version 1.10: Important update if you see segmentation fault when running the
+              parser - so far I only saw it happen on Perl 5.8 (Perl 5.10 is 
+              fine) due to an exceedingly long (and invalid) URL in one 
+              Arabidopsis entry. It's due to Perl regex engine core dumps when
+              matching the long string exhausted the stack. I changed the 
+              particular regex in EntrezGene.pm and Sequence.pm to solve the 
+              issue. The overall parsing runs 2-3% faster after the change.
+
 version 1.09: Added parser/indexer for NCBI's ASN.1-formatted
                 sequence files (like Genbank records).
               Updated test, example scripts and documentation

+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The license agreements of most software companies try to keep users
+at the mercy of those companies.  By contrast, our General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, that you receive source code or can get it if you want it,
+that you can change the software or use pieces of it in new free
+programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of a such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must tell them their rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License.  The
+"Program", below, refers to any such program or work, and a "work based
+on the Program" means either the Program or any work containing the
+Program or a portion of it, either verbatim or with modifications.  Each
+licensee is addressed as "you".
+
+  1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program.  You may charge a fee for the physical act of
+transferring a copy.
+
+  2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+    a) cause the modified files to carry prominent notices stating that
+    you changed the files and the date of any change; and
+
+    b) cause the whole of any work that you distribute or publish, that
+    in whole or in part contains the Program or any part thereof, either
+    with or without modifications, to be licensed at no charge to all
+    third parties under the terms of this General Public License (except
+    that you may choose to grant warranty protection to some or all
+    third parties, at your option).
+
+    c) If the modified program normally reads commands interactively when
+    run, you must cause it, when started running for such interactive use
+    in the simplest and most usual way, to print or display an
+    announcement including an appropriate copyright notice and a notice
+    that there is no warranty (or else, saying that you provide a
+    warranty) and that users may redistribute the program under these
+    conditions, and telling the user how to view a copy of this General
+    Public License.
+
+    d) 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.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+
+  3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 1 and 2 above provided that you also do one of the following:
+
+    a) accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    b) accompany it with a written offer, valid for at least three
+    years, to give any third party free (except for a nominal charge
+    for the cost of distribution) a complete machine-readable copy of the
+    corresponding source code, to be distributed under the terms of
+    Paragraphs 1 and 2 above; or,
+
+    c) accompany it with the information you received as to where the
+    corresponding source code may be obtained.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it.  For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+  4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License.  However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+  5. By copying, distributing or modifying the Program (or any work based
+on the Program) you indicate your acceptance of this license to do so,
+and all its terms and conditions.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these
+terms and conditions.  You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein.
+
+  7. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of the license which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+  8. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+        Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to humanity, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+  To do so, attach the following notices to the program.  It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 1, or (at your option)
+    any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA  02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19xx name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License.  Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  program `Gnomovision' (a program to direct compilers to make passes
+  at assemblers) written by James Hacker.

+
+This is free software, licensed under:
+
+  The Artistic License 1.0
+
+The Artistic License
+
+Preamble
+
+The intent of this document is to state the conditions under which a Package
+may be copied, such that the Copyright Holder maintains some semblance of
+artistic control over the development of the package, while giving the users of
+the package the right to use and distribute the Package in a more-or-less
+customary fashion, plus the right to make reasonable modifications.
+
+Definitions:
+
+  - "Package" refers to the collection of files distributed by the Copyright
+    Holder, and derivatives of that collection of files created through
+    textual modification. 
+  - "Standard Version" refers to such a Package if it has not been modified,
+    or has been modified in accordance with the wishes of the Copyright
+    Holder. 
+  - "Copyright Holder" is whoever is named in the copyright or copyrights for
+    the package. 
+  - "You" is you, if you're thinking about copying or distributing this Package.
+  - "Reasonable copying fee" is whatever you can justify on the basis of media
+    cost, duplication charges, time of people involved, and so on. (You will
+    not be required to justify it to the Copyright Holder, but only to the
+    computing community at large as a market that must bear the fee.) 
+  - "Freely Available" means that no fee is charged for the item itself, though
+    there may be fees involved in handling the item. It also means that
+    recipients of the item may redistribute it under the same conditions they
+    received it. 
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you
+duplicate all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications derived
+from the Public Domain or from the Copyright Holder. A Package modified in such
+a way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided that
+you insert a prominent notice in each changed file stating how and when you
+changed that file, and provided that you do at least ONE of the following:
+
+  a) place your modifications in the Public Domain or otherwise make them
+     Freely Available, such as by posting said modifications to Usenet or an
+     equivalent medium, or placing the modifications on a major archive site
+     such as ftp.uu.net, or by allowing the Copyright Holder to include your
+     modifications in the Standard Version of the Package.
+
+  b) use the modified Package only within your corporation or organization.
+
+  c) rename any non-standard executables so the names do not conflict with
+     standard executables, which must also be provided, and provide a separate
+     manual page for each non-standard executable that clearly documents how it
+     differs from the Standard Version.
+
+  d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or executable
+form, provided that you do at least ONE of the following:
+
+  a) distribute a Standard Version of the executables and library files,
+     together with instructions (in the manual page or equivalent) on where to
+     get the Standard Version.
+
+  b) accompany the distribution with the machine-readable source of the Package
+     with your modifications.
+
+  c) accompany any non-standard executables with their corresponding Standard
+     Version executables, giving the non-standard executables non-standard
+     names, and clearly documenting the differences in manual pages (or
+     equivalent), together with instructions on where to get the Standard
+     Version.
+
+  d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this
+Package.  You may charge any fee you choose for support of this Package. You
+may not charge a fee for this Package itself. However, you may distribute this
+Package in aggregate with other (possibly commercial) programs as part of a
+larger (possibly commercial) software distribution provided that you do not
+advertise this Package as a product of your own.
+
+6. The scripts and library files supplied as input to or produced as output
+from the programs of this Package do not automatically fall under the copyright
+of this Package, but belong to whomever generated them, and may be sold
+commercially, and may be aggregated with this Package.
+
+7. C or perl subroutines supplied by you and linked into this Package shall not
+be considered part of this Package.
+
+8. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.
+
+9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
+WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
+MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

