=head1 NAME

bp_genbank2gff.pl - Load a Bio::DB::GFF database from GENBANK files.

=head1 SYNOPSIS

  % bp_genbank2gff.pl -d genbank -f localfile.gb
  % bp_genbank2gff.pl -d genbank --accession AP003256
  % bp_genbank2gff.pl --accession AP003256 --stdout

=head1 DESCRIPTION

This script loads a Bio::DB::GFF database with the features contained
in a either a local genbank file or an accession that is fetched from
genbank.  Various command-line options allow you to control which
database to load and whether to allow an existing database to be
overwritten.

The database must already have been created and the current user must
have appropriate INSERT and UPDATE privileges.  The --create option
will initialize a new database with the appropriate schema, deleting
any tables that were already there.

=head1 COMMAND-LINE OPTIONS

Command-line options can be abbreviated to single-letter options.
e.g. -d instead of --database.

   --create                 Force creation and initialization of database
   --dsn       <dsn>        Data source (default dbi:mysql:test)
   --user      <user>       Username for mysql authentication
   --pass      <password>   Password for mysql authentication
   --proxy     <proxy>      Proxy server to use for remote access
   --stdout                 direct output to STDOUT
   --adaptor   <adaptor>    adaptor to use (eg dbi::mysql, dbi::pg, dbi::oracle)   --viral                  the genome you are loading is viral (changes tag
                                 choices)
   --source    <source>     source field for features ['genbank']
    EITHER --file           Arguments that follow are Genbank/EMBL file names
    OR --gb_folder          What follows is a folder full of gb files to process    OR --accession          Arguments that follow are genbank accession numbers
                                 (not gi!)
    OR --acc_file           Accession numbers (not gi!) in a file (one per line,                                 no punc.)
    OR --acc_pipe           Accession numbers (not gi!) from a STDIN pipe (one
                                 per line)
