is compatible with the Bourne Shell, but it also integrates useful features
from the Korn Shell and the C Shell and new improvements of its own.  It
allows command-line editing, unlimited command history, shell functions and
aliases, and job control while still allowing most sh scripts to be run
without modification.")
