    absolute-symlink.sh: check for absolute symlinks on a FreeBSD system
    
    The purpose of this script is to detect absolute symlinks on
    a machine, e.g.:
    
        /etc/localtime -> /usr/share/zoneinfo/UTC
    
    Some of these absolute symbolic links can be created intentionally,
    but it is usually better to use relative symlinks.
    
    You can run the script after `make installworld', or any other
    make targets thats installs files.
    
    You can also check your local ports with:
    
       env ABSOLUTE_SYMLINK_DIRS=/usr/local ./absolute-symlink.sh
