-<H2>Funtools ChangeLog</H2>
-
-<P>
-This ChangeLog covers both the Funtools library and the suite of
-applications. It will be updated as we continue to develop and improve
-Funtools.  The up-to-date version can be found <A
-HREF="http://hea-www.harvard.edu/RD/funtools/changelog.html">here</A>.
-
-<H2>Beta release 1.0.b28 (06/26/01)</H2>
-<UL>
-
-<P>
-<LI> In funcnts, removed extra new-lines from the primary table,
-inadvertently added in cases where zero-area rows are skipped.
-
-<P>
-<LI> Added code to support columns in binary tables that do not have names.
-
-<P>
-<LI> Changed the ds9 radial plot so that the radius (x value) for each
-plotted point is taken to be the middle of the annulus, (Rin+Rout)/2,
-instead of just the inner annulus, Rin.
-
-</UL>
-
-<H2>Beta release 1.0.b27 (06/21/01)</H2>
-<UL>
-
-<P>
-<LI> Added missing new-lines in funcnts primary tables that did not
-have -r switch.
-
-<P>
-<LI> Filtering with dynamic shared objects (gcc only) now links the
-region code into the shared object, instead of relying on finding the
-region code in global space.
-
-<P>
-<LI> A few minor changes to column headers in funcnts.
-</UL>
-
-<H2>Beta release 1.0.b26 (05/21/01)</H2>
-<UL>
-<P>
-<LI> Fixed funcnts to work properly when the background region
-overlaps the source and therefore explicitly excludes the source.
-It was simply ignoring the source regions in such a case.
-
-<P>
-Added a second DS9 init file, funcnts2.ds9, which contains funcnts
-and radial profile routines that work from the image stored in DS9's
-memory, rather than the original FITS file. This is useful in cases
-where no original FITS file exists (e.g., a temp file was created
-by a program and sent to DS9).
-
-<P>
-<LI> Fixed funcnts so that region specified with a variable number of
-arguments must come last (as is the case with panda and the n=
-accelerator). Thus, a region specification such as "pie 504 512 10 20
-30 & circle 504 512 10" is now properly an error.  Using "circle 504 512 10
-& pie 504 512 10 20 30" instead ensures that the circle is applied to
-each pie.
-
-<P>
-<LI> Fixed funcnts output of radii/angles when boolean expressions
-such as "pie & annulus" are specified.
-
-<P>
-<LI> Enhanced funcnts so that -r outputs valid radii for circular regions.
-
-</UL>
-
-<H2>Beta release 1.0.b25 (4/19/01)</H2>
-<UL>
-
-<P>
-<LI> Added support to funtable to generate a FITS binary table
-from an image. By default, a 3-column table is generated, where the
-columns are "X", "Y", and "VALUE". For each pixel in the image, a
-single row (event) is generated with the "X" and "Y" columns assigned
-the dim1 and dim2 values of the image pixel, respectively and the
-"VALUE" column assigned the value of the pixel. If the -i
-("individual" rows) switch is specified, then only the "X" and "Y"
-columns are generated. However the number of rows (events) are written
-out for each image pixel is equal to the value of that image pixel(or
-1, whichever is larger).
-
-<P>
-<LI> Added -z switch to funcnts to display shapes in primary table
-that have no area. This is useful when automatic processing assumes
-that there are a set number of rows.
-
-<P>
-<LI> Reworked how the "$region" column is handled. A "$region" column
-can now be added to a table already having a "region" column.  If a
-"region" column already exists, the new column will be "region1". If
-that exists, we try "region2", etc.
-
-<P>
-<LI> Added the header parameters EXTNAME="IMAGE" and EXTVER=1 when an
-image extension of created automatically.
-
-<P>
-<LI> When funcnts is run with -r, the rad1, rad2, ang1, and ang2 columns
-are filled in with "NA" if the shape is not annulus, pie, or panda (instead
-of being left blank).
-
-<P>
-<LI> Changed funcnts to display arc-sec/pixel instead of degrees/pixel in the
-output header.
-
-<P>
-<LI> Fixed bug in FunColumnSelect() that prevented a new table from
-being created that consists only of new columns.
