;;; Compiles all .sls files that lie within the directory (and
;;; its subdirectories) from which this Scheme script is invoked.
;;;
;;; Compiling a large number of interdependent source files by
;;; hand is inconvenient because files must be compiled in an
;;; order consistent with their import dependencies:  Every
;;; compiled library must be compiled before any compiled
;;; files that import the library.
;;;
;;; If the files compiled by this script define libraries
;;; that are imported by compiled files that lie outside the
;;; directory from which this Scheme script is invoked, then
;;; those compiled files will become stale, which means those
;;; compiled files should be removed or replaced by freshly
;;; compiled files.
;;;
;;; Larceny refuses to execute compiled code from a stale
;;; file, because the compiled code in stale files may be
;;; dangerously inconsistent with the compiled code of
;;; libraries on which the stale file depends.
