+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+This document will describe how to install seti with graphics. 
+
+Make sure that boinc has been installed with graphics enabled. Follow
+the instructions Makefile.Readme in seti_boinc/client to make sure
+that Makefile.in.graphics will work with  your system. Rename
+Makefile.in.graphics as Makefile.in. From the seti_boinc/ directory
+run configure (or ./configure), then make. The executable will then be
+xseti[version and system info] and your app_info.xml file should
+reflect that name.

+setiathome(1)		User Commands		Version 6.90 - Feb 2011
+
+NAME
+    seti_boinc - the SETI@home client program
+
+SYNOPSIS
+    seti_boinc [options]
+
+DESCRIPTION
+    seti_boinc is the boinc version of the SETI@home client.
+    It runs under the BOINC client which downloads radio telescope data 
+    from a network server, analyzes the data looking for signals of 
+    extraterrestrial origin, and uploads results to the server, 
+    repeating this cycle indefinitely.  
+    See http://setiathome.berkeley.edu for more information.
+
+FILES
+    In order to use seti_boinc to analyze data from the seti@home project
+    you must first download the BOINC client software which is avalable
+    through the setiathome web page http://setiathome.berkeley.edu/
+    If used on a supported host platform, the BOINC client will automatically
+    download the most recent versions of the seti@home client software.
+
+    If you are compiling for an unsupported host platform, you may need to use
+    the boinc anonymous platform mechanism described at
+    http://boinc.berkeley.edu/anonymous_platform.php
+
+    The program generates several files with .sah extension
+    in the directory from which it's run.
+    These should not be modified.
+
+
+OPTIONS
+    -nographics
+	Do not show graphics while running.
+
+    -version
+	Show software version
+    
+SEE ALSO:
+	There is much more information to be found about the operation
+	of the client at the following WEB sites:
+		http://setiathome.berkeley.edu/
+		http://boinc.berkeley.edu/
+	with discussions of add-on programs and scripts to control
+	the BOINC client in various situations.
+
+        The most recent version of the seti_boinc source code can be found at
+	http://setiathome.berkeley.edu/
+
+	The most recent version of the official FFTW library can be found at
+	http://www.fftw.org/.  A version containing any modifications made for
+	SETI@home can be found at http://setiathome.berkeley.edu/
+	If you are unable to find it there, please contact Eric Korpela 
+	<korpela at ssl.berkeley.edu>.

+	This is a preliminary checkin for the project of including WU
+	analysis parameters in the WU header.  It also includes a routine
+	to read binary data WUs. 
+
+	In the end, all analysis parameters will have a default compile 
+	time value which can be supersede by values contained in the WU header.  
+	There will be no command line analysis parameters.
+
+	For this checkin, I added the following variables 
+	to the SETI_WORKUNIT_INFO (swi) structure.
+
+			spike_sigma_thresh;
+					gaussian_chi_sq_thresh;
+					gaussian_power_thresh;
+					gaussian_peak_power_thresh;
+					beam_width;
+					num_fft_lengths;
+					analysis_fft_lengths[MAX_NUM_FFTS]; 
+					chirp_resolution;
+					num_chirp_ranges;
+					ChirpFftTable_t chirp_fft_table[MAX_CFFT_PARAMS];
+
+	These replaced various standalone global variables and constants.  
+	Values for all of these variables are to be included in the WU header.
+
+	Because of all the moving of cfft parameters to swi, chirpfft_tab was removed from
+	the makefile.  This prompted to removal of the params assignment in  common_init()
+	and the necessity of passing the chirp resolution down to where it was needed -
+	InitChirpStep().
+
+	I added the following array sizers:
+		#define MAX_NUM_FFTS            64
+			#define MAX_CFFT_PARAMS         2
+
+	I added code to seti_parse_wu_header() to parse the new header values.
+
+	I added the following fields to PoTInfo_t.
+		GaussChiSqThresh;         
+			GaussPowerThresh;        
+			GaussPeakPowerThresh;  
+
+	In the output routines for each signal type, I added the temporary line:
+		outfile.flush();
+	until a outfile flushing is added to the boinc code.
+
+	The following existing members of swi were changed from float to double and associated
+	scanf()'s were changed to reflect this:
+			start_ra
+			start_dec
+			end_ra
+			end_dec
+			angle_range
+
+	There were some places where we were using strlen where sizeof should have
+	been used in seti_parse_wu_header().  I fixed these.
+
+	Added new routine read_bin_data() to read binary data.
+
+	Testing.  I dumped the generated chirpfft table and it matches the one 
+	generated by the current client.  I let the boinc app complete a WU
+	and the reported signals were correct within tolerances.  The reading
+	of binary data WUs has *not* been tested.
+
+	Still to do (among other things):
+		- make swi a global structure with compile time initialization.
+		- swi will include substructures for:
+			receiver parameters
+			recorder parameters
+			splitter parameters
+			analysis parameters
+		- create a new source file, seti_parse.C that will contain
+		  routines for parsing complex seti variables like the 
+		  above parameter lists.
+		- there are still a number of single precision floats
+		  in the code.  These should all be changed to doubles.
+		- XML-ize the signal lines in outfile.
+		- do away with command line options that are redundant with
+		  WU header items.
+		- add bounding tags to coordinate list in the WU header.
+		- add bounding tags for the different parameter groups (splitter,
+		  analysis, etc) in the WU header.
+		- it might be a good idea to not have the limits imposed by 
+		  MAX_NUM_FFTS and MAX_CFFT_PARAMS.  Instead, we could 
+		  have analysis_fft_lengths and chirp_fft_table be pointers
+		  to areas that we realloc as we parse the WU header.
+		- remove outfile.flush() from the signal outut routines.

