+Copies files from one directory to another with possible
+transformations.
+
+Files named FILE.spp will be transformed via the spp preprocessor
+subject to environment definitions.  Source FILE.copyimgspp results in
+destination file FILE in the corresponding destination directory.
+
+Files named FILE.copyimgsh are run as shell scripts in (i.e. via chdir)
+the corresponding destination directory (and not copied).
+
+First regular files are copied.  Then transformations are preformed.
+Finally, shell scripts are run.
