+The following are the changes from calc version 2.15.0.7 to 2.15.1.0:
+
+    Converted all ASCII tabs to ASCII spaces using a 8 character
+    tab stop, for all files, except for all Makefiles (plus rpm.mk).
+    The command `git diff -w` reports no changes.  There is no
+    functionality change in calc: only ASCII tabs to ASCII spaces.
+
+    Fixed trailblank.  It was pruning . in its find search.
+    Added check for ASCII tabs is non-Makefiles.

+    This version will form the basis for the calc v2 to calc v3 fork.
