+"""Extract All-in-One WP Migration .wpress archive.
+
+Usage:
+    python3 extract_wpress.py <path/to/file.wpress> <output/directory>
+
+The .wpress format is a sequential binary archive with 4377-byte headers:
+    255 bytes  filename (null-padded)
+     14 bytes  file size in bytes (ASCII digits, null-padded)
+     12 bytes  mtime unix timestamp (ASCII digits, null-padded)
+   4096 bytes  relative path (null-padded)
+Followed immediately by the raw file bytes, then the next header.
