 define Package/mksh/description
-MirBSD version of ksh
+mksh is the MirBSD enhanced version of the Public Domain Korn
+shell (pdksh), a Bourne-compatible shell which is largely si-
+milar 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.
+mksh has UTF-8 support (e.g. in the emacs editing mode); R38c
+corresponds to OpenBSD 4.5-current ksh (without GNU bash-like
+$PS1 and fancy character classes).  The code has throughoutly
+been cleaned up and simplified, bugs fixed, standards compli-
+ance added, and several enhancements (for extended compatibi-
+lity to other modern shells - as well as a couple of its own)
+have been placed.
