- * --------------------------------- ~~~~~~~~~~~~~~~~
- * foreach() - Calls a function for each of the file names given.
- * Patterns are expanded to the matching file names.
- * Directories and soft links are ignored.
- * The user supplied function is called with the full
- * path name of each matched file. This may lead to
- * unexpected results if two or more available volumes
- * have the same name. The canonical way to do it, is to
- * pass a lock on the directory containing the file and
- * have the function temporarily CurrentDir() to it.
- * Alas, doing that will require a rewrite of almost the
- * entire package so we will just have to live with it
- * for now. Maybe in a future release... ;-)
