GOA ~~ GHCi On Acid
AUTHOR : Paolo Martini
Maintainer at HackageDB: Chris Done <>
This set of tools is an attempt to bring the wonderful world of lambdabot
commands to the GHC interpreter for ease of use.
The set of commands carefully developed in lambdabot during the years has
become a very useful tool for haskellers. For some it is like an addiction.

:def command lambdabot "lambdabot-command-name"
