Version 1.4.0
 5Feb18 * Bumped version of dstester from 1.0.0 to 1.4.0 to agree with
	  the rest of the updated testers.
 8Feb18 * Renamed various words in dstester in the style of the other
	  testers, also in dstester-test.
	* Bumped version of dstester-test from 1.0.0 to 1.4.0.
	* Removed TTESTER DISPLAY 1.0.3 section from dstester-test and
	  revised to work with tester-display 1.4.0.
	* Removed FPNOSTACK logic, so fp stack must be separated.
	* Revised load order so VERBOSE and host words are defined early.
 9Feb18 * Revised user interface commentary in dtester.fs, and did
	  various renamings.	
10Feb18 * Added $DROPS and $= to dstester-test.fs, gone from dstester.fs.
11Feb18 * Revised array handling in dstester.fs to conform with deepest
	  error first treatment in other testers.
	* Added DCELL words to dstester.fs.  
	* Increased string buffer from 28 to 40 cells for 32 bits to get

Version 1.0.0
21Aug10 * Revised to call ttester.fs.
	* Changed license from LGPL to Public Domain.
	* Added starts and results arrays.
22Aug10 * Added forbidding of initial frames, saving and
	  comparing the frame stack, zeroing it after each stage
23Aug10	* Started dstester-test.fs, based on
	  otester-test.fs 0.6.0.
25Aug10 * Added independent error reporting, because we want it
	  decoupled from stack emptying, so we can't just use
	  the ttester error vector when dstester is combined
	  with ttester.
27Aug10 * Finished tests.
28Aug10 * Revised dstester-test.fs to use explicit composition
	  of dstester and ttester.
 6Sep10 * Started revision to incorporate the simplifying idea
	  of ttester-xf, saving and restoring the initial string
	  stack, so clobbering by results or goals is impossible.
	* Uglified names.
 7Sep10 * More name changes.
 	* Finished.
 8Sep10 * Tested with pfe and gforth, with dstrings-ext and
	  without, with ttester and ttester-xf.

	  dstester-test.fs.