-
-<P>
-<LI> Fixed processing of blank values in FunImageRowGet() (was a SEGV).
-
-<P>
-<LI> Fixed fundisp processing of images (SEGV upon completion, trying to
-free space only used by tables).
-
-<P>
-<LI> Fixed bug in funcalc which left executable in /tmp space if -n
-(no execute) was specified.
-
-<P>
-<LI>Fixed various bugs processing raw event files, especially on
-little-endian machines and reading these files via stdin.
-
-<P>
-<LI> Changed rad1, rad2 columns to radius1, radius2 in funcnts.
-
-<P>
-<LI> Purified dynamically loaded filter code (since purify now can work
-with gcc).
-
-</UL>
-
-<H2>Beta release 1.0.b24 (03/26/01)</H2>
-<UL>
-
-<P>
-<LI> First release of <B>funcalc</B>, the Funtools table calculator.
-funcalc is a calculator program that allows arbitrary
-expressions to be constructed, compiled, and executed on columns in a
-Funtools table (FITS binary table or raw event file). It works by
-integrating user-supplied expression(s) into a template C program,
-then compiling and executing the program. funcalc expressions
-are valid C statements, although some important simplifications (such
-as automatic declaration of variables) are supported.  
-
-Within a funcalc expression, reference is made to a
-column of the <B>current</B> row using the C syntax
-<B>cur->[colname]</B>, e.g. cur->x, cur->pha, etc. Local scalar
-variables can either be defined using C syntax at very the beginning
-of the expression, or else they can be defined automatically by
-funcalc (to be of type double). Thus, for example, a swap of
-columns x and y in a table can be performed using either of the following
-equivalent funcalc expressions:
-<PRE>
-  double temp;
-  temp = cur->x;
-  cur->x = cur->y;
-  cur->y = temp;
-</PRE>
-or:
-<PRE>
-  temp = cur->x;
-  cur->x = cur->y;
-  cur->y = temp;
-</PRE>
-When this expression is executed using a command such as:
-<PRE>
-  funcalc -f swap.expr itest.ev otest.ev
-</PRE>
-the resulting file will have values of the x and y columns swapped.
-Many other features are available in funcalc to make table
-manipulation easy. See the Funtools program.html documentation.
-
-<P>
-<LI> First release of the <B>funtools.ds9</B> set-up file for adding
-Funtools analysis programs to the DS9 Analysis menu.  This set-up file
-is installed in the same bin directory where Funtools programs are
-installed and can be loaded into DS9 from the <B>Load Analysis
-Commands ...</B> option of the <B>Analysis</B> menu.  Alternatively,
-you can tell DS9 to load this file each time it starts by adding the
-file to the <B>Edit</B>-><B>Preferences</B>-><B>Analysis
-Menu</B>-><B>Analysis File</B> menu option.
-
-<P>
-<LI> Added support for non-integral binning of binary tables. The bincols
-specifier on the command line now can take the form:
-<PRE>
-  bincols=([xname[:tlmin[:tlmax:[binsiz]]]],[yname[:tlmin[:tlmax[:binsiz]]]])
-</PRE>
-where the tlmin, tlmax, and binsiz specifiers determine the image binning
-dimensions:
-<PRE>
-  dim = (tlmax - tlmin)/binsiz     (floating point data)
-  dim = (tlmax - tlmin)/binsiz + 1 (integer data)
-</PRE>
-These tlmin, tlmax, and binsiz specifiers can be omitted if TLMIN,
-TLMAX, and TDBIN header parameters (respectively) are present in the
-FITS binary table header for the column in question.  Note that if
-only one parameter is specified, it is assumed to be tlmax, and tlmin
-defaults to 1. If two parameters are specified, they are assumed to be
-tlmin and tlmax.
-
-<P>
-<LI> Added "mask=transparent" support to the plist argument in
-FunTableRowGet(). If this string is passed in the call's plist
-argument, then all events are passed back to the user. This is useful
-when FunColumnSelect() specifies "$region" as a column in order to
-return the regionid value for each event.  In such a case, events
-found in a region have regionid >0, events passing the filter but not
-in a region have regionid == -1, events not passing the filter have
-regionid ==0.
