SUMMARY = "UNIX Shell similar to the Korn shell"
DESCRIPTION = "Zsh is a shell designed for interactive use, although it is also a \
               powerful scripting language. Many of the useful features of bash, \
               ksh, and tcsh were incorporated into zsh; many original features were added."
