+xlsx_pack.py — Pack a working directory back into a valid xlsx file.
+
+Usage:

+
+Requirements:
+    - source_dir must contain [Content_Types].xml at its root
+    - All XML files are re-validated for well-formedness before packing
+
+The resulting xlsx is a valid ZIP archive with correct OOXML structure.
