-## Overview
-
-`fgsv` contains tools for gathering evidence for structural variants
-from aligned reads. The `SvPileup` tool searches for split read mappings
-and read pairs that map across breakpoints, emitting verbose information
-similar to other "piluep" tools for small variant detection, but in this 
-case for structural variation detection.  The `AggregateSvPileup` attempts
-to aggregate information across "nearby" pileups, which is useful as often
-the genomic start and end of a breakpoint is not always precise.  The tools
-aim to be as sensitive as possible to find these evidence, but do neither
-perform structural variation calling nor genotyping.
