"pico" is a simple but powerful text editor. It was originally the pine
 composer, the editor used by the pine email client for writing email messages.
 .
 It has gained popularity since its initial use in that context and is now used
 as a stand-alone editor by many users.
 .
 It is similar to but less powerful than GNU Nano, an editor created with the
 pico interface when the pico license was non-free.
