+//go:build generate
+
+// This program generates a property file in Go file from Unicode Character
+// Database auxiliary data files. The command line arguments are as follows:
+//
+// 1. The name of the Unicode data file (just the filename, without extension).
+// Can be "-" (to skip) if the emoji flag is included.
+// 2. The name of the locally generated Go file.
+// 3. The name of the slice mapping code points to properties.
+// 4. The name of the generator, for logging purposes.
+// 5. (Optional) Flags, comma-separated. The following flags are available:
+// - "emojis=<property>": include the specified emoji properties (e.g.
+// "Extended_Pictographic").
+// - "gencat": include general category properties.
+//
