+ Other revisions:
+
+ * Allow symbolic constants in expressions for QUADPACK functions

+
+ * Plotting functions recognize lambda expressions as functions
+ to plot
+
+ * QUADPACK functions recognize lambda expressions and function
+ names as integrands

+
+ * Regenerate SLATEC numerical code from Fortran
+
+ * Regularize use of intermediate expression (%t) labels
+
+ * Renamed files in some add-on packages so that package name
+ coincides with file name (grobner, sarag, linearalgebra,
+ zeilberger)
+
+ * Renamed functions "mod" to "polymod" and "nummod" to "mod"
+
+ * Renamed "interpolate" (one-dimensional numerical root finder)
+ to "find_root"
