- * Cp copies source files to target files.
- * 
- * The global PATH_T structure "to" always contains the path to the
- * current target file.  Since fts(3) does not change directories,
- * this path can be either absolute or dot-relative.
- * 
- * The basic algorithm is to initialize "to" and use fts(3) to traverse
- * the file hierarchy rooted in the argument list.  A trivial case is the
- * case of 'cp file1 file2'.  The more interesting case is the case of
- * 'cp file1 file2 ... fileN dir' where the hierarchy is traversed and the
- * path (relative to the root of the traversal) is appended to dir (stored
- * in "to") to form the final target path.
