 an extended version of the [nosh minimal POSIX C shell](https://github.com/jstmaxlol/nosh), still for \*NIX dudes!
 
+### differences
+-   uses [GNU Readline] which is an external dependancy \
+    but it allows for great arrow-keys handling, history and \
+    MORE without having to touch `<termios.h>`.
+
+-   it also fixes some minor memory leaks and stuff from nosh.