+	the order of FFT lengths at a given chirp rate is reversed from that

+	Integrated Eric K's signal classes into the signal INFO structures (SPIKE_INFO
+	etc).  These structures (now classes) contain a signal proper (Eric's class)
+	plus ancillary data needed for "best of" tracking and graphics.  The handling
+	of the INFO objects required some code reoriganization to not be confusing.  
+
+	Signal INFO objects are print_xml()'ed to the state file at checkpoint time.
+
+	Best of signal objects are print_xml()'ed to the outfile upon exit from the 
+	main analysis loop.
+
+	This is a preliminary checkin.  More testing needs to be done.  There is a known
+	seg fault with an overloaded assignment operator (for class gaussian at least).
+	Some debug code and comments need to be pulled out.

+	Added "std_fixes.h", "win_config.h" and "config.h" to db directory
+	"std_fixes.h" should contain any routines missing from the std:: namespace on

+	TEST_VERSION)
+
+        unix_main.C
+
+
+8/28/2003 jeffc
+	Some (not very clean) mods to fix unix compilation.  There was 
+	a dependency of ~/bin/astyle which I removed by removing the indent  
+	logic from schema_to_class.in.  db/schema_to_class was not being made 
+	executable, even though this was specified in configure.ac.  I specified 
+	it in db/Makefile.in (twice, ugly) instead and this works.

+	of the state file.  We now initialize, then parse.

+
+9/4/03 jeffc  testing notes
+	I ran the client on the reference WU.  The results matched well with 
+	the reference result on triplets ans spikes.  The reference result contains
+	1 pulse and the new result contains no pulses.  The reference result contains
+	2 gaussians and the new result contains 1 gaussian that did not match well
+	with either of the reference gaussians.  The 2 reference gaussians are
+	really one gaussian detected twice over a shot time period.
+
+	I realized that the WU specified the new (correct) BW - 0.083 degrees.
+	I reran the client with the old 0.1 degree BW and the gaussian 
+	matched much better and I got a pulse but it did not match well.

+David  Sept 12 2003
+	- Moved SPIKE_INFO etc. from gdata.h to seti.h
+		Principle: everything relating to graphics should be surrounded by
+		#ifdef BOINC_APP_GRAPHICS
+	- Changed gdata from pointer to struct
+	- Defined new structs G_SPIKE_INFO etc. for graphics-related
+		signal info, to avoid template/constructor problems in graphics code
+	- Changed BOOLEAN to bool everywhere
+
+	Graphics now work in a rudimentary way.

+

+    No code changes.  This is the branch point for the beta.  The tag is:
+
+        setiathome-4.xx_all_platforms_beta
+
+    for both seti_boinc and boinc.  They both make on solaris without serious 
+    error and the resulting seti client links without error with the resulting 
+    boinc libs.  I ran the seti solaris 2.7 client on the reference WU and 
+    it produces a reasonable looking result file.  The science content has 
+    not yet been fully validated but that is OK.  "Best of" signals in the 
+    result looks good.  Checkpoint and restart work.
+	
+Eric K. 22 Sep 03
+
+    Checked in several mods to the setiathome-4 beta branch and the main branch
+    required to get the splitter working properly under boinc.

+	NOTE: there are three different structs for each signal type.  E.g.:
+		class gaussian (in schema_master.h)
+			has PoT array in unsigned chars
+		struct GAUSS_INFO (in seti.h)
+			contains "gaussian" as an element.
+			Also has score, bin, and the PoT array in floats
+		G_GAUSS_INFO (in gdata.h)
+			Has the minimal set of info needed to display a Gaussian.
+			A few fields from GAUSS_INFO, plus an "is_best" flag,
+			and a "dirty" flag (has this been displayed yet?)
+			Has a "copy" member function for copying from a GAUSS_INFO
+
+		The variable best_gauss (of type GAUSS_INFO) etc. (in analyzeReport.cpp)
+			stores the best Gaussian found so far (zero power if none)
+			Stored and read from the state file.
+		The variable SAH_GRAPHICS::gi (of type G_GAUSS_INFO)
+			stores the Gaussian currently being displayed (zero power if none)
+
+		Normally SAH_GRAPHICS::gi is copied from best_gauss,
+			and its is_best flag is true.
+		However, during analyze_pot(), SAH_GRAPHICS::gi is just the
+			most recent Gaussian computed, and is_best is false.
+
+	- Set the "dirty" flag of SAH_GRAPHIC's signals whenever copy to them
+		(i.e. don't need to do this separately)
+	- Remove "is_best" field of GAUSS_INFO etc.
+	- Copy PoT arrays using a for loop, not a memcpy()
+	- In graphics code: factor out the decision about which signal to display
+		into a separate function (choose_signal_to_display()).
+		Display a dirty signal if there is one,
+		otherwise rotate among those that are actually there.

