+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
