Fig is a Haskell package for parsing and manipulation of [Xfig files][1].

The package has a Cabal setup and can be installed this way:

    $ runhaskell Setup configure
    $ runhaskell Setup build
    $ sudo runhaskell Setup install

You can use the package without doing an install by editing the
`Main.hs` file to suit your needs and building the program with the
following command:

    $ ghc --make Main.hs -o fig2fig

Run the program with a FIG file as input and view the results:

    $ ./fig2fig < transitive.fig > out.fig
    $ xfig out.fig

The package has a [home page][0] with more information on its use and
a [HackageDB page][2] with all releases of the package.
