+"""
+将 Wwise Vorbis .wem 文件转换为标准 Ogg Vorbis (.ogg) 文件。
+纯 Python 实现，不依赖 ww2ogg 或 revorb 外部工具。
+
+基于 Wwise RIFF/Vorbis 格式:
+- Codec ID: 0xFFFF
+- Vorbis 数据存储在 "vorb" chunk 中
+- 数据包可直接封装为 Ogg 容器
+
+用法:
+    python wem2ogg.py <input.wem> <output.ogg>
+    python wem2ogg.py --batch <input_dir> <output_dir>
