=head1 NAME
bp_extract_feature_seq - extract the corresponding sequence for a specified feature type
=head1 SYNOPSIS
bp_extract_feature_seq [--format FORMAT] [--feature CDS] [--output FILE] [--input] FILE
=head1 DESCRIPTION
This script will extract the sequence for all the features you specify.
=head1 OPTIONS
=over
=item B<-i>, B<--input>
Specifies the sequence file to be read.
=item B<--format>
Format of the file specifed by B<--input>. If not given, it will try to guess the
correct format from the file extension.
=item B<--feature>
Feature to be extracted. By default, it extracts the CDS feature.
=item B<-o>, B<--output>
File where the extracted features will be saved. If not specified, STDOUT is used.
