=item getAbsPath($path)

This procedure attempts to convert a path provided by the user on the
command line into an absolute path. It should be able to handle "~"
paths and conventional relative paths using ".." or ".". Resolution of
links should follow the convention of "Cwd::realpath".

B<Parameters:>

    $dirRef         - path (converted to absolute path in place)

B<Returns:>

    returns zero if successful, non-zero otherwise.
