+
+    Refined INSTALL text; added 'showconfig' target.
+

+commit 26cb659dd79636489db5a051aa60fff80273a7b9
+Author: Field G. Van Zee <field@cs.utexas.edu>
+Date:   Thu Dec 6 15:34:53 2012 -0600
+
+    Added auto-detection of version string (via git).
+    
+    Details:
+    - Added build/update-version-file.sh script for auto-detecting "version"
+      string and updating 'version' file accordingly. (If .git directory is
+      not present, then it is assumed this copy of BLIS is a downloaded
+      release, in which case 'version' file is left unchanged.)
+    - Added invocation of update-version-file.sh to configure script.
