"""
Command line tool to validate Office document XML files against XSD schemas and tracked changes.

Usage:
    python validate.py <path> [--original <original_file>] [--auto-repair] [--author NAME]

The first argument can be either:
- An unpacked directory containing the Office document XML files
- A packed Office file (.docx/.pptx/.xlsx) which will be unpacked to a temp directory

Auto-repair fixes:
- paraId/durableId values that exceed OOXML limits
- Missing xml:space="preserve" on w:t elements with whitespace
