Description:  Summarizes the scafstats output of BBMap for evaluation
of cross-contamination.  The intended use is to map multiple libraries or 
assemblies, of different multiplexed organisms, to a concatenated reference 
containing one fused scaffold per organism.  This will convert all of the 
resulting stats files (one per library) to a single text file, with multiple 
columns, indicating how much of the input hit the primary versus nonprimary 
scaffolds.

Usage:  summarizescafstats.sh in=<file,file...> out=<file>

You can alternatively use a wildcard, like this:
summarizescafstats.sh scafstats_*.txt out=summary.txt

Parameters:
in=<file>       A list of stats files, or a text file containing one stats file name per line.
out=<file>      Destination for summary.

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