	Quick installation notes for PD KornShell

PD KornShell can be installed on 4.2+ BSD systems, System V, and
POSIX-compatable systems.  The makefiles all define _BSD, change
this to _SYSV, or _POSIX.  The makefiles also contain CC=gcc,
delete this if you don't have GNU C.  The ksh makefile also
contains some options, including JOBS (BSD/POSIX job control)
and EDIT (emacs command editing).

PD KornShell assumes you have standard C (ANSI) and POSIX header
files and functions. Since you probably don't, they are provided
in the "std" directory.

The Alpha test version will probably come as two tar files.
std.tar contains standard C and POSIX emulation and must be
extracted into a directory called std.  ksh.tar contains the ksh
source and should be extracted into a directory called src or
ksh.

See std/ReadMe and install it. Only then can you make ksh in the
"src" directory.

To clear up questions about the origin of this shell, this shell
is NOT based on the "Minix shell".  It is based on Charles
Forsyth's public domain V7 shell, which he later contributed to
Minix.

I have permission directly from Charles Forsyth to use his shell.
