$0 FROM-DIR TO-DIR ENVIRONMENT

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.