-
-<P>
-<LI> Added FUN_WCS0 to the FUN_WCS option available to FunInfoGet().
-The original FUN_WCS option returns WCS Library handle (for use with
-Doug Mink's wcssubs library) suitable for use with images, regardless
-of whether the data are images or tables. For this structure, the WCS
-reference point (CRPIX) has been converted to image coordinates if the
-underlying file is a table (and therefore in physical coordinates). The
-new FUN_WCS0 structure has not had its WCS reference point converted
-to image coordinates. It therefore is useful when passing processing
-physical coordinates from a table.
-
-<P>
-<LI> Added -G switch to funcnts to print out floating point values
-with maximum %.14g precision.
-
-<P>
-<LI> Added -l switch to fundisp, which displays the pixels of an image as
-a list with X, Y, VAL columns.
-
-<P>
-<LI> Added support for images to funhist. The program will create
-a histogram of the values found in each pixel, or it can perform
-a projection over either axis.
-
-<P>
-<LI> All Funtools programs now accept "-" to mean "stdin" or "stdout",
-when the io mode is "r" or "w", respectively.
-
-<P>
-<LI> Changed behavior of the prec (precision) argument in FunParamPutd()
-(and the underlying fitsy routine ft_cardfmt()) so that if the double
-value being put is less than 0.1 or greater than or equal to
-10**(20-2-prec), then %20.[prec]e format is used, otherwise
-%20.[prec]f format is used.
-
-<P>
-<LI> Fixed behavior of "merge=replace" in FunColumnSelect() so that if
-tlmin/tlmax values are not specified in the replacing column, but are
-specified in the replaced column, then the original tlmin/tlmax values
-are used in the replacing column.
-
-<P>
-<LI> Improved funcnts error-handling when no valid region is specified.
-
-<P>
-<LI> Fixed region parsing of '#' comment character so that comments
-are terminated by new-lines, but not ';'. This is more intuitive behavior.
-
-<P>
-<LI> Fixed region parser so that a region (without parens), followed by
-a column expression (e.g., "circle 5 5 1,pha==4") is processed correctly.
-
-<P>
-<LI> Fixed funcnts so that the timecorr parameter specified by -t
-[timecorr] can be in lower case.
-
-<P>
-<LI> Fixed panda region shapes when processing a blocked image. The
-number of pies and number of annuli (args 5 and 8) were incorrectly
-being divided by the block factor (i.e., they were being treated as
-sizes).
-
-<P>
-<LI> Fixed bug in funcnts that resulted in slightly smaller
-integerized pixel boundaries being used when filtering events. This
-does not affect ordinary event filtering(in fundisp, funtable, etc.).
-In funcnts (which filters binary table events using image-style pixel
-filtering), this bug could result in fewer photons being counted than
-is the case when the equivalent image is used.
-
-<P>
-<LI> Fixed funcnts to work with raw event files on little-endian machines.
-
-<P>
-<LI> Fixed funhist so that it will read data from a pipe.
-
-<P>
-<LI> Fixed region parser (and funcnts) so that an include file ending
-with a comment stops the comment at the end of the include file.
-
-<P>
-<LI> Clarified the meaning of the "," operator (should it be "or" or
-"and") between a region and a non-region expression in a filter: if
-the second operand in the expression contains a region, the operator
-is "or", otherwise it is "and".
-
-<P>
-<LI> Fixed bug in funmerge, which was not handling integerization of
-negatively-valued physical pixels properly (not actually used in any
-known application).
-
-</UL>
-
-<H2>Beta release 1.0.b23 (02/16/01)</H2>
-<UL>
-<P>
-<LI> Fixed funcnts to report area correctly in arc-seconds.
-
-<P>
-<LI> Fixed funcnts to report radii correctly when summing.
-
-<P>
-<LI> Fixed bug in fundisp: a SEGV when trying to display an ASCII column
-from a binary table.
-
-</UL>
-
-<H2>Beta release 1.0.b22 (02/15/01)</H2>
-<UL>
-
-<P>
-<LI> Funcnts now will automatically output appropriate columns from
-the primary table in units of arc-seconds instead of pixels if WCS info
-is present. Use -p to force the output to be in pixels.
