Hi,
It depends on exactly how you want to control it, but at least some
control is fairly easy.

Hi
If you simply want to start a batch Haskell program, and see its
output as HTML in a browser, you can use the cgi [1] or fastcgi [2]
libraries listed on Hackage.
This is the approach that Hoogle takes, and turned out to be very
easy. The code is all available, so you can start from that.

As far as I remember you started the bootstrapping with the ghc built

Not sure if this is the case but if you don't delete the old object

Ah. Yeah, that could well make a big difference... (Especially on a
machine with insufficient RAM.)

Well, I answered my own question. Unlike UNIX, specifying a library
without the leading lib causes the library to not be found. Not sure
if that's a GHC linking problem or what. Changing the library
