 User-defined spectra.
 
+Argument -c introduced to most of the subjob calls, which allows the user to
+choose his own job catalog by setting job_catalog in the configuration file
+(default is ~/job_queue). Workaround for mpixec with -env option.
+Adjustments for lcxt4 (Bergen Center for Computational Science) (mrun, subjob)

+Transpositions for the 2D domain decomposition have been optimized by using
+f_inv as an automatic array instead of providing the memory by a dummy argument.
+This spares one copy loop per transposition. Order of indices in the 3D loops
+in some of the transpose routines have been rearranged for better cache utilization.
+Both have been suggested by Roland Richter (SGI) as part of the
+HLRN-II benchmark process. (transpose)
+
+Workaround for getting information about the coupling mode. (palm)