-
-<P>
-<LI> Added qualitative exposure correction to funcnts by means of the switch
-"-e source_exp[;background_exp]".  For each region, the average exposure is
-calculated and net counts (and background) are divided by the average
-exposure. See programs.html for more info.
-
-<P>
-<LI> Added qualitative time correction to funcnts by means of the switch
-"-t source_time[;background_time]". The net counts (and background) are
-divided by this time. See programs.html for more info.
-
-<P>
-<LI> Improved funcnts output. For example, column units are displayed
-(since surf_bri units now can be cnts/pix**2, cnts/arcsec**2, etc.)
-
-<P>
-<LI> Changed funcnts.gnuplot and funhist.gnuplot scripts to funcnts.plot
-and funhist.plot, respectively. The new scripts take an argument
-such as "gnuplot" or "ds9" and output data appropriate for each
-target. Also enhanced funcnts.plot so that it senses the axis units
-automatically.
-
-<P>
-<LI> Fixed bug in funcnts when handling regions whose centers are out of the
-image. Processing often resulted in BUS ERROR or zero counts, and it took
-forever to reach those results
-
-<P>
-<LI> Fixed bug in FunImagePut() when outputting float data on
-little-endian machines (PCs/Dec Alpha) -- an erroneous error was
-signaled trying to convert from native to IEEE before writing.
-
-<P>
-<LI> Fixed bug in fundisp when displaying the mask of a double/float
-image using the mask=all option.
-
-<P>
-<LI> Fixed bug in fitsy/headimage/ft_imageloadhead(fits), in which the
-default value for LTV[1,2] was incorrectly set to 1.0, not 0.0. This
-means that region physical coordinates applied to FITS images and
-arrays that did not have LTM/LTV keywords were 1 pixel off.
-
-<P>
-<LI> Fixed obscure bug in region circle processing when a block factor
-is specified in the section command but the circle has radius less
-than the block.
-
-<P>
-<LI> Fixed bug in FunImageGet which was returning the full image in
-cases where a region was specified but no image pixels were in the
-region.  An empty image is now returned.
-</UL>
-
-<H2>Beta release 1.0.b21 (02/01/01)</H2>
-<UL>
-
-<P>
-<LI> In funcnts, added ability to specify a separate background file.
-When using a separate background file, the background area will be
-normalized by the ration of the pixel sizes of the two files, if
-requisite WCS info is available.
-
-<P>
-<LI> In funcnts, added -r switch to output radii (and angle)
-information. This is useful with annulus and panda shapes when
-plotting radial profiles.  An example plot script, funcnts.gnuplot, is
-available for use with gnuplot  (3.7 and higher):
-<PRE>
-  funcnts ... | funcnts.gnuplot
-</PRE>
-
-<P>
-<LI> First version of the funhist program, which creates a 1D
-histogram by binning the specified column in a binary table. The
-tabular output can be plotted using funhist.gnuplot:
-<PRE>
-  funhist snr.ev x | funhist.gnuplot
-</PRE>
-
-<P>
-<LI> Added additional error messages to funcnts when invalid binning
-parameters are found for one or more binary table binning columns.
-
-<P>
-<LI> Fixed bug in FunImagePut() which sometimes occurred when
-dimensions were passed in the calling sequence. If, in addition, a
-reference handle was passed in the FunOpen() call, then the output
-dimensions are erroneously taken from the reference file, not the
-passed dimensions.
-
-<P>
-<LI> Fixed bug in filter lex code (filt.l) in which yyrestart was
-being called incorrectly with the string to be parsed as the argument
-(should be NULL).
-
-<P>
-<LI> Fixed bug in filter code in which the Sun cc compiler was creating
-a useless .o file in the working directory.
-
-<P>
-<LI> Fixed bug in region parser which made it impossible to specify
-angles with a 'd' or 'r' suffix unless WCS info was in the file. (The
-use of 'd' or 'r' with angle is independent of WCS but the check was
-there anyway.)
