Two of the bugs were passing the wrong accessor function to the pretty
printer.

The third bug was that the pretty printer rendered "foo\\bar" as
"foo\bar", but actually in order to get the slash into the string, the
user would have to have used the quote syntax.  I think we decided
that the quote syntax meant a haskell string, so they should input it
as "foo\\bar", of course internally represented as "foo\bar', but when
printed, it should show two slashes again.

** add a newline to the end of the installed package description
** When pretty-printing free-format text fields, align the lines vertically
  (so that following lines will be seen as continuations) and replace empty
  lines with "." (so they'll be correctly re-parsed, instead of looking
  like a stanza separator).

** revert to getting main module from the right place
** make singleStanza ignore comment lines too

** haddock fixes

** Add the following fields to PackageDescription:
  
  	buildPackage   :: Bool,         -- ^ package is buildable here
  	ccOptions      :: [String],     -- ^ options for C compiler
  	ldOptions      :: [String],     -- ^ options for linker
  	frameworks     :: [String],
  
  When these are system dependent (as they often are), they will need to be
  overridden, but the mechanism is left to the Cabal user.
  
  Not that I've treated these as basic fields, so they apply to the library
  (if any) and all executables in the package.  The overriding is easier
  that way.

** Make the build prefix settable with the --builddir option to configure
  (in Simple), save this in the LocalBuildInfo, and use it in subsequent
  phases.
  
  This is useful for the Hugs build, where we want to place the built
  libraries so that we can easily use them inplace.

** Some rearrangement, centring on changes to the definition of
  PPSuffixHandler:
  
  * removed the special treatment of literate source: a separate
    preprocessor can be used for these if required.
  
  * handlers can use package and local build info to construct the
    appropriate preprocessor.
  
  Also, the supplied suffix handlers list now only has entries for suffixes
  that need preprocessing (i.e. not .hs or .lhs).  Dummy entries for the
  suffixes handled by the compiler are added internally.

**  Add a function getOptionsFromSource to fetch LANGUAGE and OPTIONS pragmas
  from the initial part of a Haskell source module (as proposed by SimonM
  on the libraries list).
  
  Also export the auxiliary function stripComments, which does what it says,
  optionally preserving pragmas.

- Rename Compat.* modules to Distribution.Compat.*
- Add {-# OPTIONS -cpp #-} to a few modules
- Distribution.Compat.ReadP: use real ReadP in GHC 6.3+
- new module: Distribution.Extension, contains Extension type
  formerly from Distribution.Misc.
- new module: Distribution.License, contains License type
  formerly from Distribution.Misc.
- remove Distribution.Misc
- new module: Distribution.ParseUtils, containing various parsing utilities
  formerly from Distribution.Package, that are re-used in 
  Distribution.InstalledPackageInfo.
- new module: Distribution.PackageDescription contains everything related
  to PackageDescription, which was formerly in Distribution.Package.
- Distribution.Package now contains only PackageId-related stuff.
- Distribution.InstalledPackageInfo: update for use in GHC, add
  parsing/pretty-printing.
- Compat.H98 is now Distribution.Compat.Error (it contained only stuff
  related to the Error monad, which isn't H98 anyway).
- remove imports of H98 libs (use hierarchical ones instead)
- configure now detects the GHC version (but doesn't do anything with it... yet)
