=head1 NAME

bp_remote_blast.pl - script for submitting jobs to a remote blast server
(ncbi blast queue at this time)

=head1 SYNOPSIS

% bp_remote_blast.pl -p blastp -d ecoli -e 1e-5 -i myseqs.fa

=head1 DESCRIPTION

This module will run a remote blast on a set of sequences by
submitting them to the NCBI blast queue and printing the output of the
request.
