Multifocal
This cabal package can be installed with:
$ cabal install multifocal
For a manual install, execute:

For an example, try running the following steps:
1) generate a target XML Schema file and an optimized lens executable from the source XML Schema file imdb.xsd according to the transformation imdb.2lt.
$ multifocal -i examples/imdb.xsd -t examples/imdb.2lt -o examples/imdb2.xsd -c examples/Imdb.hs -e
2) compile the resulting file
$ ghc --make examples/Imdb.hs -o imdb
3) Migrate a source XML document into a target XML document
$ ./imdb -s examples/imdb.xml -f -o examples/imdb2.xml
4) Translate an updated target XML document back to the source
./imdb -s examples/imdb.xml -t examples/imdb2mod.xml -b -o examples/imdbmod.xml
