+
+* Fri Jan 11 2008  Brad Bell <bradbell at seanet dot com> 20071229-5
+- Remove introduction/exp_apx/exp_apx from the set of tests 
+- (which should have been done in 20071229-4). 
+- From now on test building rpm locally before making tags.
+
+* Thu Jan 10 2008  Brad Bell <bradbell at seanet dot com> 20071229-4
+- Add code to print out DBL_EPSILON at the beginning of the example tests.
+- Remove --with-Introduction (it only checks by hand calculations that are in 
+- AD Introduction section of the documentation). 
+- Remove extra --with-Documentation
