+ * This is a simple, counts-and-cutoffs based tool for calling indels from aligned (preferrably MSA cleaned) sequencing
+ * data. Two output formats supported are: BED format (minimal output, required), and extended output that includes read
+ * and mismtach statistics around the calls (tuned on with --verbose). The calls can be performed from a single/pooled sample,
+ * or from a matched pair of samples (with --somatic option). In the latter case, two input bam files must be specified,
+ * the order is important: indels are called from the second sample ("Tumor") and additionally annotated as germline
+ * if even a weak evidence for the same indel, not necessarily a confident call, exists in the first sample ("Normal"), or as somatic
+ * if first bam has coverage at the site but no indication for an indel. In the --somatic mode, BED output contains
+ * only somatic calls, while --verbose output contains all calls annotated with GERMLINE/SOMATIC keywords.
