For those unfamiliar with Perl and Perl modules, the way to install "transfer"
is to:

1. Type "perl -V" and check the values stored in @INC, which will be listed
   at the end of the output.  The array @INC holds the locations that perl
   looks for modules.  The string "." indicates that perl will also look
   in your current directory at execution time.

2. Move the module Transfer.pm to a location listed in @INC.
   If you do not have write permission on any of the directories other than
   ".", you will have to keep "transfer" and Transfer.pm in the same directory
   and perform all of your transfers from there.

3. Make sure that the first line in "transfer" points to the location of
   perl on your system.  You can find this location by typing "which perl".
