"""
Opens a folder, and recursively feeds all OGG files in it to
optivorbis.exe
for recompression and reducing file size.

optivorbis.exe is available from https://github.com/OptiVorbis/OptiVorbis/

WARNING:
Source files are replaced! No backup, no mercy!

Also supports commandline arguments. Run:

``pythonw.exe "dir OPTIVORBIS ogg.py" "target_name"``

to open in "target_name" dir, or add

``pythonw.exe "dir OPTIVORBIS ogg.py" "%1"``

to "Send to" or right-click or .bat (use exact addresses of pythonw and this file)