+	- Built production executables and installed them in the

+	- Added the informix lib paths to the boinc master cron
+	  program.  This is needed for the assimilator.
+	- Note that at this point server side executables (and all 
+	  parts that make them up) have to be built on koloth (the 
+	  production host).  This is because koloth has a different 
+	  gcc (and libs) than our other machines.  Our standard gcc 
+	  is v 3.0.4 (bundled with libstdc++.so.3) while on koloth 
+	  we have gcc 3.3 (bundled with libstdc++.so.5).  Running on 
+	  koloth after building elsewhere gives:
+	  	fatal: libstdc++.so.3: open failed: No such file or directory
+	- Note that various Makefile.in's specify the mysql library as
+	  being /usr/local/mysql.  But for koloth it needs to be

+	  on koloth (a 64 bit mysql) gives

+      fails.  However, on solaris you cannot just say gcc -static as there
+      are dynamic only versions of some needed libs, namely libdl and 
+      libaio.  I tried to use the -Xlinker gcc option which theoretically
+      should allow us to specify the link (collect2) line in precise
+      detail.  But -lstdc++ kept showing up twice with one occurrence
+      being outside my -Xlinker -B -Xlinker static directive.  So I 
+      hand crafted a collect2 line and placed it in a file - collect2_line. 
+      Sourcing this file produces an executable that will load and run
+      across gcc versions (and solaris versions for that matter).  I
+      don't like it but it works.

+	  are instantiated via reset_high_scores() at run time.  reset_high_scores() 
+	  first deletes the signal info objects if they exist and then 
+	  (re)new's them into existance.  
+	  This change was needed because PoT array sizing within these objects
+	  is now a run time function.
+	- All '.' notation to get to signal info fields had to be changed 
+	  to "->" throughout the code.
+	- Moved the signal info method code from seti.h (where it was inline)
+	  to seti.cpp (where it is not).

+     right before the call to sah_graphics.worker_thread_init()
+     or in sah_graphics.worker_thread_init() itself.  Note that
+     at this point, graphics initialing happens *before* we

+          is now a required command line parameter (-scidb=).  We are using
+          the new db_change() routine to attach to the desired DB.
+        - The project directory was hard coded in config.h (PROJECTDIR)
+          and is now a required command line parameter (-projectdir=).
+        - the download directory was hard coded in splitparms.h as 
+          WU_DIR.  This was changed to WU_SUBDIR which equates to
+          "download" and concatenated to the projectdir to get the 
+          fully qualified download directory.

+Eric K 30 June 2004
+    - Removed "using" directives from header files.  "using"
+      directives should not be used in header files for the following reasons.
+      - A "using namespace" directive cannot be revoked for any source file
+	including the header.  It forces the use of the namespace regardless of
+	the consequences.
+      - Dropping the namespace qualifier on STL templates ambiguates the
+        resolution of template functions.  (How many C libraries or headers 
+	have you seen that define the function min()?)
+      - Reducing typing is not a good reason to drop namespace qualifiers any
+	more than it would be a good idea to "#define p printf"
+      - Namespaces exist for a reason.  
+      - It's acceptable to have "using" directive in a source file, since it
+	won't affect other files.  It's better to have "using std::string;"
+	directives than "using namespace std;" for hopefully obvious reasons.

+	  wait_for_db_wus_ondisk(). All other calls to this routine return
+ 	  immediately, indicating a need for work.  Further, while in the

+
+Jeff  09 Sep 2004
+    - Change to the validator to handle the case where one or more of the result files
+      for a WU's result set are missing.  Before this change this state would result
+      in this WU and it's results never getting looked at again.  No science, no
+      credit.
+
+      This is coordinated seti_boinc / boinc change.  This note is repeated in
+      the boinc checkin_notes. 
+	
+      seti_boinc changes:
+	- get_result_file(), if it cannot read the result file, tries to read the 
+	  directory where the result file should be.  If it can read the directory,
+	  it returns ERR_FOPEN, as before.  If it cannot read the directory, it
+	  resturns ERR_OPENDIR.   ERR_OPENDIR in this context signals a possibly
+	  transient problem.  Upon a successful result read, it sets sah_result.have_result
+	  (a new data member as of this change) to true.
+	- check_set(), upon return from get_result_file() :
+		- sets result.validate_state to VALIDATE_STATE_ERROR (a new state
+		  as of this change) and retval to zero if there is a nonzero
+		  retval from check_set() and it is not ERR_OPENDIR.  It then
+		  continues.
+		- otherwise just continues.
+	  check_set() then determines if any IO errors brought the result count
+	  below wu.min_quorum.  If not, it continues.  Otherwise it returns.
+	  In all subsequent logic any results for which sah_result.have_result == false
+	  are skipped.  Note that the result and the sah_result vectors are associated.
+
+        validate/
+		sah_result.h
+		sah_validate.cpp
+		sah_boinc_db.cpp
+
+	boinc changes:
+	  - new validate state VALIDATE_STATE_ERROR.
+	  - in the enumeration for check_set(), we now include a clause to check for
+	    VALIDATE_STATE_INIT in order to ignore results set to VALIDATE_STATE_ERROR.
+	    This enumeration query now matches that for check_pair().
+          Note that the only possible retvals from check_set() are now zero or
+	  ERR_OPENDIR.
+	  Note that logic to retry possibly transient errors still needs to be done.
+	  Also left to be done is a transitioner change to subtract the number of
+	  results in state VALIDATE_STATE_ERROR from the count of active results.
+	  The latter change is needed to stimulate the production of additional results
+ 	  for the affected WU.

