Here is an overview of my PD KornShell (not related to GNU's).

- (almost) SysV/POSIX compatible.
- a subset of AT&T KornShell (it is small, will fit in 64K minus -o emacs).
- faster that csh (not surprising, if you know how csh works).
- integer variables and expressions, but no arrays or other attributes.
- BRL emacs editing mode (similar to Korn's).
- the following Korn builtins:
print getopts typeset whence alias unalias hash* let fc jobs fg bg kill bind*

I use it as my login shell but it is still under development.
I don't know when it will be ready for beta-testing.
