_D_e_s_c_r_i_p_t_i_o_n:

     The functions documented here are intended to make it easier to
     map from a set of manufacturers identifiers (such as you will get
     from the chips etc) to other identifiers.

_U_s_a_g_e:

     getSYMBOL(x, data = "hgu95a")
     getLL(x, data = "hgu95a")
     getGO(x, data = "hgu95a")
     getPMID(x, data = "hgu95a")
     getGOdesc(x, which=c("MF","BP","CC") )

_A_r_g_u_m_e_n_t_s:

       x: The identifiers to be mapped (usually manufacturer)

    data: A character string identifying the data source 

   which: For `getGOdesc' indicates which GO hierarchy to use.

_D_e_t_a_i_l_s:

     Appropriate translations are done. In some cases such as `getLL'
     and `getSYMBOL' there will only be one match and a vector is
     returned. In other cases such as `getPMID' and `getGO' there may
     be multiple matches and a list is returned. For `getGOdesc' the
     input vector is GO identifiers (not manufacturer identifiers) and
     in the output any identifier that does not have a description in
     the selected GO hierarchy (MF, BP or CC) is dropped.

_V_a_l_u_e:

     Either a vector or a list depending on whether multiple values per
     input are possible.

_A_u_t_h_o_r(_s):

     R. Gentleman

_S_e_e _A_l_s_o:

     `multiget'

_E_x_a_m_p_l_e_s:

       data(eset)
       gN <- geneNames(eset)[100:105]
       getSYMBOL(gN)
       gg<- getGO(gN)
       getGOdesc(gg[[2]], "MF")
       getLL(gN)
       getPMID(gN)
