libghc-hslogger-dev 1.2.10+dfsg-4build1 (ppc64el binary) in ubuntu cosmic

 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 a library for the Haskell programming language.
