+This package is a patched version of the OpenBSD ksh, which is based on
+the original PD-ksh, but heavily modified and maintained by OpenBSD
+developers. "Patched" means ported to Linux.
+You can download the source package from a mirror listed in the
+slackbuild's info file, or you can always checkout the latest source
+from OpenBSD's repository.
+
+PD-ksh is a clone of the AT&T Korn shell.
+
+PD-ksh has most of the ksh88 features, not much of the ksh93 features,
+and a number of its own features.
+Strong points are:
+It is free and quite portable - you should be able to compile it easily
+on pretty much any unix box.
+The vi editing mode is better (IMHO) than that of ksh88 or ksh93
+(command/file completion using tab (optional), less buggy).
+Its weak points are that there are still a few differences from ksh88.

+# 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 ':'.
