_D_e_s_c_r_i_p_t_i_o_n:

     mgug4121aENSEMBL is an R object that contains mappings between 
     manufacturer identifiers and Ensembl gene accession numbers.

_D_e_t_a_i_l_s:

     This object is a simple mapping of manufacturer identifiers <URL:
     http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene> to Ensembl
     gene Accession Numbers.

     Mappings were based on data provided by: Entrez Gene (
     ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2
