+# Flac2Opus
+
+script to batch convert .flac files to .opus files
+
+## Usage
+
+`./convert.fish sourcedir destdir`
+
+## Requirements
+
+You need golang & opus-tools (for opusenc). you can likely substitute it with ffmpeg if you would like to modify the script, though.
+
+golf (*GO* *L*ist *F*iles) and gold (*GO* *L*ist *D*irectories) are expected to be in your $PATH.