-
-</UL>
-
-<H2>Beta release 1.0.b20 (11/29/00)</H2>
-<UL>
-
-<P>
-<LI> Fixed a serious bug in which exclude regions were being ignored 
-when multiple annuli were specified. That is, in a region specification
-such as:
-<PRE>
-  annulus 512 512 0 100 n=4; -circle 510 510 20
-</PRE>
-or
-<PRE>
-  annulus 512 512 0 25 50 75 100; -circle 510 510 20
-</PRE>
-the excluded region was not being sensed properly. Note that
-single regions did work properly with exclude regions.
-
-<P>
-<LI> Optimized funcnts so that the time for processing an event list
-(binary table) is no longer proportional to the number of pixels in
-the image. The unoptimized code was taking forever with Chandra ACIS
-images (8192**2 pixels), even with relatively few events.
-
-<P>
-<LI> Fixed bugs that gave incorrect answers when image regions were
-combined with image sections.
-
-<P>
-<LI> Fixed bug in parsing image section of the form: "foo.fits[*,6:9,2]",
-i.e. the default ("*") x dimensions, followed by specified y dimensions.
-
-<P>
-<LI> Added -g option to funcnts to change some output formats from
-12.3f to 12.3g to accommodate display of very small numbers.
-</UL>
-
-<H2>Beta release 1.0.b19 (11/21/00)</H2>
-<UL>
-<P>
-<LI> Fixed bug in filter code that caused a SEGV on Solaris machines
-when the first specified spatial region is an exclude region. Our
-user-supplied qsort/compare algorithm was confusing the Solaris qsort()
-routine, causing it to SEGV by trying to process a record prior to the
-beginning of the passed array of records.
-</UL>
-
-<H2>Beta release 1.0.b18 (11/13/00)</H2>
-<UL>
-<P>
-<LI> Fixed bug in handling bitpix=-32 (single float) images.
-
-<P>
-<LI> Fixed gio gskip routine to better handle skip of 0 bytes.
-</UL>
-
-<H2>Beta release 1.0.b17 (11/10/00)</H2>
-<UL>
-
-<P>
-<LI> Fixed working of $REGION keyword in funtable.
-
-<P>
-<LI> Removed FunFlush() from end of funtable (it was redundant).
-
-<P>
-<LI> Fixed bug in gopen() handling of "pipe:".
-
-<P>
-<LI> Fixed bug in gseek() where pipes, streams, and sockets were
-not skipping bytes properly (that can do skips, but cannot do other
-sorts of seek).
-
-</UL>
-
-<H2>Beta release 1.0.b16 (10/23/00)</H2>
-<UL>
-
-<P>
-<LI> Added -s switch to funcnts to support display of summed results 
-(as well as individual results for each region), i.e. each row in the
-summed bkgd-subtracted table contains the sum of counts and areas from
-previous rows.
-
-<P>
-<LI> Added -f [format] switch to fundisp to allow control over the
-display format for each data type.
-
-<P>
-<LI> Fixed bug in which regions could be incorrectly re-ordered.  This
-was a problem with annular ellipses and rectangles created by ds9 and
-then used in funcnts (the only program where the order of the regions is
-important).
-</UL>
-
-<H2>Beta release 1.0.b15 (10/11/00)</H2>
-<UL>
-
-<P>
-<LI> Changed the names of routines FunEventsGet() and FunEventsPut()
-to FunTableRowGet() and FunTableRowPut(), respectively.  The old names
-are still valid (using #define in funtools.h), so no code change is
-required.
-
-<P>
-<LI> Changed funevents program name to funtable, in line with API changes.
-
-<P>
-<LI> Renamed FunInfoGet/Put() parameter FUN_EVSIZE to FUN_ROWSIZE, in
-order to reflect change from use of "events" to use of "row" in
-funtools binary table support. The old name is still supported as
-an alias.
-
-<P>
-<LI> Completed first version of funmerge program to merge FITS binary tables.
-
-<P>
-<LI> Fixed bug in line region shape that was causing a SEGV with event data.
-
-<P>
-<LI> Fixed minor compiler warnings using "gcc-Wall".
-
-<P>
-<LI> Added the ability for FunOpen() to open a list of event files and
-read events from this list synchronously or asynchronously. This
-facility is part of an experimental set of parallel processing
-techniques that are being added to funtools.  Documentation will be
-forthcoming when we know which techniques have value!