-This is the README file for Bio::ASN1::EntrezGene package, which
-includes:
-1. XML parser-like parser for the ASN.1-formatted NCBI Entrez Gene files.
-2. Indexer for Entrez Gene files.
-3. XML parser-like parser for the ASN.1-formatted NCBI Sequence files.
-4. Indexer for Sequence files.
-
-These modules have quite high performance and error reporting capabilities.
-Additionally, one could dump the data structure generated from extracted
-NCBI object records into XML extremely easily using XML::Simple's XMLout().

-INSTALLATION
-
-Bio::ASN1::EntrezGene package can be installed & tested as follows:
-
-perl Makefile.PL
-make
-make test
-make install
-
-DOCUMENTATION
-
-For documentation, among many other things, please refer to the POD (
-plain old documentation) inside the module.
-
-It is highly recommended that you check the example scripts out (under
-the examples directory)!

-Please note that Bio::ASN1::EntrezGene package version 1.091 is exactly the
-same as version 1.09 (the only difference being that this file only exists
-in version 1.091).  The reason for releasing a version 1.091 is that CPAN
-indexing of Bio::ASN1::EntrezGene version 1.09 had some problem that is not

+Bio-ASN1-Entrezgene
+===================
+
+This distribution includes:
+1. XML parser-like parser for the ASN.1-formatted NCBI Entrez Gene files.
+2. Indexer for Entrez Gene files.
+3. XML parser-like parser for the ASN.1-formatted NCBI Sequence files.
+4. Indexer for Sequence files.
+
+These modules have quite high performance and error reporting capabilities.
+Additionally, one could dump the data structure generated from extracted
+NCBI object records into XML extremely easily using XML::Simple's XMLout().

-=head1 DESCRIPTION
-
-Bio::ASN1::EntrezGene is a regular expression-based Perl Parser for NCBI Entrez
-Gene genome databases (L<http://www.ncbi.nih.gov/entrez/query.fcgi?db=gene>).  It
-parses an ASN.1-formatted Entrez Gene record and returns a data structure that
-contains all data items from the gene record.
-
-The parser will report error & line number if input data does not conform to the
-NCBI Entrez Gene genome annotation file format.
-
-Note that it is possible to provide reading of all NCBI's ASN.1-formatted
-files through simple variations of the Entrez Gene parser (I need more
-investigation to be sure, but at least the sequence parser is a very simple
-variation on Entrez Gene parser and works well).
-
-It took the parser version 1.0 11 minutes to parse the human genome Entrez Gene
-file on one 2.4 GHz Intel Xeon processor.  The addition of validation and error
-reporting in 1.03 and handling of new Entrez Gene format slowed the parser down
-about 40%.
-
-Since V1.07, this package also included an indexer that runs pretty fast (it 
-takes 21 seconds for the indexer to index the human genome on the same 
-processor).  Therefore the combination of the modules would allow user to 
-retrieve and parse arbitrary records.
-
-=head1 SEE ALSO
-
-The parse_entrez_gene_example.pl script included in this package (please 
-see the Bio-ASN1-EntrezGene-x.xx/examples directory) is a very
-important and near-complete demo on using this module to extract all data
-items from Entrez Gene records.  Do check it out because in fact, this 
-script took me about 3-4 times more time to make for my project than the 
-parser V1.0 itself. Note that the example script was edited to leave
-out stuff specific to my internal project.
-
-For details on various parsers I generated for Entrez Gene, example scripts that 
-uses/benchmarks the modules, please see L<http://sourceforge.net/projects/egparser/>.

