910            * R/sparseMatrix.R: apply the above
911    
912            * R/Csparse.R: coercion Csparse* to dense* now preserves shape properties.
913    
914            * src/Mutils.h (mMatrix_as_geMatrix): new, based on
915            * src/Mutils.c (dup_mMatrix_as_geMatrix): new; generalization of

920            * R/denseMatrix.R (.dense2C): based on dense_to_Csparse: name it,

954    
955            * R/Ops.R ("Arith" etc): move almost all "Ops" methods to new R
956            file; start using "Logic", hence
957    
958            * DESCRIPTION (Depends): R >= 2.4.1 (since we want "Logic")
959            * NAMESPACE: import and export "Logic"
