The `convert_links.cl' script converts all the symbolic links in a
given directory from absolute to relative.  Relative links can be more
convenient, since them and the files they point to can be more easily
moved, without having to recreate the symbolic links to moved files.

For example, consider this setup:

crikey% ls -Ral
.:
total 32
drwxr-xr-x    4 layer    fi           4096 Jan 22 14:22 ./
drwxr-xr-x    5 layer    fi           4096 Dec  9 09:52 ../
drwxr-xr-x    2 layer    fi           4096 Dec  9 09:43 bar/
drwxr-xr-x    2 layer    fi           4096 Nov 11 16:10 foo/

./bar:
total 8
drwxr-xr-x    2 layer    fi           4096 Dec  9 09:43 ./
drwxr-xr-x    4 layer    fi           4096 Jan 22 14:22 ../
lrwxrwxrwx    1 layer    fi             53 Dec  9 09:43 foo -> /net/crikey/home/layer/examples/convert_links/foo/foo

./foo:
total 12
drwxr-xr-x    2 layer    fi           4096 Nov 11 16:10 ./
drwxr-xr-x    4 layer    fi           4096 Jan 22 14:22 ../
-rw-r--r--    1 layer    fi              4 Nov 11 16:10 foo
crikey% 

Now, run convert_links.cl:

crikey% ./convert_links.cl .
bar/foo => ../foo/foo
crikey% ls -l bar
total 0
lrwxrwxrwx    1 layer    fi             10 Jan 22 14:36 foo -> ../foo/foo
crikey% 


bar/foo now points to ../foo/foo instead of
/net/crikey/home/layer/examples/convert_links/foo/foo.  The directory
/home/layer/examples/convert_links can be moved without breaking the
symbolic link in `bar'.
