+This is a simple package to get around the problem of reusing addresses.
+The go `net` package (to my knowledge) does not allow setting socket options.
+This is particularly problematic when attempting to do TCP NAT holepunching,
+which requires a process to both Listen and Dial on the same TCP port.
+This package makes this possible for me. It is a pretty narrow use case, but
+perhaps this package can grow to be more general over time.
