+# char-spinner
+
+Put a little spinner on process.stderr, as unobtrusively as possible.
+
+## USAGE
+
+```javascript
+var spinner = require("char-spinner")
+
+// All options are optional
+// even the options argument itself is optional
+spinner(options)
+```
+
+## OPTIONS
+
+Usually the defaults are what you want. Mostly they're just
+configurable for testing purposes.
+
+* `stream` Output stream. Default=`process.stderr`
+* `tty` Only show spinner if output stream has a truish `.isTTY`. Default=`true`
+* `string` String of chars to spin. Default=`'/-\\|'`
+* `interval` Number of ms between frames, bigger = slower. Default=`50`
+* `cleanup` Print `'\r \r'` to stream on process exit. Default=`true`
+* `unref` Unreference the spinner interval so that the process can
+ exit normally. Default=`true`
+* `delay` Number of frames to "skip over" before printing the spinner.
+ Useful if you want to avoid showing the spinner for very fast
+ actions. Default=`2`
+
+Returns the generated interval, if one was created.