+    - Some time ago a bug was fixed that reduced the amount of time it takes
+      to do pulse searching but the progress unit computation remained tuned
+      to the bug.  This resulted in an overestimation of the percentage of 
+      total processing time spent in pulse searcing.  We do the most intensive
+      pulse searching at the start of a WU so what the user sees is an early
+      and false jump in percentage done.  This change is just a retuning of 
+      PulseProgressUnits().  I changed:
+          return(PulsePoTLen * PulsePoTLen * log(PulsePoTLen) * FftLen / 0.65e6);
+      to:
+          return(PulsePoTLen * PulsePoTLen * log(PulsePoTLen) * FftLen / 2.65e6);

+        calculation of LMST.  This bug is what led to some RA's being >= 24.

+	          This was tested by comparing assimilator precession results
+		  to those obtained by the online FUSE precession calculator:
+		  http://fuse.pha.jhu.edu/cgi-bin/precess_tool
+		  There was agreement to under an arcsecond.  This was also
+		  tested under RA wrap conditions.  Here are 2 examples:
+		  obs RA      obs decl    sah precession          obs time                precession by fuse calc         sah-fuse diff in arcsec

+
+		- calculation of the signal's barycentric frequency. 
+		  This also uses serendip code.  Frequency shifts were within
+	          the expected range (max ~= 142KHz) but no independent tests were done.
+
+		- calculation of the cubic pixel number.  This was tested by
+		  reversing the qpix calculation and comparing the resulting
+		  RA/Decl with the the original.  There was agreement to a max
+		  deviation of ~1.3 arcminutes which is OK because the qpix reversal
+		  gives you the pixel center coordinates which is a max of ~1.3 arcmin
+		  arcminutes from the pixel edge (given nside=2048).  Most diviations
+		  on reversal were smaller than this.

+    - Fix bug in database code.  The informix interface was expecting blobs to
+      be presented in hex format rather than raw binary.  So informix interface
+      was attempting to translate the code to binary.  In addition there was a
+      bug in the translating code such that only characters 'a'-'f' and 'A'-'F'
+      were being translated.  The result was that most of the blob data were
+      reassigned blob[i]=(blob[2*i]*16+blob[2*i+1])&0xff.
+    - For better debugging, I changed the sqlifx.ec chk_status() macro (which
+      included a RETURN!!!  Yuck!) into a boolean function.
+    - Since the informix SQLCODE variable (and the identical sqlca.sqlcode)
+      aren't available to the debugger, I replaced accesses to this variable
+      with calls to sql_error_code().
+    - Since when errors were detected, sql_close() was being called which
+      cleared the error code.  We've added a function sql_last_error_code() to
+      return the last non-zero error code and sql_reset_error_code() to reset
+      the last non-zero error code.  There's still some work to do as far as

+
+	- Assimilator changes:
+		- If there is no canonical result for a WU, return 0.  This will cause
+		  the boinc assimilator to mark the WU as assimilated and it will then
+		  have it's file's and it's DB record(s) deleted.   No canonical result 
+		  means that  too many results were returned with no concensus.
+		- use sql_last_error_code() rather than sql_error_code(), as the latter
+		  always returns 0.
+		- I a result insert get an informix error -239, return 0.  This will cause
+                  the boinc assimilator to mark the WU as assimilated and it will then
+                  have it's file's and it's DB record(s) deleted.  A -239 (uniqueness 
+		  violation, in this case on sah result field boinc_result) means that 
+		  we have already inserted the canonical result for this WU.  This
+		  should "never" happen but maybe with aome odd stop/start combo it does.
+		- If the bad value check detects a bad value in a signal, replace this
+		  bad value with a recognizable marker.  This is in addition to flagging
+		  the signal in the rfi_found field.  This value replacement is needed
+		  because some bad values cannot be interted into the DB.  The marker
+		  value is -91.0.  This is an impossible value for ra, decl, time, and freq.

+    - Changed includes of C headers to includes of C++ headers.  (i.e. we now 
+      include <cmath> rather than <math.h>)
+    - Modified malloc_a() to use native aligned allocation routines if 
+      available.
+    - Removed explicit use of _aligned_malloc on _WIN32 platforms since 
+      malloc_a() will use _aligned_malloc().
+    - Defined type sah_complex which is compatible with the FFTW complex 
+      data type.  Complex arrays that used to be defined a float arrays are
+      now of type sah_complex.  Code accessing these arrays has been modified
+      where necessary.
+    - Added mods to allow the function prototypes in sincos.h to work if these
+      functions are present, but not in the system <math.h> header.
+    - Modified the method by which the chirp table is computed. The goal is 
+      to have the drift be less than 1 bin over the duration of interest 
+      to the analysis.  In the case of gaussians that duration is 2 beam 
+      crossings.  In the case of pulses it's one beam crossing.  In the 
+      case of spikes it's one fft length.  This should pick up 1.5 dB in
+      sensitivity to gaussians, pulses and triplets.  We could pick up another
+      0.25 dB with another doubling of this duration, but I think we've reached
+      diminishing returns.
+    - Replaced repeated allocations of WorkData in the main loop with one
+      allocation prior to loop entry
+    - Made main processing loop compatible with FFTW.  The configure script 
+      now detects the FFTW library and header files and if both are available 
+      USE_FFTW is defined in "config.h".  This define determines which FFT is
+      used.

