Krasimir:
  added hs-source-dirs (ross added docs)

  Add other-files field to PackageDescription. This is a list files
  which belong to the package but aren't compiled. These files are
  copied and packaged from sdist command.

Ross:
  fixes to buildHugs and sdist after hs-source-dirs changes.
  
  Also simplified smartCopySources a bit.

  document sdist and new other-files field.

* Exporting Distribution.Compat.FilePath and Distribution.GetOpt.
  I'm using GetOpt from Cabal 'cause I fixed a bug in it which I haven't commited to CVS yet.
In Distribution.Simple.Config:
* Made 'getInstalledPackagesAux' and 'configCompilerAux' which aren't using ConfigFlags
  since cabal-get defines it own ConfigFlags.
* Changed 'configCompilerVersion' to take a verbose argument instead of a ConfigFlags.
* Exported those functions.

Now exporting getInstalledPackages from Distribution.Simple.Configure since it's needed by cabal-get.

  getInstalledPackages: ignore lines beginning with "Creating", so that
  we can understand this ghc-pkg output from 6.4:

  /home/simonmar/.ghc/i386-linux-6.4/package.conf:

  add with-c2hs option to configure, pass cpp options to c2hs, plus a
  little refactoring.
  
  This involves interface changes: changed type of ppC2hs, extra fields
  in ConfigFlags and LocalBuildInfo.

This is necessary in Mac OS X and on Solaris.

It is possible that this might cause problems for systems that use
setup copy to build and then use cp to install files, since the
library modification time will change.  I think this is only the case
on Mac OS X and Solaris.

[from Distribution.Simple.Configure]
 * Exporting getInstalledPackagesAux and configCompilerAux.
 * Refactored ConfigFlags out of configCompilerAux, findCompiler,
   configCompilerVersion and guessPkgToolFromHcPath.
 * Changed the verbosity of getInstalledPackages, findCompiler,
   configCompilerVersion and guessPkgToolFromHcPath.

Including a test case from J?r?my Bobbio.

Previously, we weren't linking in _stub.o files to the library, though
they are produced by the build.  Now we link them in.  I assume that
ghc --make does the right thing for executables, haven't tested this.

Also implemented ./setup clean for getting rid of Foo_stub.{h,c} files
for both executables and libraries.  These files aren't put into the
dist/build directory (can they be?) so I had to add a bit of extra
logic here.

The bug caused unknown long opts to get stripped of their argument (--test=arg => --test).

  Fix handling of end-of-options markers (--).
  getOpt would correctly return the non-options after the marker, but it
  would return errors for things after the marker that looked like options.
