-PD-ksh is a mostly complete AT&T ksh look-alike (see NOTES file for a list
-of things not supported).  Work is mostly finished to make it fully
-compatible with both POSIX and AT&T ksh (when the two don't conflict).
-
-Since pdksh is free and compiles and runs on most common unix systems, it
-is very useful in creating a consistent user interface across multiple
-machines.  For example, in the CS dept. of MUN, pdksh is installed on a
-variety of machines including Suns, HPs, DecStations, pcs running Linux,
-etc., and is the login shell of ~5200 users.

-  * Applied some patches from OpenBSD:
-    + Use mkstemp to create temporary files	
-    + Kill -s now works
-    + Escapes special characters in tab completitions
-    + Introduce FSH flag, which is set when the shell is called as `sh'.
-    + tree.c: Fix three off-by-one errors.
-    + c_sh.c: don't set close-on-exec flag on file descriptors in FSH mode
-      (closes: #154540). Documented the change in ksh(1).
-    + history.c: Compare the return from mmap with MAP_FAILED, do not cast it
-      to int and compare with -1.
-    + main.c: set edit mode to emacs by default, may be overridden by the
-      environment or the user.  Also, we want tab completion in vi by default.
-    + misc.c: use strtol() in getn().
-    + emacs.c:
-       - bind TAB (^I) to complete-list by default
-       - complete-list first completes; if that does not work, it lists
-       - fix a memleak in do_complete()
-    + edit.c:
-       - completion now works after '=' (dd), and ':' (ssh) and ` (backtick)
-       - add '#' to the list of escaped characters during vi/emacs filename
-         completion
-
-    + exec.c: Found and fixed yet another problem with `set -e' scripts
-      (see a changelog entry for 5.2.14-3), which caused `dpkg-buildpackage -B'
-      to fail on systems where /bin/sh is ksh.
-  
-    + c_sh.c: Make `set' command return 0 always, not only in the POSIX mode.
-      According to Jeff Sheinberg <jeffsh@localnet.com>, this new behaviour
-      is more compatible with SUSv2 standard and other shells (esp. ksh93)
-      (closes: #118476). Documented the change in ksh(1) man page.
-
-    + c_test.c: The special case code for "test -x" over NFS was
-      incorrect.  The right thing to do is to try access(2) first
-      (since that occurs on the NFS server side) and only check for the
-      absence of an execute bit when access(2) succeeds.
-    + edit.c: in word location, fix forward scanning so it correctly
-      account for any escaped char and not only spaces.  for "foo
-      (bar.a)" and "foo (bar a)", cd foo\ \(bar.<tab> will correctly
-      expand to foo\ \(bar.a\).
-
-    + vi.c: Buffers are not strings so use memcpy(), not strlcpy() to copy
-      them. Also add some further bounds checks in the name of paranoia.
-    + exec.c: Unbreak parameter assignment when calling bourne style
-      functions.
-    + exec.c: For the >& and <& operators, add a check for "dup from" ==
-      "dup to" and just return success if they are the same.  Fixes the
-      "ls 2>&2" problem.
-    + eval.c, exec.c, io.c, jobs.c: If "from fd" == "to fd" don't call
-      dup2() or close "from fd".
-

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.  Line
-# up the first '|' above the ':' following the base package name, and the '|'
-# on the right side marks the last column you can put a character in.  You must
-# make exactly 11 lines for the formatting to be correct.  It's also
-# customary to leave one space after the ':'.

-pdksh: PD-ksh (a clone of the AT&T Korn shell)
-pdksh: 
-pdksh: PD-ksh has most of the ksh88 features, not much of the ksh93 features,
-pdksh: and a number of its own features.
-pdksh: Strong points are: 
-pdksh: It is free and quite portable - you should be able to compile it
-pdksh: easily on pretty much any unix box. 
-pdksh: The vi editing mode is better (IMHO) than that of ksh88 or ksh93
-pdksh: (command/file completion using tab (optional), less buggy). 
-pdksh: Its weak points are that there are still a few differences from ksh88.