-</UL>
-
-<H2>Beta release 1.0.b14 (9/22/00)</H2>
-<UL>
-
-<P>
-<LI> Added first version of funmerge program to merge FITS binary tables.
-
-<P>
-<LI> Changed the output format of funcnts so that the main results
-(background-subtracted table) are displayed first. This means that the
-result columns always start at line 4 in the file (after a 1-line
-comment and a 2-line header) and end at the first blank line. The
-fixed format makes it easier for programs such as sed to extract
-results for further processing. For example:
-
-<PRE>
- csh> cat fun.sed
- 1,/---- .*/d
- /^$/,$d
-
- csh> funcnts snr.ev[pha==1] "annulus 512 512 0 200 n=8" | sed -f fun.sed

-
-<P>
-<LI> Fixed bug in row# processing in which all range was ignored if
-lo range value was 1 (e.g., row#=1:7).
-
-<P>
-<LI> Fixed bug in event header processing in which the multiple
-instances of keywords HISTORY, COMMENT, and CONTINUE were not all
-being copied from the old to the new header (e.g. in funevents).
-
-<P>
-<LI> Fixed processing of ARRAY() and EVENTS() specifiers in FunOpen().
-
-<P>
-<LI> Fixed 'make clean' directive so that it also cleans funtools subdirs.
-</UL>
-
-<H2>Beta release 1.0.b12 (9/5/00)</H2>
-<UL>
-
-<P>
-<LI> Improved the performance of panda regions so that the funcnts
-"wall time" now is proportional to the size of the panda region, not
-the size of the image. (The latter is the case with the pie shape; use
-of panda is recommended over pie.) This means that it is possible to
-run funcnts on an ACIS file at zoom 1 (8192x8192) in seconds rather
-than (tens of) minutes.
-
-<P>
-<LI> Added support for INET sockets to gio and hence, to funtools.
-This means that you can read/write from/to sockets on other machines,
-creating a distributed pipeline. For example:
-<PRE>
-  on m1:  funevents foo.ev m2:1428
-  on m2:  funevents :1428 m3:1428
-  on m3:  funevents :1428 ...
-</PRE>
-etc. Tests indicate that this is faster than pipes on a single
-machine, once the CPU is saturated on that machine. (But note that it
-is not faster until the CPU is saturated, due to the efficiency of
-Unix pipes and the I/O wait time on non-saturated CPUs.) This new
-facility implements the parallel processing technique called "process
-decomposition" for pipelines, in which a pipeline process is run on
-several machines at once, with different machines handling separate
-parts of the pipeline process.
-<P>
-NB: socket support requires that the libraries:
-<PRE>
-  -lsocket  -lnsl
-</PRE>
-be added to the Solaris link line.
-
-<P>
-<LI> Added support for the row#=lo:hi keyword to process specific rows
-in a FITS binary table. For example:
-<PRE>
-  funevents "test.ev[row#=3:8]" stdout ...
-or
-  funevents "test.ev[row#=(3,8)]" stdout ...
-</PRE>
-will only process rows 3 to 8 (inclusive) of the test.ev file. Along
-with image section specification, use of the row#= keyword implements
-the parallel processing technique called "data decomposition", in
-which several copies of a single program operate on different parts of
-a single data file.
-
-<P>
-<LI> Added guard code to image region processing to catch illegal event
-values.
-
-<P>
-<LI> Fixed bug when writing FITS image extensions in which dim1, dim2,
-and bitpix were being output as 0.
-
-<P>
-<LI> reversed the y row order of displayed images in fundisp, so that pixel
-(1,1) is in the lower left corner, as is the case for ds9 image display.
-</UL>
-
-<H2>Beta release 1.0.b11 (8/10/00)</H2>
-<UL>
-
-<P>
-<LI> Fixed annulus accelerators and panda regions -- again.  Old
-problems (from the original implementation) were uncovered related to
-the use of these shapes in boolean expressions. Documented an old
-restriction that panda and accelerators must be put last in a boolean
-expression and added code to signal an error if they are not placed last.
-
-<P>
-<LI> The behavior of the point shape was changed so that multiple x,y
-pairs in a single shape specifier now are assigned different region
-ids. This makes the behavior of points and annuli consistent with one
-another.
