description="
The MirBSD Korn Shell.

mksh is the MirBSD enhanced version of the Public Domain Korn shell
(pdksh), a Bourne-compatible shell which is largely similar to the
original AT&T Korn shell; mksh is the only pdksh derivate currently
being actively developed.  It includes bug fixes and feature
improvements, in order to produce a modern, robust shell good for
interactive and especially script use.
