     ygs98DESCRIPTION maps yeast ORF identifiers to descriptive
     information about genes corresponding to the ORF identifiers

_D_e_t_a_i_l_s:

     This is an R object containing key and value pairs. Keys are ORF
     identifiers and values are the corresponding descriptions of
     genes. Values are vectors of length 1. Probe identifiers that can
     not be mapped to descriptive information are assigned a value NA.