-</UL>
-
-<H2>Beta release 1.0.b10 (8/08/00)</H2>
-<UL>
-
-<P>
-<LI> Fixed annulus accelerators and panda regions.  These were
-broken when dynamic loading was implemented.
-
-<P>
-<LI> Fixed a bug in the event filter body code (i.e., the basis for
-the slave filter program). Reading the data sometimes incorrectly
-calculated the number of events being passed -- which only showed up
-occasionally on the Alpha!
-</UL>
-
-<H2>Beta release 1.0.b9 (8/03/00)</H2>
-<UL>
-<P>
-<LI> Removed compilation of some extraneous routines from wcs library.
-Also renamed wcssubs directory to wcs.
-
-<P>
-<LI> Added calls to hlength() before wcsinit(). This is necessary in
-ds9 (and is a safeguard in other programs) because once hlength() is
-called before any invocation of wcsinit(), it must always be used.
-
-<P>
-<LI> Fixed bug in filter code in which CTYPE1 and CTYPE2 param values
-were not being passed to wcsinit() as valid FITS strings: the single
-quotes were missing.
-
-<P>
-<LI> Fixed a bug in fitsy in which the card buffer was not being
-null-terminated properly when a "card insert" call reallocated space
-for more cards.
-
-<P>
-<LI> Added protective code so that one cannot set FILTER_PTYPE to
-"dynamic" if dynamic filter objects are not available.
-
-<P>
-<LI> Ported to Debian Linux, which (believe it or not) required
-removal of extraneous strdup() and strstr() declarations in the code
-(apparently these are macros in that version of Debian gcc, so you
-cannot declare them).
-</UL>
-
-<H2>Beta release 1.0.b8 (8/01/00)</H2>
-<UL>
-
-<P>
-<LI> Added new filter ptype ("contained"), which builds a separate
-process by compiling both the main routine and the region code.  This
-is different from the "process" ptype, which compiles the main
-routine, but links in pre-compiled region code (in order to make the
-program build more quickly).  It is needed by ds9 so that the latter
-does not have to keep track of the compiled region code module.
-</UL>
-
-<H2>Beta release 1.0.b7 (7/25/00)</H2>
-<UL>
-
-<P>
-<LI> Changed filter code so that, in simple cases, we can access the
-contents of a file. This is needed so that funcnts can work properly in one
-oft-used case, i.e., if the file foo contains:
-<PRE>
-  circle 5 5 1
-  circle 4 4 1
-</PRE>
-then:
-<PRE>
-  funcnts foo.fits @foo
-</PRE>
-now will display the 2 regions in its output, instead of displaying the
-near useless "@foo". This only works for simple cases where only a file 
-is input, not in odd combinations like:
-<PRE>
-  funcnts foo.fits "@foo,circle 1 1 1"
-</PRE>
-
-<P>
-<LI> Added programming tutorial and enhanced the programming
-reference documentation.
-
-<P>
-<LI> Ported to Windows via the Cygwin environment from
-RedHat.  We tested on an NT box, which has decent multi-tasking
-support. Whether it works on Windows95 is unknown.
-
-<P>
-<LI> Upgraded WCS libraries to 2.8.3.
-
-<P>
-<LI> Ported to new and strict SGI C compiler, which uncovered
-lots of unused variables, etc.
-
-<P>
-<LI> Fixed FunParamPut status return.
-</UL>
-
-<H2>Beta release 1.0.b6 (7/15/00)</H2>
-<UL>
-
-<P>
-<LI> Ran Purify with each high level program and each funtest
-program.
-<P>
-<LI> Changed behavior of merge=update option of
-FunColumnSelect() so that the update of the user column value only
-takes place if the user mode has "w" in it.  Previously, merge=update
-overrode the mode flag and always updated the user value.  Note that
-all calls to FunColumnSelect with merge=update must change "r" to "rw"
-in order to have that user column merged. (The merge=replace already
-was checking the mode flag -- the fact that they were doing different
-things is a bug.)
-<P>
-<LI> Added ability to FunOpen extensions by HDU name. (I
-thought I had already done this!)
