+# sfx2h.py
+
+This tool requires Python 3 and can generate a C include file from a sfx file
+as saved by `sfxed`.
+
+Being Python is easier to modify and adapt to your own needs!
+
+Example:
+```
+sfx2h.py ../test.sfx sounds
+```
+
+Will generate:
+```
+
+/* file: ../example/test.sfx */
+#ifndef SOUNDS_H_
+#define SOUNDS_H_
+
+#include "beeper.h"
+
+enum sounds_enum {
+	SOUNDS_LASER = 1,
+	SOUNDS_ZAP,
+	SOUNDS_DRILL,
+	SOUNDS_EXPLO,
+};
+
+#ifdef LOCAL
+
+const struct beeper_sfx sounds[] = {
+{ 0x01, 0x20, 0x78, 0xfc, 0x00 },
+{ 0x02, 0x10, 0x0c, 0x00, 0x00 },
+{ 0x01, 0x20, 0x01, 0x00, 0x00 },
+{ 0x02, 0x20, 0x80, 0xff, 0x00 },
+};
+
+#else
+extern const struct beeper_sfx sounds[];
+#endif
+#endif // SOUNDS_H_
+```
+
+You can include it normally on any C file, just remember to define `LOCAL`
+before included in the module containing the data (only once!).
+
+## CAVEATS
+
+* Is not perfuming exhaustive checks on the effects' names or the provided id
+* `LOCAL` is not undefined after used
