Friends for --print-libdir

[George Russell]

I think there should be a GHC option --print-sharedir
(or you could call it --print-datadir), corresponding
to ghc --print-libdir.  Thus on our system
    ghc --print-libdir
prints out
    /home/linux-bkb/ghc/ghc-6.2.1/lib/ghc-6.2.1
and I would like
    ghc --print-sharedir
to print out
    /home/linux-bkb/ghc/ghc-6.2.1/share/ghc-6.2.1

At the moment I use
    ghc  --print-libdir | sed -e 's+/lib/\([^/]*\)$+/share/\1+g
but this isn't exactly the happiest of solutions.

The reason my scripts want access to the share directory is that
they want access to HTML files and Haddock interfaces stored there.
