This is the Haskell Fig library for parsing and manipulating Xfig
files.

The library is provided as a Cabal package; it can be installed as
follows:

    runhaskell Setup.hs configure
    runhaskell Setup.hs build
    sudo runhaskell Setup.hs install

Packages such as parsec that the library depends on can be found in
the package repository (http://hackage.haskell.org).

To try out the library, edit the Main.hs file to suit your needs and
build the program with the following command:

    ghc --make Main.hs -o fig2fig

Feed a FIG file to the program and view the results:

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