_D_e_s_c_r_i_p_t_i_o_n:

     A set of gene names may have been used to report yeast genes
     represented by ORF identifiers. One of these names is chosen to be
     the primary gene name, and the others are considered aliases. This
     R object provides mappings between the primary name and aliases.

_D_e_t_a_i_l_s:

     Each primary name maps to a vector of alias names. If there are no
     aliases, the vector will contain 'NA'.
