NOTES:

1. All matrix files are in the format used in the FASTA2
package and will not work with FASTA3. These files are
still needed for lfasta, lalign, align and align0.

For FASTA3, instead of specifying external files,
the -s option can be used to choose internal matrices.

2. All GenBank divisions are now specified in .fil files,
which are created using the script fil/fil.py