+    Splitter related changes.
+    - account for new command_line parm in create_work() - we just pass NULL.
+    - changed all instances of safe_strncpy() to strlcpy(). 
+    - change the app config file name to sah_enhanced_config.xml.

+    - The assimilator now uses the settings ID that is embedded in the wu/result name
+      to get to the analysis_config and receiver_config tables.  If the  settings ID
+      has not changed from one result to the next (normally true until the enhanced client
+      gets released) then we do no DB accessing.  This replaces the logic whereby
+      we were reading the wu and wug for each result.
+    - Both the enhanced and old splitter were previously modified to embed the settings ID
+      into the wu/result names.

+    - Templated signal insertion.  There were several other small code changes secondary 
+      to this.
+    - if (appid == 2) signal.reserved = 1.  This is temporary for enhanced rollout plus
+      DB correction.  The correction code needs to know is the signals were returned
+      by an enhanced app or not.
+

+    - Changed the type of q_pix in all 4 signal table schemas from integer to int8.
+    - The assimilator now inserts signals with "n_pix", a 64 bit integer.  It
+      contains "q_pix" in the high order 32 bits and frequency with a resoltion of 10 Hz
+      in the low order 32 bits.  All floating point numbers are cast (ie floored) to
+      integers in this processed.

+    - Changed the frequency to fpix conversion from a cast-to-long to
+      a round function:
+           inline long round(double x) {return long(floor(x + 0.5f));}
+      Casts from floating point to integers are always equivalent
+      to either (int)floor() or (int)ceil(), depending on the rounding
+      mode of the platform.

+5/31/07 korpela
+    - Increased version number to 5.20  !!! THIS IS NOT YET A WORKING BUILD.  I
+      WILL TAG IT WHEN IT WORKS !!!
+    - Lots of changes by Joe Segur to implement optimized algorithms.
+    - Current build finds extra triplets.  Tracking that down now.
+    - This might not build on Visual Studio.
+
+      Significant changes are:
+
+1. Modified Pulse finding. This includes both algorithmic improvements
+effective on all systems, and the possibility of using vectorized
+folding subroutines on systems with SIMD capability. Files:
+pulsefind.cpp, h       - primary changes
+analyzeReport.cpp, h   - minor supporting change
+AKfoldSSE.cpp          - new
+
+The algorithmic improvements include:
+
+- The sums produced in the folding subroutines are not divided by
+ the fold level, saving a small amount of time.
+- The invert_lcgf() caching saves the display threshold value rather
+ than the report threshold, and also doesn't scale by fold level.
+ This allows a quick comparison where only for the approximately 1%
+ of cases where display threshold is reached does report threshold
+ need to be calculated and checked.
+- Calculations of period values are kept in integer form and only
+ converted to floating point for reporting.
+- The memcpy() of Pulse PoT arrays before the initial fold by 3, 4,
+ or 5 is removed.
+- The sequence of folding operations for Pulse PoTs of length 511
+ and shorter is cached. This reduces the 3 nested loops to a
+ single faster loop for most cases where the loop overhead was using
+ a significant fraction of the time for folding.
+- The default folding subroutines are optimized for FPU and coded to
+ encourage efficient instruction scheduling by the compiler.
+
+In support of SIMD folding:
+
+- Outputs of the folding subroutines are written 16 byte aligned so
+ the next fold can use aligned loads. (This is also more cache-friendly
+ even when SIMD isn't available).
+- Because SIMD routines are not very efficient for the shortest PoT
+ lengths, particularly those not divisible by 4, the choice of routine
+ for each length up to 31 is table-driven. (Again, this proved to also
+ be a help for the default FPU optimized routines).
+
+Overall, the algorithmic improvements approach a 10% improvement in
+total crunch time, SIMD folding another 10%.
+
+2. Transpose changes and additions:
+
+- Transpose is only done for chirp/fft pairs for which Gaussian, Pulse,
+ or Triplet searching will be done.
+- Changed testing from 512x2048 to 16Kx64 which is used much more. That
+ had very little effect on my Pentium-M with 1 MiB L2 cache, more on
+ my Willamette P4 with 256 KiB L2, and most on my Pentium-MMX with
+ 256 KiB very slow L2 on the motherboard.
+- Added a non-prefetch version of v_vTranspose4. It's faster on my
+ Willamette P4 system than the original, though slightly slower on
+ my Pentium-M system. (I also did the same for the GetPowerSpectrum
+ routines with similar effect.)
+- Added another vectorized 4x4 subtranspose which differs mainly in
+ using non-temporal writes, plus a variety of functions which use
+ it. One of those always measures fastest on my two systems with SIMD
+ capability, by a 30% or more margin.
+
+files:
+analyzeFuncs.cpp, h
+analyzeFuncs_sse.cpp, h
+analyzeFuncs_vector.cpp, h
+
+
+3. Chirping changes and additions:
+
+- Modified CalcTrigArray() so when going two or more ChirpRateInd steps
+ it only transits the two 16 MiB arrays once.
+- Modified testing so the change from negative to positive chirp goes
+ two steps up. That provides a better overall speed approximation,
+ though it's only a rough match to the number of chirp indices which
+ are skipped in typical WUs.
+- Modified testing to start at chirp index 27040 so the error check is
+ including the difficult angles of over 262144 which make single
+ float rounding produce fractional input to the SinCos approximation
+ with only 5 bits of precision.
+- After testing, if TrigArray isn't chosen then InitTrigArray() is not
+ called again.
+- Added SSE3, SSE2, and SSE1 versions derived from Alex Kan's sources.
+- Added an FPU version patterned after the SIMD versions; quick rounding
+ and non-branching polynomial SinCos approximation. On my systems it's
+ quicker than TrigArray and of course it doesn't need the extra 32 MiB
+ array space. This one isn't yet in a lunatics.at release, but Simon
+ has built pretest versions so I'll find out soon if it's faster on
+ AMD systems.
+
+Note 1: The DevC++ builds do a good job of making main() align per the
+ default preferred_stack_boundary of 2^4, but not the worker thread.
+ To work around that so the SIMD chirping wouldn't crash I added a
+ hack near the beginning of worker() to force the stack pointer to
+ a multiple of 16 for GNUC builds. The calculations in those SIMD
+ routines are complex enough that there are register spills to
+ temporary stack variables, so the kind of aligned alloca() used in
+ analyzeFuncs_x86_64.cpp isn't adequate, I did try that. I suppose
+ adding enough additional aligned variables could make that approach
+ work, but I'm reluctant to modify those well-tested routines more
+ than strictly necessary.
+Note 2: The "const" in float4 constant definitions seems to conflict
+ with the MinGW intrinsics. I'm not sure why, I thought the C style
+ cast to (void *) used in the *mmintrin.h files should work, so I
+ just removed "const" for now.
+
+files:
+x86_float4.cpp, h             - modified
+analyzeFuncs.cpp, h           - modified
+analyzeFuncs_vector.cpp, h    - modified

