+2.0.0-b4 - 7/11/00
+   Fixed compiler warnings at -Wall level
+   Began work on CTSim program to be graphical front-end of all functions
+   Moved current src/*.cpp to tools/*.cpp
+   Made CTSim graphical front-end's home to be src/
+	
+2.0.0-b3 - 7/10/00
+   Added highly optimized backprojection method idiff3
+   Moved comparative stats to if-2 program from ifinfo
+   Fixed image display in if2img using G2 library
+   Added column-plot and row-plot options to if-2
+   Added autoselection of analytic/calculated spatial responses to SignalFilter
+   Added frequency-based preinterpolation to SignalFilter and idiff3
+	backprojection method. Currently, this technique is still under
+	development and debugging
+   Moved graphic file writing to ImageFile class from if2img program
+
+2.0.0-b2 - 7/07/00  
+   Cleaned up SignalFilter class
+   Added zeropad option to pjrec
+   Added zeropad options to html and cgi files
+   Added fourier_table and rfttw filter methods
+   Added FFTW routines to use real/half-complex transformations
+	
+2.0.0-b1 - 7/05/00
+   Updated trace level processing
+   Added trace level to SignalFilter
+   Fixed magnitude vs. real output bug in FFT/Fourier filter
+	
+1.9.9 - 7/04/00
+   Fixed const issue with ImageFileArray
+   Fixed Array2dFile::labelsCopy()
+   Added copy constructor and assignment for Array2dFileLabel class
+   Added Timer to if-2.cpp and ifinfo.cpp
+   Added beginning of frequency-based (DFT & FFT) filter to SignalFilter
+   Added option processing for filter-method for pjrec to choose
+	between convolution, dft, & fft filtering
+   Fixed format string for EZPlot so axis labels now print
+   Added support for FFTW library
+	
+1.9.8 - 6/27/2000
+   Rewrote Array2dFile class to be non-templated
+   Rewrote Array2dFile class to make reads and writes atomic. No disk files are kept open.
+   Rewrote Array2dFileLabel class to make members private, added access routines
+   Removed timedate.cpp in favor of standard C library time/date functions
+   Renamed ctrec to pjrec, sample-ctrec.sh to sample-ctsim
+   Added signature tag and creation date/time to projection files
+	
+1.9.7 - 6/25/2000
+   Standardized string option processing by classes. All classes use character strings
+	to select options rather than numeric constants. Added fail() and failMessage()
+	methods to verify that objects are created correctly by character strings.
+   Hid C++ assignment and copy constructors in classes that should not have assignment/copy
+   Rewrote ImageFile class
+   Started support for dmallocxx library, not finished
+   Added G.T. Herman image comparision statistics to ifinfo (see imagefile.cpp)
+   Updated ifinfo to show comparative statistics
+   Added printLabels() to Array2dFile class
+   Added printStatistics() to ImageFile class
+	
+1.9.6 - 6/22/2000
+   Moved conversion filter name/id to Filter class
+   Moved conversion backprojection name/id to Backproj class
+   Added MPI broadcasting of strings
+	
+1.9.5 - 6/21/2000
+   Merged proj_reconstr into class Projections
+   Used auto_ptr in Projections::reconstruct to make sure destructor is always called
+   Code cleanup in projections.cpp
+   Moved conversion of phantom names/id to Phantom class
+   	
+1.9.4 - 6/20/2000
+   Converted projection files to C++ library with frnetorderstream
+   Converted image files to C++ library with frnetorderstream
+   Converted filter and convolution to object-oriented code
+   Changed default image file to float from double -- Changable in imagefile.h
+   Optimized image file writing on little-endian architectures
+   Updated README and INSTALL
+	
+1.9.3 - 6/19/2000
