=head1 NAME
bp_aacomp - amino acid composition of protein sequences
=head1 SYNOPSIS
bp_aacomp [-f/--format FORMAT] [-h/--help] filename
or
bp_aacomp [-f/--format FORMAT] < filename
or
bp_aacomp [-f/--format FORMAT] -i filename
=head1 DESCRIPTION
This scripts prints out the count of amino acids over all protein
sequences from the input file.
=head1 OPTIONS
The default sequence format is fasta.
The sequence input can be provided using any of the three methods:
=over 3
=item unnamed argument
bp_aacomp filename
=item named argument
bp_aacomp -i filename
=item standard input
bp_aacomp < filename
