This splits the current “clean” rule into proper clean (cleaning of
build artifacts) and maintainer-clean (cleaning of distributed files).
This should make it better for Debian packaging.

This makes hail compile and get a request parsed via IAlloc, but nothing
more.

It was missing a dependency on the Version.hs file, so right after “make
clean”, a “make dist” used to fail.

Use the $HPROGS variable instead of hardcoding the program names.

This removes most of the content of the README file (obsoleted by new
algorithm and man pages), modifies the Makefile to include the built
documentation in the source archive (so that haddock/hscolour are not
needed) and updates the haddock-prologue with current information.

This patch does some small changes:
  - fixes a comment
  - export more node functions (unneeded now, but hscan will use them)
  - fixes Makefile rule for building the programs

The modules are moved from the ‘top’ namespace to ‘Ganeti.HTools’, in
compliance with standard practices.

This patch attempts to embed the VCS id in binaries, based on the way
other projects seem to do this.

This fixes the doc issue which exists since the addition of hbal. Now
make doc makes sense again.

This is the initial import of release 0.0.3.
