Description:  Summarizes coverage information from basecov files
              created by pileup.sh.  They should be named like
              'sample1_basecov.txt' but other naming styles are fine too.

Usage:        summarizecoverage.sh *basecov.txt out=<output file>

Parameters:
in=<file>           'in=' is not necessary.  Any filename used as a
                    parameter will be assumed to be an input basecov file.
out=<file>          Write the summary here.  Default is stdout.
reflen=-1           If positive, use this as the total reference length.
                    Otherwise, assume basecov files report every ref base.

Please contact Brian Bushnell at bbushnell@lbl.gov if you encounter any problems.
