Usage: $0 [options] -- [WHICH FEATURES]
output GFF3 for selected database features
Options:
-d --dsn The database name ($DSN)
-a --adaptor The storage adaptor to use ($ADAPTOR)
-u --user User to connect to database as
-p --password Password to use to connect to database
-g --gff3opt flag options to gff3_string (i.e.: pass -gffopt 1 to recurse)
WHICH FEATURES: any remaining options after '--' will select
a subset of features. The arguments are identical to those
accepted by Bio::DB::SeqFeature::Store->features().
