This is a partial history of this shell gleened from old change logs and
readmes (most of which are still in the misc directory) and the source
code. Hopefully it is correct and no contributors have been left out
readmes and source code.
Hopefully it is correct and no contributors have been left out

Release history:
* Eric Gisin (egisin@math.uwaterloo.ca), created pdksh, using
Charles Forsyth's public domain V7 shell as a base; also used parts
of the BRL shell (written by Doug A Gwyn, Doug Kingston, Ron Natalie,
Arnold Robbins, Lou Salkind, and others?, circa '87; the parts used in
pdksh included getopts, test builtin, ulimit, tty setting/getting, emacs
editing, and job control; the test builtin was based on code by Erik
Baalbergen).
