    Frontend plugins.
    
    Summary:
    Frontend plugins enable users to write plugins to replace
    GHC major modes.  E.g. instead of saying
    
        ghc --make A B C
    
    a user can now say
    
        ghc --frontend GHC.Frontend.Shake A B C
    
    which might provide an alternative implementation of a multi-module
    build.  For more details, see the manual entry.