+
+=head1 DESCRIPTION
+
+Bio::ASN1::EntrezGene is a regular expression-based Perl Parser for NCBI Entrez
+Gene genome databases (L<http://www.ncbi.nih.gov/entrez/query.fcgi?db=gene>).  It
+parses an ASN.1-formatted Entrez Gene record and returns a data structure that
+contains all data items from the gene record.
+
+The parser will report error & line number if input data does not conform to the
+NCBI Entrez Gene genome annotation file format.
+
+Note that it is possible to provide reading of all NCBI's ASN.1-formatted
+files through simple variations of the Entrez Gene parser (I need more
+investigation to be sure, but at least the sequence parser is a very simple
+variation on Entrez Gene parser and works well).
+
+It took the parser version 1.0 11 minutes to parse the human genome Entrez Gene
+file on one 2.4 GHz Intel Xeon processor.  The addition of validation and error
+reporting in 1.03 and handling of new Entrez Gene format slowed the parser down
+about 40%.
+
+Since V1.07, this package also included an indexer that runs pretty fast (it
+takes 21 seconds for the indexer to index the human genome on the same
+processor).  Therefore the combination of the modules would allow user to
+retrieve and parse arbitrary records.
+
+=head1 ATTRIBUTES
+
+=head2 maxerrstr
+
+  Parameters: $maxerrstr (optional) - maximum number of characters after
+                offending element, used by error reporting, default is 20
+  Example:    $parser->maxerrstr(20);
+  Function:   get/set maxerrstr.
+  Returns:    maxerrstr.
+  Notes:
+
+=head2 input_file
+
+  Parameters: $filename for file that contains Entrez Gene record(s)
+  Example:    $parser->input_file($filename);
+  Function:   Takes in name of a file containing Entrez Gene records.
+              opens the file and stores file handle
+  Returns:    none.
+  Notes:      Attempts to open file larger than 2 GB even on Perl that
+                does not support 2 GB file (accomplished by calling
+                "cat" and piping output. On OS that does not have "cat"
+                error message will be displayed)
+
+=head1 METHODS
+
+=head2 new
+
+  Parameters: maxerrstr => 20 (optional) - maximum number of characters after
+                offending element, used by error reporting, default is 20
+              file or -file => $filename (optional) - name of the file to be
+                parsed. call next_seq to parse!
+              fh or -fh => $filehandle (optional) - handle of the file to be
+                parsed.
+  Example:    my $parser = Bio::ASN1::EntrezGene->new();
+  Function:   Instantiate a parser object
+  Returns:    Object reference
+  Notes:      Setting file or fh will reset line numbers etc. that are used
+                for error reporting purposes, and seeking on file handle would
+                mess up linenumbers!
+
+=head2 parse
+
+  Parameters: $string that contains Entrez Gene record,
+              $trimopt (optional) that specifies how the data structure
+                returned should be trimmed. 2 is recommended and

+  Function:   Takes in a string representing Entrez Gene record, parses
+                the record and returns a data structure.
+  Returns:    A data structure containing all data items from the Entrez
+                Gene record.
+  Notes:      DEPRECATED as external function!!! Do not call this function
+                directly!  Call next_seq() instead
+              $string should not contain 'EntrezGene ::=' at beginning!
+
+=head2 next_seq
+
+  Parameters: $trimopt (optional) that specifies how the data structure
+                returned should be trimmed. option 2 is recommended and
+                default
+  Example:    my $value = $parser->next_seq();
+  Function:   Use the file handle generated by input_file, parses the next
+                the record and returns a data structure.
+  Returns:    A data structure containing all data items from the Entrez
+                Gene record.
+  Notes:      Must pass in a filename through new() or input_file() first!
+              For details on how to use the $trimopt data trimming option
+                please see comment for the trimdata method. An option
+                of 2 is recommended and default

-
-=head1 PREREQUISITE
-
-None.
-
-=head1 INSTALLATION
-
-Bio::ASN1::Sequence is part of the Bio::ASN1::EntrezGene package.
-Bio::ASN1::EntrezGene package can be installed & tested as follows:
-
-  perl Makefile.PL
-  make
-  make test
-  make install
-
-=head1 DESCRIPTION
-
-Bio::ASN1::Sequence is a regular expression-based Perl Parser for ASN.1-formatted
-NCBI sequences.  It parses an ASN.1-formatted sequence record and returns a data 
-structure that contains all data items from the sequence record.
-
-The parser will report error & line number if input data does not conform to the
-NCBI Sequence annotation file format.
-
-The sequence parser is basically a modified version of the high-performance
-Bio::ASN1::EntrezGene parser.  However, I created a standalone module for sequence
-since it is more efficient to keep Sequence-specific code out of EntrezGene.pm.
-
-In fact it is possible to provide reading of all NCBI's ASN.1-formatted
-files through simple variations of the Entrez Gene parser (I need more
-investigation to be sure, but at least the sequence parser works well).
-
-Since demand for parsing NCBI ASN.1-formatted sequences is much lower than EntrezGene,
-this module is more like a beta version that works on the examples I checked, but
-I did not check all available records or data definitions.  The error-reporting
-function of this module has to be useful sometimes. :)
-
-=head1 SEE ALSO
-
-The parse_sequence_example.pl script included in this package (please
-see the Bio-ASN1-EntrezGene-x.xx/examples directory) shows the usage.