-<P>
-<LI> Fixed bug that was adding a NULL table at the end of
-most binary table files (i.e., those that were not copying the rest of
-the input file).
-<P>
-<LI> Re-ported to Alpha. The problem found most often was the
-casting of pointers to ints when doing pointer calculations, i.e.:
-<PRE>
-  char *s, *t;
-  n = ((int)s - (int)t);
-</PRE>
-which is invalid on the 64-bit Alpha. Instead use:
-<PRE>
-  char *s, *t;
-  n = (s - t);
-</PRE>
-Also broadened the check for use of dlopen in configure to match Alpha's
-library configurations (On Alpha, dlopen is in libc).
-
-<P>
-<LI> Changed FunColumnActivate() so that funtools will
-process columns in the sorted order specified by that routine. Thus:
-<PRE>
-  fundisp foo.ev "time y x"
-</PRE>
-will display columns in that order. 
-
-<P>
-Sorting does not take place if the activate list contains only exclude
-columns (since there is nothing to sort). Also, you can turn off
-sorting altogether (mimicking the old behavior) by calling
-FunColumnActivate() with a "sort=false" in the plist argument:
-<PRE>
-  FunColumnActivate(fun, "y x", "sort=false");
-</PRE>
-or by adding "sort=false" to the activate string itself:
-<PRE>
-  # by default, its sorted
-  fundisp $E "time y x"
-               TIME       Y       X
-   ---------------- ------- -------
-             6.8500      -7      -7
-             6.8600      -7      -7
-</PRE>
-while:
-<PRE>
-  # turn off sorting
-  ./fundisp $E "time y x sort=false"
-         X       Y             TIME
-   ------- ------- ----------------
-        -7      -7           6.8500
-        -7      -7           6.8600
-        -7      -7           6.8700
-</PRE>
-</UL>
-
-<H2>Beta release 1.0.b5 (7/8/00)</H2>
-<UL>
-
-<P>
-<LI> Changed all FunParamSet calls to FunParamPut, to make the
-naming consistent with FunImagePut, FunEventsPut, etc.
-
-<P>
-<LI> Fixed bugs preventing tlmin/tlmax from being changed by the
-user in binary tables. Also tlmin/tlmax are now written out using a
-data type that matches the data type of the respective column.
-
-<P>
-<LI> Extended filter syntax to allow "," as separator between
-filename and filters (as well as brackets), i.e.:
-<PRE>
-  foo.fits,events  # event extension
-  foo.fits,pha==1  # filter on default extension
-  foo.fits,1       # first extension
-</PRE>
-Note that all but simple expressions will need to be quoted because
-of the shell:
-<PRE>
-  foo.fits,pha==1&&pi==2  # & tells shell to run in bkgd
-  foo.fits,pha==1||pi==2  # similar problems with pipes
-  foo.fits,circle(1,2,3)  # parens are grabbed by shell
-</PRE>
-
-<P>
-<LI> Fixed configure so that --with-lib is no longer necessary
-to generate a single funtools.a library. Removed this argument from
-saoconfig. Note that:
-<PRE>
-  ./configure
-</PRE>
-
-now works properly again, so saoconfig should not be used.
-
-<P>
-<LI> Changed FunFlush() mode argument (single characters) to a
-plist argument (keyword arguments). In particular,
-<PRE>
-  FunFlush(fun, "C");
-</PRE>
-is now:
-<PRE>
-  FunFlush(fun, "copy=remaining");
-(or FunFlush(fun, "copy=remainder"); )
-</PRE>
-
-This syntax extension allows FunFlush to support the copy of the
-extension associated with the reference handle, which allows one to
-copy any extension from an input file to an output file:
-<PRE>
-  /* open a new input extension */
-  ifun = FunOpen(...);
-  /* make this new extension the output reference extension */
-  FunInfoPut(ofun, FUN_IFUN, &ifun, 0);
-  /* copy the current reference extension to output */
-  FunFlush(ofun, "copy=reference");
-</PRE>
-
-<P>
-<LI> Fixed bugs in region parser that caused pure floating
-point positions (i.e., numbers w/o format characters) always to be
-interpreted as pixels.  Also fixed galactic and ecliptic conversions.
