Bio::FeatureIO::bed - read/write features from UCSC BED format

SYNOPSIS

  my $in = Bio::FeatureIO(-format => 'bed', -file => 'file.bed');
  for my $feat ($in->next_feature) {
    # do something with $feat (a Bio::SeqFeature::Annotated object)
  }

  my $out = Bio::FeatureIO(-format=>'bed');
  for my $feat ($seq->get_seqFeatures) {
    $out->write_feature($feat);
  }

DESCRIPTION

See <http://www.genome.ucsc.edu/goldenPath/help/customTrack.html#BED>.

Currently for read and write only the first 6 fields (chr, start, end, name, score, strand) are supported.
