SPMRL 2013 shared task dependency evaluation script for French.

   EXPECTED FORMAT for marking MWEs:

   The script supposes that all MWEs are flat, with one component governing
   all the other components of the MWE with dependencies labeled <MWE_LABEL>.
   If provided, the additional information of the part-of-speech of the MWE
   is expected to be given as value of a <MWE_POS_FEAT> feature, on the head token of the MWE.

   OUTPUT: 

   The script outputs in any case two evaluations, and possibly a third one :

   - precision/recall/Fmeas on components of MWEs (excluding heads of MWEs)
     A component of MWE is counted as correct if it is attached to the same 
     token as in the gold file, with label <MWE_LABEL>

   - precision/recall/Fmeas on full MWEs
     A MWE is counted as correct if its sequence of tokens also forms 
     a MWE in gold file

   - if both the gold file and the system files do contain at least one <MWE_POS_FEAT> feature,
     then a third evaluation is also provided, which uses a stricter criteria
     for full MWEs : they have to be composed of the same tokens as in gold file AND the gold
     and predicted part-of-speech for the MWE have to match.


   USAGE: perl do_eval_dep_mwe.pl [OPTIONS] -g <gold standard conll> -s <system output conll>

   [ -mwe_label <MWE_LABEL> ] label used for components of MWEs. Default = dep_cpd
   [ -mwe_pos_feat <MWE_POS_FEAT> ] use to define the feature name that marks heads of MWEs. Default = mwehead
