Read & Write BAM/SAM Library Software

The software reads the beginning of files opened for reading to determine if it is SAM/BAM. To determine the format (SAM/BAM) of files open for writing, the software checks the output file's extension. If the extension is "bam" it writes a BAM file, otherwise it writes a SAM file.

The library is found in statgen/lib/bam.
