+Wrote rxpiece tool that will render pictures using tiling and
+can handle different output formats and hyperspectral pictures.

+Only runs on a single machine, however -- no NFS locking on
+shared volumes.  Mainly a demonstration tool for RpictSimulManager
+C++ class, but may have its uses.
+Taoning added genssky -L option to specify global and diffuse
+illuminance values for output calibration.
-+
-+
+Created C++ class for rcontrib and example tool rxcontrib, which
-+
+is an optional compile in the src/rt directory.  The output
-+
+model is more general in some respects and the operations more
-+
+efficient, but standard output is not supported, nor is ASCII
-+
+results data.
-+
-+
+Added strnstr.c compatibility module in ray/src/common, since
-+
+it isn't present on Linux derivatives.
-+
-+
+Added WGMDfunc material type with programmable roughness and
-+
+separate modifier paths for the different components.
-+
-+
+Added gensurf -i option at the request of Peter Apian-Bennewitz
-+
+to reverse surface normals, mostly for data input, when it is
-+
+a bit more difficult to adjust.
-+
-+
+Added rad -N option to rholo call for multiprocessing when
-+
+mkillum and/or mkpmap are involved in octree prep.
-+
-+
+Added ability of gendaymtx to read EPW as well as WEA files.
-+
+When EPW input is provided, the 3-hour average dew point is
-+
+used to compute a more accurate precipitable water content
-+
+value.  It currently does not use these data directly from
-+
+the EPW input, relying instead on a dew-point-to-W calculation.
-+
+This follows the request and recommendations of David G-M.
-+
-+
+Removed limitation in rfluxmtx, which was disallowing distant
-+
+and local receivers. Found this to be a perfectly valid approach
-+
+for some annual daylighting scenarios.
-+
-+
+Wrote new pvsum tool to handle cases dctimestep can't, like
-+
+spectral input pictures.  It also adds a -N option for multi-
-+
+processing on Unix machines, which utilizes memory-mapped
-+
+inputs for efficient i/o sharing.
-+
-+
+Made it so genBSDF can use spectral rendering for a
-+
+more accurate photometric result.
-+
-+
+Changed default matrix representation to float rather than
-+
+double, which uses less RAM and supports faster operations
-+
+in general.  Build with compiler flag:
-+
+        -DDTnativeDTrmx_native=DTdouble
-+
+to get back higher precision representation.
-+
-+
+Taoning Wang updated genssky and gensdaymtx to provide illuminance
-+
+calibration and accept EPW files directly as input.
-+
-+
+Added -e expr and -f file.cal options to all rendering tools, not
-+
+just rcontrib/rxcontrib.  Feature request from Peter A-B.
-+
-+
+Fixed slight bias in indirect calculation caused by ambient
-+
+collision detection, pointed out by Jon Sargent.  New code
-+
+keeps track of rejected samples and sells them back to
-+
+later calls to get something closer to a true Poisson
-+
+sampling method.
-+
-+
+Altered rvu "origin" command to take shift amounts forward,
-+
+right, and up rather than taking an explicit origin, which
-+
+can be done easily enough with the "view" command.  Peter A-B
-+
+requested (sort of).
-+
-+
+Added genglaze tool created by Taoning Wang to generate
-+
+spectral glazing materials based on CGDB data and models.
-+
-+
+Fixed bug that caused inf and nan errors with -cw setting
-+
+where longer wavelength was substantially less than limits
-+
+of specified spectra.
-+
-+
+Created bsdfpeaks utility to identify and report full-width,
-+
+half-maximum sizes of peaks in SIR and XML inputs.
-+
-+
+Changed default super-sampling in bsdf2ttree from 256 to 64,
-+
+since there doesn't seem to be much benefit to the higher
-+
+sampling rate for most BSDFs.
-+
-+
+Fixed problem with "mirror" primitive, which was not permitting
-+
+indirect rays to transmit through alternate material type.
-+
+Thanks to Jon Sargent for finding problem and help resolving it.
-+
-+
+Added experimental C++ based rxpiece tool to default installation.
