OTP-like supervision trees in Haskell.

capataz enhances the reliability of your concurrent applications by offering supervision of green threads that run in your application.

Advantages over standard library:

• Links related long-living processes together under a common capataz supervisor, with restart/shutdown order

• Set restart strategies (Permanent, Transient, Temporary) on IO sub-routines on a granular level

• Set restart strategies on a pool of long-living worker threads (AllForOne, OneForOne)

• Complete telemetry on the sub-routine lifecycle of your application (start, error, restarts, shutdown)
