Hi all,
I've attached the (long-awaited) patch adding a 'cabal init' command.
There's still lots that could be improved but I think it's now at a
useful/complete enough state to be released into the wild. Credit also
goes to Benedikt Huber who developed a lot of the automagic-guessing
heuristic goodness.
Naturally, comments/suggestions/improvements welcome!

[Fix calculation of paths in check for bindir symlink overwriting

us get away with it. The Solaris realpath() is stricter.
The new implementation is also simpler, relying on the fact that
the canonicalizePath function will resolve symlinks.

[Make the documentation toggle determine if we make the haddock index
Duncan Coutts <duncan at haskell.org>**20090707013030
Previously the --haddock-index=template flag controled both the
template used and whether it's used at all. When no path was set
then it was not used. The problem with that is that since we are
not enabling this feature by default then the default is blank.
That is the default config file would look like:
-- haddock-index:
which doesn't help anyone discover what it means or what a
sensible setting would be. By having a separate toggle to
enable/disable we can have a default for the index file which
makes it easy to discover in the config file:
-- documentation: False
-- doc-index-file: $datadir/doc/index.html
All the user has to do is uncomment the first line and use True.

version 3 preference for things like:

also ignore preferences for base given on the command line.

[Parse compiler field from old config files correctly
Duncan Coutts <duncan at haskell.org>**20090116002851
Really old versions of cabal-install generated a default config

config file parser from the command line parser means we end up
with a case-sensitive parser as it only matches the exact
command line flags. So we hack it and add in a traditional
parser for that field only. Really the command line and config
file infrastructure needs rewriting again. Sigh.

[Use a more precise package substitution test in improvePlan
Duncan Coutts <duncan at haskell.org>**20081219215922
This is where we take a valid plan and we "improve" it by swapping
installed packages for available packages wherever possible. This
change is to the condition we use in deciding if it is safe to use
the installed package in place of a reinstall. Previously we checked
that the dependencies of the installed version were exactly the same
as the dependencies we were planning to reinstall with. That was
valid but rather conservative. It caused problems in some situations
where the installed package did not exactly match the available
package (eg when using development versions of a package or of ghc).
What we do now is test if the extra constraints implied by selecting
the installed version are consistent with the existing set of
constraints. This involves threading the constraint set around. In
theory this should even cope with adding additional packages to the
plan as a result of selecting an installed package.
]
[Use installed constraints instead of hiding versions of the base package
Duncan Coutts <duncan at haskell.org>**20081219193740
We want to stop cabal-install from accidentally trying to upgrade
the base package since this doesn't work in most cases. We used to
achieve that by deleting the base package from the available package
index. We now do it by leaving the package index as is and instead
adding a constraint that we pick only an installed version of base.
This is a nicer hack and has the potential to give better error
messages.

[Extend the invariant on the Constraints ADT

between pots in various slightly tricky ways.
]
[Fix constraint set handling for installed constraints
Duncan Coutts <duncan at haskell.org>**20081219182328
A rather subtle bug. The code was actually correct but the transitionsTo
assertion was not accounting for a transition between the case where
a package's available version had been excluded and then the whole thing
got excluded by a version constraint. It counted one side as a loss
without a corresponding gain on the other side.

Previously when we selected base 4 (and as a consequence

However we need to be slightly careful or we end up deciding
to do silly things like rebuild haskell98 against base 3.
That would happen because the h98 package doesn't constrain
the choice to one or the other and we would prefer base 3.
So we have to add that we really prefer whatever it uses
currently (if any).

assume there was only one version left when finalising. For
paired packages there may be two versions left if the package
did not directly constrain the choice to just one. If there is
more than one version remaining then we have to pick between
them. At the moment we still pick the highest version, but
later we can take a global preference or polciy into account.
