      <p>The program scans a dna sequence file, looking for tandemly repeated
patterns where the period of the repeat has a user specified *size* from
1 to 32 nucleotides.  A possible repeat is found if *lookcount*
characters are repeated at a separation of *size*.</p> 
<p>Example: Suppose size is 7 and lookcount is 3. Then the sequence
                <pre>
                ACGTGTCCGTA 
                 ^^^   ^^^
                </pre>
could be part of a possible repeat of the pattern CGTGTC
because the first 3 characters CGT are repeated at a separation of 7.</p>

<p>Once a possible pattern is found, the program uses dynamic programming
to compute a similarity score of the pattern versus the sequence in
the area where the pattern was found.  The dynamic programming uses
weights for single indels rather than gap functions.  This is so that
the program quickly identifies the repeats rather than producing an
optimal alignment score.</p>

<p>If the similarity score exceeds a threshold, then a consensus pattern is
computed.  This consensus is aligned with the sequence and the
alignment is displayed.</p>
