  42 =head1 NAME
  43
  44 bp_local_taxonomydb_query - query a local TaxonomyDB for species or taxonid
  45
  46 =head1 DESCRIPTION
  47
  48 This script provides an example implementation of access to a local
  49 Taxonomy database implemented with Berkeley DB (DB_File module is needed).
  50
  51 Usage:
  52
  53  bp_local_taxonomydb_query.PLS: [-v] --nodes nodes.dmp --names names.dmp "Genus1 species1" "Genus2 species2"
  54
  55 Providing the nodes.dmp and names.dmp files from the NCBI Taxonomy
  56 dump (see Bio::DB::Taxonomy::flatfile for more info) is only necessary
  57 on the first time running.  This will create the local indexes and may
  58 take quite a long time.  However once created, these indexes will
  59 allow fast access for species to taxon id OR taxon id to species name
  60 lookups.
