Description: =====================================================================
         treetools - tree processing
        =====================================================================
        
        treetools is a collection of tools for processing constituency
        treebank trees. It contains algorithms for tree manipulation (such
        as removal of crossing branches), tree analysis, and grammar 
        extraction.
        
        treetools is being developed and maintained at the Department for
        Computational Linguistics at the Institute for Language and
        Information at the University of Düsseldorf, Germany (see
        http://phil.hhu.de/beyond-cfg). The project is sponsored by Deutsche
        Forschungsgemeinschaft (DFG).

        Installation
        ============
        
        Requirements:
        
        - Python 2.7.3+
        
        To install the latest release from the Python package index, type::
        
            pip install treetools --user
        
        To install the latest version clone the git repository and run::
        
            python setup.py install --user
        
        within the repository directory. 
        
        If you have superuser privileges and want to perform a system-wide installation, omit the `--user` option, respectively.
        
        Running
        =======
        
        Syntax
        ------
        
        To run treetools, type::
        
            treetools [subcommand] [parameters] [options]
        
        Available subcommands are:
        
        - ``transform``: Process treebank trees. Run transformations and convert between different formats.
        - ``grammar``: Extract grammars for different parsers from treebanks.
        - ``treeanalysis``: Analyze certain properties of treebank trees, such as, e.g., gap degree.
        
        To get see the available parameters for a subcommand, type::
        
            treetools [subcommand] --help
        
        To get verbose help on available transformation algorithms, available options, etc., type::
        
            treetools [subcommand] --usage
        
        Examples
        --------
        
        To attach the punctuation in TIGER and remove its crossing branches while converting it from TigerXML to a bracket format, type::
        
            treetools transform tiger.xml tiger.preproc.xml --trans root_attach boyd_split negra_mark_heads boyd_split raising --src-format tigerxml --dest-format export
        
        To extract the bare sentences (one per line) from a treebank in bracketed format, such as the Penn Treebank, type::
        
            treetools transform treebank.brackets treebank.terminals --src-format brackets --dest-format terminals
        
        To delete the traces and co-indexation from the Penn Treebank, type::
        
            treetools transform ptb ptb.notrace --transform ptb_transform --src-format brackets --dest-format brackets
        
        To extract an left-to-right binarized LCFRS with v1/h2 markovization in rparse format from an export-format treebank, type::
        
            treetools grammar input_treebank output_grammar leftright --dest-format rcg --markov v:1 h:2
