Command-line Usage:
  After installation, you can use OpenOCR in three ways:

  1. Using the 'openocr' command (recommended):
     openocr --task ocr --input_path image.jpg

  2. Using 'python -m openocr':
     python -m openocr --task ocr --input_path image.jpg

  3. Running the script directly:
     python openocr.py --task ocr --input_path image.jpg

Examples:
  # Detection task
  openocr --task det --input_path image.jpg

  # Recognition task
  openocr --task rec --input_path image.jpg --mode server

  # OCR task (detection + recognition)
  openocr --task ocr --input_path image.jpg --is_vis

  # OCR with custom output path
  openocr --task ocr --input_path ./images --output_path ./results

  # UniRec task (universal recognition)
  openocr --task unirec --input_path image.jpg --max_length 2048

  # Doc task (document OCR with layout)
  openocr --task doc --input_path document.jpg --use_layout_detection --save_vis --save_json --save_markdown

  # Doc task with PDF input
  openocr --task doc --input_path document.pdf --use_layout_detection --save_vis --save_json --save_markdown

  # Doc task with custom models
  openocr --task doc --input_path doc.jpg --layout_model path/to/layout.onnx \\
         --encoder_model path/to/encoder.onnx --decoder_model path/to/decoder.onnx --use_layout_detection --save_vis --save_json --save_markdown
