# Merges foundry data to create indexer friendly documents
# ndiewald, 2014/10/29

sub printhelp {
  print <<'EOHELP';

Merge foundry data based on a tokenization and create indexer friendly documents.

Call:
prepare_index.pl -z --input <directory> --output <filename>

--input|-i <directory>          Directory of the document to index
--output|-o <filename>          Document name for output (optional),
                                Writes to <STDOUT> by default
--overwrite|-w                  Overwrite files that already exist
--token|-t <foundry>[#<layer>]  Define the default tokenization by specifying
                                the name of the foundry and optionally the name
                                of the layer. Defaults to OpenNLP#tokens.
--skip|-s <foundry>[#<layer>]   Skip specific foundries by specifying the name
                                or specific layers by defining the name
                                with a # in front of the foundry,
                                e.g. Mate#Morpho. Alternatively you can skip #ALL.
                                Can be set multiple times.
--allow|-a <foundry>#<layer>    Allow specific foundries and layers by defining them
                                combining the foundry name with a # and the layer name.
--primary|-p                    Output primary data or not. Defaults to true.
                                Can be flagged using --no-primary as well.
--human|-m                      Represent the data human friendly,
                                while the output defaults to JSON
--pretty|-y                     Pretty print json output
--gzip|-z                       Compress the output
                                (expects a defined output file)
--log|-l                        The Log4perl log level, defaults to ERROR.
--help|-h                       Print this document (optional)
