Read an ancillary DDS.

Documentation

This function searches for an ancillary data file (using the #find_ancillary_file# function) containing the DDS for a dataset. If such a file is found, the function reads it with the #parse# method of the given DDS. A DDS ancillary file ends with #.dds#.
Returns:
TRUE if the dataset DDS was found and read, FALSE otherwise.
Parameters:
dds - The DDS of a dataset. The ancillary DDS, if any, is ``folded'' into the existing DDS information.
dataset - A string containing the name of the dataset whose DDS is to be read.
dir - An optional parameter specifying a secondary directory in which to look for an ancillary DDS file. This is used as an argument to #find_ancillary_file#.
dir - An optional parameter specifying a file name with which to look for an ancillary DDS file. This is used as an argument to #find_ancillary_file#.
