Just a nit.  Bash is `based on the Bourne shell' in that it implements the
Posix 1003.2 spec, which is based on the System V shell, but it is a
completely new implementation; there is no sh source in it.  Ksh and tcsh
can be said to be `based on' the Bourne and C shells, respectively, because
they each contain portions of those shells.
