Description:
------------
copylink

    reads the filename linked to by the argument and replaced the link with a copy of the file. It opens a filehandle to read from the link, deletes the link, and then copies the filehandle back to the link.
safecopylink

    does the same as copylink but without the open-and-delete manouvre. Instead, it uses File::Spec::Link to find the target of the link and copies from there.

This module is mostly a wrapper round File::Spec::Link::linked and File::Copy::copy, the functionality is available in a command line script copylink.
EXPORT

Nothing by default, can export copylink, `safecopylink.

Test script:
---------------
File::Copy::rmscopy

Expected result:
----------------
 copy("file1", "tmp");        # creates the file 'tmp' in the current directory
  copy("file1", ":tmp:");      # creates :tmp:file1
  copy("file1", ":tmp");       # same as above
  copy("file1", "tmp");        # same as above, if 'tmp' is a directory (but don't do
                               # that, since it may cause confusion, see example #1)
  copy("file1", "tmp:file1");  # error, since 'tmp:' is not a volume
  copy("file1", ":tmp:file1"); # ok, partial path
  copy("file1", "DataHD:");    # creates DataHD:file1

  move("MacintoshHD:fileA", "DataHD:fileB"); # moves (doesn't copy) files from one
                                             # volume to another

Actual result:
--------------
 copy("file1", "tmp");        # creates the file 'tmp' in the current directory
  copy("file1", ":tmp:");      # creates :tmp:file1
  copy("file1", ":tmp");       # same as above
  copy("file1", "tmp");        # same as above, if 'tmp' is a directory (but don't do
                               # that, since it may cause confusion, see example #1)
  copy("file1", "tmp:file1");  # error, since 'tmp:' is not a volume
  copy("file1", ":tmp:file1"); # ok, partial path
  copy("file1", "DataHD:");    # creates DataHD:file1

  move("MacintoshHD:fileA", "DataHD:fileB"); # moves (doesn't copy) files from one
                                             # volume to another
