libghc-hslogger-doc binary package in Ubuntu Focal arm64

 hslogger is a logging framework for Haskell, roughly similar to
 Python's logging module.
 .
 hslogger lets each log message have a priority and source be associated
 with it. The programmer can then define global handlers that route
 or filter messages based on the priority and source. hslogger also
 has a syslog handler built in.
 .
 This package contains the API documentation.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
