Very restricting library
While readline offers very good (though occasionally flawed) line editing - its macro support is lacking. Readline's many quirks, poor documentation, and inflexibility, isn't a bonus either. When using this library you should consider that you might end up spending more time working around readline's limitations than if you would have taken a couple of days to add your own input editing support. Not to mention that the library isn't installed on many system.
