     drosgenome1FLYBASE is an R object that contains mappings between 
     manufacturer identifiers and FlyBase 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 Flybase
     Accession Numbers.

     Mappings were based on data provided by: Entrez Gene (
     ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2009-Mar11
