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

     For any chip, this function computes the map from  unique Entrez
     Gene ID to all probes.

_U_s_a_g_e:

     p2LL(data)

_A_r_g_u_m_e_n_t_s:

    data: The character string naming the chip.

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

     This function is deprecated.

     This is essentially the computation of the reverse map, we store
     probe to Entrez gene information in the 'ENTREZID' environment.
     This is used to compute the inverse mapping.

_V_a_l_u_e:

     A list, with length equal to the number of unique Entrez Gene IDs
     on the chip, the elements correspond to the probes that map to the
     Gene ID.

_A_u_t_h_o_r(_s):

     R. Gentleman

_S_e_e _A_l_s_o:

     'getEG'
