## Usage

```

Usage: csv2arrow [OPTIONS]  [ARROW]

Arguments:

      Input CSV file

  [ARROW]  Output file, stdout if not present

Options:

  -s, --schema-file 

          File with Arrow schema in JSON format

  -m, --max-read-records 

          The number of records to infer the schema from. All rows if not present. Setting max-read-records to zero will stop schema inference and all columns will be string typed

      --header 

          Set whether the CSV file has headers [possible values: true, false]

  -d, --delimiter 

          Set the CSV file's column delimiter as a byte character [default: ,]

  -p, --print-schema

          Print the schema to stderr

  -n, --dry

          Only print the schema

  -h, --help

          Print help information

  -V, --version

          Print version information

```

The --schema-file option uses the same file format as --dry and --print-schema.