+analyzeFuncs_fpu.cpp          - new
+analyzeFuncs_sse2.cpp         - new
+analyzeFuncs_sse3.cpp         - new
+
+
+4. Miscellaneous:
+
+- In seti.cpp, h added save to and restore from state file of individual
+ signal counts, plus relocated the final report of those values there;
+ it's now called before both the normal exit in analyzeFuncs.cpp and
+ the overflow exit in worker.cpp.
+- In analyzeFuncs.cpp added output of a CUSTOM_STRING (if defined) to
+ the beginning of stderr, and a restart indication with the progress
+ in percent.
+- In worker.cpp replaced the try/catch for parsing the state file with
+ a check for existence of that file, same as in my 517STxx builds from
+ the "Builds for unexplained error test" NC forum thread.
+- In analyzeFuncs_vector.cpp, h restructured the tables of functions to
+ test to a single table for each type, adding a field indicating what
+ CPU capabilities are required for the function. Also added a routine
+ to set a variable to the host capabilities; the testing routines
+ compare those and don't try unsupported routines.

+    The assimilator now populates a new table - hotpix.  Rows consist of 
+    a qpix and the time of assimlation.  For each result assimilated
+    a unique list of qpixes for the signal set is constructed.  For each
+    of these qpixes a new row in hotpix will be inserted, unless there is
+    already a row for that qpix, in which case the time will be unpdated.

+This readme will explain the differences between Makefile.in and Makefile.in.graphics, 
+as well as usage and possible changes to be made to be system compliant.
+
+To use Makefile.in.graphics just rename it Makefile.in and configure seti_boinc. The 
+changes between the original Makefile.in and Makefile.in.graphics are:
+
+CFLAGS: addition of -DBOINC_APP_GRAPHICS
+BOINC_INC: addition of -I/usr/openwin/share/include (possibly extraneous)
+	   addition of -I$(BOINCDIR)/boincglut/include
+		       -I../jpeglib
+CXX, CC: addition of -g debug option (not vital)
+GUIOBJS: addition of all the files prexisting under OBJS, as well as
+		graphics_api, x_opengl, grahpics_data from ../../boinc/api and sah_gfx_base, sah_gfx, and gdata (all .$(OBJEXT))
+GUILIBS: addition of -lX11, -lXmu, -L$(BOINCDIR)/boincglut/lib/glut -lboincglut
+         -L../jpeglib -ljpeg 
+	THE FOLLOWING ADDITION IS SYSTEM DEPENDENT: the location of the GL
+	and GLU libraries on the system (ie /usr/X11R6/lib in Linux, 	
+	-L/usr/openwin/lib/ on Solaris) followed by -lGL and -lGLU
+all: change PROGS to GUIPROG (possible to have both? I couldn't figure out how)
+GUIPROG: addition of main.$(OBJEXT) to dependencies
+	 addition of main.$(OBJEXT), gutil.$(OBJEXT), reduce.$(OBJEXT), 
+	$(LIBS), -lpthread to rule
+
+The only thing that should need to be changed is the location of the GL libraries 
+as mentioned, but it's possible that other changes should be made.

