+duplicates in read-id grouped paired-end SAM files.  It can also optionally
+output discordant read pairs and/or split read mappings to separate SAM files,
+and/or unmapped/clipped reads to a separate FASTQ file. When marking
+duplicates, samblaster will require approximately 20MB of memory per 1M read
+pairs.")
