- added with-output-to-load-script(*) and write-to-load-script 

functions, which provide support for creating the package-loading
  script,
- added a code template to load libtool's ".la" files, stolen from
  scsh-yp (by Eric Knauel),
- added "--verbose" option,
- preserve permissions of copied files/directories, and use a
  function to obtain permissions for new directories.