+// General Notes
+
+// Concerning the gaussian function macro EXP:
+// The EXP macro defined here is used to generate the gaussian function
+// f(x) = exp(-(C * x^2 / sigma^2)) in both fakedata and gaussfit.  Sigma
+// is in arbitrary units and simply gives the width of the gaussian.  We
+// give it a particular meaning by properly setting the value of  the
+// constant C.  The meaning we give sigma here is that 2sigma is the
+// half power beamwidth of the telescope.  We solve for C when x = sigma
+// and f(x) = 1/2.  Thus we have f(x) = exp(-C).  Taking the natural log
+// of both sides gives us ln(1/2) = -C.  And so C = -ln(1/2) = 0.693.

+31st May 2014 - Added folder structure for ITranspose and IPowerspectrum abstract base classes
+-----------------------------------------------------------------------------------------------------------
+30th May 2014 - Initial cut, for refinement as derived classes take shape 
+(FFT's will be first cab off the rank, via IFFT abstract class deriving from this, followed by fftw, oura,
+cufft, oclfft and naive dft implementation classes)
+- ICoreSigProc: Abstract (pure virtual) base template class
+template parameters <_Tin, _Tout> are input and output types respectively.
+execute() member function is pure virtual, for polymorphic use of derived classes in pipelines.
+derived classes, abstract or otherwise, should either feed pointers through using the fully
+specified constructor, or the fairly useless default constructor will be used.  Will probably disable that default constructor later.
+- Fully templatised so that higher & possibly arbitrary precision gold reference implementations
+can be easily injected in test pieces, regression tests etc, while using the same class library.
+-----------------------------------------------------------------------------------------------------------
+24th May 2014, (Part 2) [Added IPulse base class, derived from ISearch]
+- Folders for some candidate derived generic classes, for devices, signal processors, and pipelines.
+IDevices:  CPUs, GPUs, and Remote nodes (future RPC)
+ICoreSigProcs: Generalisations of major search algorithm processing steps.
+IPipelineSigProcs: Generalises different levels of parallelism that may be used
+-- IFFTPipeline: Might be asked to process one or more FFT's in a given CFFT pair, up to a whole CFFT
+-- ICFFTPipeline: Might be asked to process from one CFFT up to a whole Chirp full.
+-- IChirpPipeline: Might be asked to process from one Chirp, up to a whole task.
+-- ITaskPipeline:  Might process from one to many tasks at once (future)
+
+Jason Groothuis ( contact at jgopt dot org )
+-----------------------------------------------------------------------------------------------------------
+24th May 2014, (Part 1)
+ Initial trial folder structure (only), mirroring top level of proposed class hierarchy (currently inactive/unused).  For dropping in candidate classes for refinement and future use. 
+
+Due to a lack of naming convention for C++ Abstract Classes, I'll use common capitalisation for implementation classes, and prefix with 'I' for abstract ones.  Will stay fairly flexible this early, should namespace conflicts arise here. (i.e. don't expect stable interfaces yet )
+
+Expect containers/enumeration at high level for easing future development.
+
+ICoreSigProc- Abstract signal processor class,
+- parent/ancestor of all derived FFT, Chirp, Spike, Triplet, Pulse, Gaussian and Autocorrelation generic classes.
+- Another generic abstraction level under this one for wrapping implementations below.
+
+IDevice- Abstract Processing resource class,
+- parent/ancestor of all compute devices capable of processing any portion of core signal processing in any fashion
+- Another generic abstraction level under this one, for wrapping different kinds of device.
+
+IPipelineSigProc- Abstract class pipelining of ICoreSigProcs and IDevices
+- Abstracts allowable processing order/reductions of results etc, and devices
+- represents the processing algorithm at the highest levels
+- implementations and generalisations underneath may represent totally different 'ways' of arriving at a reference 'answer'.

+//
+// Differences from the implementation in the paper:
+// 1. The arguments are not scaled by 1/(2 pi) because the original chirp
+//    algorithm multiplies the chirp rate by (2 pi).
+// 2. The slower version of the algorithm has been used (as if FASTER_SINCOS
+//    had not been defined for the code in the paper).
+// 3. The loop has been unrolled once so the variables have been renamed to make
+//    things more readable.
+// 4. The "struct phase" data type is not used.
+// 5. The rounding of the input value to the range (-0.5, 0.5) is done in
+//    double-precision as mentioned above, and not via Altivec.

+// Fixed a problem with the << operator for db_table.h.
+// Also altered << operator to stop looking for the start tag after it is found
+// and to not look for the stop tag until after the start is found.
+// Modified xml_match_tag() to not search zero length strings.
+//
+// Revision 1.3.2.1  2005/10/17 22:14:48  korpela
+// Fixed bugs with XML formatting and CSV vector input.  The XML formatting bug
+// fixes were submitted by Tetsuji "Maverick" Rai.  The CSV input problem was due
+// to my misunderstanding of the istream::operator void *().  I had thought the
+// operator returned NULL if the past operation had failed.  Instead it returns
+// NULL if the NEXT operation will fail.

