The panicwrap package provides functions for capturing and handling panics in your application. It does this by re-executing the running application and monitoring stderr for any panics. At the same time, stdout/stderr/etc. are set to the same values so that data is shuttled through properly, making the existence of panicwrap mostly transparent. Panics are only detected when the subprocess exits with a non-zero exit status, since this is the only time panics are real. Otherwise, "panic-like" output is ignored.
