+Raw ANSI sequence helpers
+
+## ANSI Writer
+
+```go
+import "github.com/muesli/ansi"
+
+w := ansi.Writer{Forward: os.Stdout}
+w.Write([]byte("\x1b[31mHello, world!\x1b[0m"))
+w.Close()
+```
+
+## Compressor
+
+The ANSI compressor eliminates unnecessary/redundant ANSI sequences.
+
+```go
+import "github.com/muesli/ansi/compressor"
+
+w := compressor.Writer{Forward: os.Stdout}
+w.Write([]byte("\x1b[31mHello, world!\x1b[0m"))
+w.Close()
+```
