Installation instructions for the Cabal library

If you also want the `cabal` command line program then you need
the `cabal-install` package in addition to this library.

Installing as a user (no root or administer access)

    ghc --make Setup
    ./Setup configure --user
    ./Setup build
    ./Setup install

Note the use of the `--user` flag at the configure step.

This will install into `$HOME/.cabal/` on unix and into
`$Documents and Settings\$User\Application Data\cabal\` on Windows
If you want to install elsewhere use the `--prefix=` flag at the
configure step.

Installing as root / Administrator

    ghc --make Setup
    ./Setup configure
    ./Setup build
    sudo ./Setup install

This will install into `/usr/local` on unix and on Windows it will
install into `$ProgramFiles/Haskell`. If you want to install
elsewhere use the `--prefix=` flag at the configure step.

Working with older versions of GHC and Cabal

It is recommended just to leave any pre-existing version of Cabal
installed. In particular it is *essential* to keep the version that
came with GHC itself since other installed packages need it (eg the
"ghc" api package).

Prior to GHC 6.4.2 however, GHC didn't deal particularly well with
having multiple versions of packages installed at once. So if you
are using GHC 6.4.1 or older and you have an older version of Cabal
installed, you probably just want to remove it:

    ghc-pkg unregister Cabal

or if you had Cabal installed just for your user account then:

    ghc-pkg unregister Cabal --user

Your Help

To help us in the next round of development work it would be
enormously helpful to know from our users what their most pressing
problems are with Cabal and Hackage. You probably have a favourite
Cabal bug or limitation. Take a look at our [bug tracker]. Make sure
the problem is reported there and properly described. Comment on the
ticket to tell us how much of a problem the bug is for you. Add
yourself to the ticket's cc list so we can discuss requirements and
keep you informed on progress. For feature requests it is very
helpful if there is a description of how you would expect to
interact with the new feature.

[bug tracker]:


You can get the code from the web page; the version control system we
use is very open and welcoming to new developers.

You can get the main development branch:

> darcs get --partial

and you can get the stable 1.4 branch:

> darcs get --partial