+ * Revision 1.2.4.1  2006/01/13 00:37:57  korpela
+ * Moved splitter to using standard BOINC logging mechanisms.  All stderr now
+ * goes to "error.log"
+ *
+ * Added command line parameters "-iterations=" (number of workunit groups to
+ * create before exiting), "-trigger_file_path=" (path to the splitter_stop trigger
+ * file.  Default is /disks/setifiler1/wutape/tapedir/splitter_stop).
+ *
+ * Reduced deadlines by a factor of three.  We now need a 30 MFLOP machine to meet
+ * the deadline.

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also link it with them as well. e.g. you should link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threads programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
+#   (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+# ----------------------------------------------------------
+#      David Shaw <dshaw@jabberwocky.com>   Jun-21-2005
+#
+# Checks for libcurl.  DEFAULT-ACTION is the string yes or no to
+# specify whether to default to --with-libcurl or --without-libcurl.
+# If not supplied, DEFAULT-ACTION is yes.  MINIMUM-VERSION is the
+# minimum version of libcurl to accept.  Pass the version as a regular
+# version number like 7.10.1. If not supplied, any version is
+# accepted.  ACTION-IF-YES is a list of shell commands to run if
+# libcurl was successfully found and passed the various tests.
+# ACTION-IF-NO is a list of shell commands that are run otherwise.
+# Note that using --without-libcurl does run ACTION-IF-NO.
+#
+# This macro defines HAVE_LIBCURL if a working libcurl setup is found,
+# and sets @LIBCURL@ and @LIBCURL_CPPFLAGS@ to the necessary values.
+# Other useful defines are LIBCURL_FEATURE_xxx where xxx are the
+# various features supported by libcurl, and LIBCURL_PROTOCOL_yyy
+# where yyy are the various protocols supported by libcurl.  Both xxx
+# and yyy are capitalized.  See the list of AH_TEMPLATEs at the top of
+# the macro for the complete list of possible defines.  Shell
+# variables $libcurl_feature_xxx and $libcurl_protocol_yyy are also
+# defined to 'yes' for those features and protocols that were found.
+# Note that xxx and yyy keep the same capitalization as in the
+# curl-config list (e.g. it's "HTTP" and not "http").
+#
+# Users may override the detected values by doing something like:
+# LIBCURL="-lcurl" LIBCURL_CPPFLAGS="-I/usr/myinclude" ./configure
+#
+# For the sake of sanity, this macro assumes that any libcurl that is
+# found is after version 7.7.2, the first version that included the
+# curl-config script.  Note that it is very important for people
+# packaging binary versions of libcurl to include this script!
+# Without curl-config, we can only guess what protocols are available.

+// Title      : fakedata.c
+// Programmer : Jeff Cobb / David Anderson
+// History    : 12/13/95 - first release
+//            : 10/25/05 - Modified for setiathome_enhanced Eric Korpela
+// Copyright (c) 1998 University of California Regents
+
+// Credits for seti@home reference package:  
+// algorithm design: Dan Werthimer (UCB),  
+//                   Mike Lampton, (UCB),  
+//                   Charles Donnelly (UCB),

+// reference code programming: Jeff Cobb  
+// seti@home network design and programming: David Anderson
+
+// This program is to be used to generate fake digital data
+// for testing seti@home algorithms.  It generates random
+// noise embedded with any of the following signal types:
+// - continuous
+// - pulsed
+// - chirped
+// - showing an gaussian power profile over time
+// The randomness of the noise can be colored by:
+// - change in noise amplitude over time
+// - favoring certain frequencies (changing noise
+//   amplitude over frequency)
+
+// The signal to noise ratio you want to use to emulate a setiathome work
+// unit depends upon the signal type and the FFT length you want to find it at.
+// For example if you want to build a gaussian that is 5 times the noise power
+// at an FFT length of 16384 you should specify a noise amplitude of 1 and
+// a gaussian amplitude of 5/sqrt(16384) (about 0.04).  If you want to specify
+// a spike of 30 times the mean noise power at an FFT length of 128k you would
+// specify a sine wave of amplitude 30/sqrt(128k) (about 0.083).
+
+// The output file contains
+// the number of data points and an array of floating
+// point numbers representing power over time.
+// That the array is a series of complex values,
+// using 2 array elements for each data point.
+// Real parts are held in even elements (starting with [0])
+// and imaginary parts are held in the adjacent odd elements.
+
+// options:
+//
+// -sr n
+//	samples per second
+// -dur x
+//	duration of data (seconds)
+// -sine amp freq chirp start end
+//	inject a sine wave, amplitude amp
+//	freq: frequency at center of time interval
+//	(note: freqs must lie in [-sr/2, sr/2]
+//	chirp rate in Hz/sec
+//	NOTE: chirp is applied starting from time 0
+//	(not necessarily from the start of the sine wave)
+//	Start and end times; if zero, whole duration
+// -noise amp
+//	inject noise of amplitude amp;
+// -gauss amp midpt sig freq chirp
+//	Inject a Gaussian signal with the given amplitude and midpoint,
+//	halfpower width (seconds), frequency (Hz), chirp rate (Hz/sec)
+// -pulse period duty
+//      Inject a pulse signal with the given period (seconds) and duty cycle (percent).  It
+//      is "encased" in the Gaussian envelope determined by the -gaussian parameters
+// -ascii
+//	generate ascii data
+//	default: 1-bit output samples (binary).
