[Bioperl-l] get_dbfrom document

[Peng Yu]

According to perldoc Bio::Tools::EUtilities::Info::LinkInfo,
get_dbfrom is alias for get_db().

   get_dbfrom
        Title    : get_dbfrom
        Usage    : my $origdb = $link->get_dbfrom;
        Function : returns referring database
        Returns  : string
        Args     : none
        Note     : alias for get_db()

I'm not sure what get_db() is but I only see get_db. Is get_db the
same as get_db()? If this is true, then get_dbfrom is not an alias for
get_db, because I get different result for the two variables.

Am I understanding it correctly?
